+Subject: [PATCH] fq_codel: add batch ability to fq_codel_drop()
+
+In presence of inelastic flows and stress, we can call
+fq_codel_drop() for every packet entering fq_codel qdisc.
+
+fq_codel_drop() is quite expensive, as it does a linear scan
+of 4 KB of memory to find a fat flow.
+Once found, it drops the oldest packet of this flow.
+
+Instead of dropping a single packet, try to drop 50% of the backlog
+of this fat flow, with a configurable limit of 64 packets per round.
+
+TCA_FQ_CODEL_DROP_BATCH_SIZE is the new attribute to make this
+limit configurable.
+
+With this strategy the 4 KB search is amortized to a single cache line
+per drop [1], so fq_codel_drop() no longer appears at the top of kernel
+profile in presence of few inelastic flows.
+
+[1] Assuming a 64byte cache line, and 1024 buckets

+Subject: [PATCH] fq_codel: add memory limitation per queue
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On small embedded routers, one wants to control maximal amount of
+memory used by fq_codel, instead of controlling number of packets or
+bytes, since GRO/TSO make these not practical.
+
+Assuming skb->truesize is accurate, we have to keep track of
+skb->truesize sum for skbs in queue.
+
+This patch adds a new TCA_FQ_CODEL_MEMORY_LIMIT attribute.
+
+I chose a default value of 32 MBytes, which looks reasonable even
+for heavy duty usages. (Prior fq_codel users should not be hurt
+when they upgrade their kernels)
+
+Two fields are added to tc_fq_codel_qd_stats to report :
+ - Current memory usage
+ - Number of drops caused by memory limits
+
+# tc qd replace dev eth1 root est 1sec 4sec fq_codel memory_limit 4M
+..
+# tc -s -d qd sh dev eth1
+qdisc fq_codel 8008: root refcnt 257 limit 10240p flows 1024

+Subject: [PATCH] fq_codel: fix NET_XMIT_CN behavior
+
+My prior attempt to fix the backlogs of parents failed.
+
+If we return NET_XMIT_CN, our parents wont increase their backlog,
+so our qdisc_tree_reduce_backlog() should take this into account.
+
+v2: Florian Westphal pointed out that we could drop the packet,
+so we need to save qdisc_pkt_len(skb) in a temp variable before
+calling fq_codel_drop()
+

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Using KSEG0ADDR makes code highly MIPS dependent and not portable.
+Thanks to the fix a68f376 ("MIPS: io.h: Define `ioremap_cache'") we can
+use ioremap_cache which is generic and supported on MIPS as well now.
+
+KSEG0ADDR was translating 0x1c000000 into 0x9c000000. With ioremap_cache
+we use MIPS's __ioremap (and then remap_area_pages). This results in
+different address (e.g. 0xc0080000) but it still should be cached as
+expected and it was successfully tested with BCM47186B0.
+
+Other than that drivers/bcma/driver_chipcommon_sflash.c nicely setups a
+struct resource for access window, but we wren't using it. Use it now
+and drop duplicated info.

+Subject: [PATCH] mtd: add arch dependency for MTD_BCM47XXSFLASH symbol
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+We dropped strict MIPS dependency for bcm47xxsflash driver in:
+commit 5651d6aaf489 ("mtd: bcm47xxsflash: use ioremap_cache() instead of
+KSEG0ADDR()") but using ioremap_cache still limits building it to few
+selected architectures only.
+
+A recent commit 57d8f7dd2132 ("bcma: allow enabling serial flash support
+on non-MIPS SoCs") automatically dropped MIPS dependency for
+MTD_BCM47XXSFLASH which broke building e.g. on powerpc and cris.
+
+The bcma change is alright as it doesn't break building bcma code in any
+way. MTD_BCM47XXSFLASH on the other hand should be limited to archs
+which need it and can build it (by providing ioremap_cache).

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+BCM53573 is a new series of Broadcom's SoCs. It's based on ARM and uses
+this old ChipCommon-based flash access. Early tests resulted in flash
+corruptions that were tracked down to using cached MMIO for flash read
+access. Switch to ioremap_nocache conditionally to support BCM53573 and
+don't break performance on old MIPS devices.

+
+This change simplifies main parsing loop logic a bit. In future it may
+be useful for moving TRX support to separated module / parser (if we
+implement support for them at some point).
+Finally parsing TRX at the end puts us in a better position as we have
+better flash layout knowledge. It may be useful e.g. if it appears there
+is more than 1 TRX partition.

+
+Probe-mounting a volume too small for UBIFS results in kernel log
+polution which might irritate users.
+Address this by silencing errors which may happen during boot if the
+rootfs is e.g. squashfs (and thus rather small) stored on a UBI volume.

+Subject: netfilter: conntrack: cache route for forwarded connections
+
+... to avoid per-packet FIB lookup if possible.
+
+The cached dst is re-used provided the input interface
+is the same as that of the previous packet in the same direction.
+
+If not, the cached dst is invalidated.
+
+For ipv6 we also need to store sernum, else dst_check doesn't work,
+pointed out by Eric Dumazet.
+
+This should speed up forwarding when conntrack is already in use
+anyway, especially when using reverse path filtering -- active RPF
+enforces two FIB lookups for each packet.
+
+Before the routing cache removal this didn't matter since RPF was performed
+only when route cache didn't yield a result; but without route cache it
+comes at higher price.
+
+Julian Anastasov suggested to add NETDEV_UNREGISTER handler to
+avoid holding on to dsts of 'frozen' conntracks.

+Subject: [PATCH] ovl: rename is_merge to is_lowest
+
+The 'is_merge' is an historical naming from when only a single lower layer
+could exist. With the introduction of multiple lower layers the meaning of
+this flag was changed to mean only the "lowest layer" (while all lower
+layers were being merged).
+
+So now 'is_merge' is inaccurate and hence renaming to 'is_lowest'

+Subject: [PATCH] ovl: override creds with the ones from the superblock mounter
+
+In user namespace the whiteout creation fails with -EPERM because the
+current process isn't capable(CAP_SYS_ADMIN) when setting xattr.
+
+A simple reproducer:
+
+$ mkdir upper lower work merged lower/dir
+$ sudo mount -t overlay overlay -olowerdir=lower,upperdir=upper,workdir=work merged
+$ unshare -m -p -f -U -r bash
+
+Now as root in the user namespace:
+
+\# touch merged/dir/{1,2,3} # this will force a copy up of lower/dir
+\# rm -fR merged/*
+
+This ends up failing with -EPERM after the files in dir has been
+correctly deleted:
+
+unlinkat(4, "2", 0) = 0
+unlinkat(4, "1", 0) = 0
+unlinkat(4, "3", 0) = 0
+close(4) = 0
+unlinkat(AT_FDCWD, "merged/dir", AT_REMOVEDIR) = -1 EPERM (Operation not
+permitted)
+
+Interestingly, if you don't place files in merged/dir you can remove it,
+meaning if upper/dir does not exist, creating the char device file works
+properly in that same location.
+
+This patch uses ovl_sb_creator_cred() to get the cred struct from the
+superblock mounter and override the old cred with these new ones so that
+the whiteout creation is possible because overlay is wrong in assuming that
+the creds it will get with prepare_creds will be in the initial user
+namespace. The old cap_raise game is removed in favor of just overriding
+the old cred struct.
+
+This patch also drops from ovl_copy_up_one() the following two lines:
+
+override_cred->fsuid = stat->uid;
+override_cred->fsgid = stat->gid;
+
+This is because the correct uid and gid are taken directly with the stat
+struct and correctly set with ovl_set_attr().

+Subject: [PATCH] ovl: proper cleanup of workdir
+
+When mounting overlayfs it needs a clean "work" directory under the
+supplied workdir.
+
+Previously the mount code removed this directory if it already existed and
+created a new one. If the removal failed (e.g. directory was not empty)
+then it fell back to a read-only mount not using the workdir.
+
+While this has never been reported, it is possible to get a non-empty
+"work" dir from a previous mount of overlayfs in case of crash in the
+middle of an operation using the work directory.
+
+In this case the left over state should be discarded and the overlay
+filesystem will be consistent, guaranteed by the atomicity of operations on
+moving to/from the workdir to the upper layer.
+
+This patch implements cleaning out any files left in workdir. It is
+implemented using real recursion for simplicity, but the depth is limited
+to 2, because the worst case is that of a directory containing whiteouts
+under "work".

+Subject: [PATCH] ubifs: Implement RENAME_EXCHANGE
+
+Adds RENAME_EXCHANGE to UBIFS, the operation itself
+is completely disjunct from a regular rename() that's
+why we dispatch very early in ubifs_reaname().
+
+RENAME_EXCHANGE used by the renameat2() system call
+allows the caller to exchange two paths atomically.
+Both paths have to exist and have to be on the same
+filesystem.

+Subject: [PATCH] ubifs: Use dirty_writeback_interval value for wbuf timer
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Right now wbuf timer has hardcoded timeouts and there is no place for
+manual adjustments. Some projects / cases many need that though. Few
+file systems allow doing that by respecting dirty_writeback_interval
+that can be set using sysctl (dirty_writeback_centisecs).
+
+Lowering dirty_writeback_interval could be some way of dealing with user
+space apps lacking proper fsyncs. This is definitely *not* a perfect
+solution but we don't have ideal (user space) world. There were already
+advanced discussions on this matter, mostly when ext4 was introduced and
+it wasn't behaving as ext3. Anyway, the final decision was to add some
+hacks to the ext4, as trying to fix whole user space or adding new API
+was pointless.
+
+We can't (and shouldn't?) just follow ext4. We can't e.g. sync on close
+as this would cause too many commits and flash wearing. On the other
+hand we still should allow some trade-off between -o sync and default
+wbuf timeout. Respecting dirty_writeback_interval should allow some sane
+cutomizations if used warily.

+Subject: [PATCH] softirq: let ksoftirqd do its job
+
+A while back, Paolo and Hannes sent an RFC patch adding threaded-able
+napi poll loop support : (https://patchwork.ozlabs.org/patch/620657/)
+
+The problem seems to be that softirqs are very aggressive and are often
+handled by the current process, even if we are under stress and that
+ksoftirqd was scheduled, so that innocent threads would have more chance
+to make progress.
+
+This patch makes sure that if ksoftirq is running, we let it
+perform the softirq work.
+
+Jonathan Corbet summarized the issue in https://lwn.net/Articles/687617/
+
+Tested:
+
+ - NIC receiving traffic handled by CPU 0
+ - UDP receiver running on CPU 0, using a single UDP socket.
+ - Incoming flood of UDP packets targeting the UDP socket.
+
+Before the patch, the UDP receiver could almost never get cpu cycles and
+could only receive ~2,000 packets per second.
+
+After the patch, cpu cycles are split 50/50 between user application and
+ksoftirqd/0, and we can effectively read ~900,000 packets per second,
+a huge improvement in DOS situation. (Note that more packets are now
+dropped by the NIC itself, since the BH handlers get less cpu cycles to
+drain RX ring buffer)
+
+Since the load runs in well identified threads context, an admin can
+more easily tune process scheduling parameters if needed.

+Subject: [PATCH] net: bgmac: clarify CONFIG_BCMA dependency
+
+The bgmac driver depends on BCMA_HOST_SOC, which is only used
+when CONFIG_BCMA is enabled. However, it is a bool option and can
+be set when CONFIG_BCMA=m, and then bgmac can be built-in, leading
+to an obvious link error:
+
+drivers/built-in.o: In function `bgmac_init':
+:(.init.text+0x7f2c): undefined reference to `__bcma_driver_register'
+drivers/built-in.o: In function `bgmac_exit':
+:(.exit.text+0x110a): undefined reference to `bcma_driver_unregister'
+
+To avoid this case, we need to depend on both BCMA and BCMA_SOC,
+as this patch does. I'm also trying to make the dependency more
+readable by splitting it into three lines, and adding a COMPILE_TEST
+alternative so we can test-build it in all configurations that
+support BCMA.
+
+The added dependency on FIXED_PHY addresses a related issue where
+we cannot call fixed_phy_register() when CONFIG_FIXED_PHY=m and
+CONFIG_BGMAC=y.

+Subject: [PATCH 1/5] net: ethernet: bgmac: change bgmac_* prints to dev_*
+ prints
+
+The bgmac_* print wrappers call dev_* prints with the dev pointer from
+the bcma core. In anticipation of removing the bcma requirement for
+this driver, these must be changed to not reference that struct. So,
+simply change all of the bgmac_* prints to their dev_* counterparts. In
+some cases netdev_* prints are more appropriate, so change those as
+well.

+Date: Thu, 7 Jul 2016 19:08:54 -0400
+Subject: [PATCH 2/5] net: ethernet: bgmac: add dma_dev pointer
+
+The dma buffer allocation, etc references a dma_dev device pointer from
+the bcma core. In anticipation of removing the bcma requirement for
+this driver, these must be changed to not reference that struct. Add a
+dma_dev device pointer to the bgmac stuct and reference that instead.

+Subject: [PATCH 3/5] net: ethernet: bgmac: move BCMA MDIO Phy code into a
+ separate file
+
+Move the BCMA MDIO phy into a separate file, as it is very tightly
+coupled with the BCMA bus. This will help with the upcoming BCMA
+removal from the bgmac driver. Optimally, this should be moved into
+phy drivers, but it is too tightly coupled with the bgmac driver to
+effectively move it without more changes to the driver.
+
+Note: the phy_reset was intentionally removed, as the mdio phy subsystem
+automatically resets the phy if a reset function pointer is present. In
+addition to the moving of the driver, this reset function is added.

+Subject: [PATCH 4/5] net: ethernet: bgmac: convert to feature flags
+
+The bgmac driver is using the bcma provides device ID and revision, as
+well as the SoC ID and package, to determine which features are
+necessary to enable, reset, etc in the driver. In anticipation of
+removing the bcma requirement for this driver, these must be changed to
+not reference that struct. In place of that, each "feature" has been
+given a flag, and the flags are enabled for their respective device and
+SoC.

+From f6a95a24957aec5bb488c3f978c4ed508177998f Mon Sep 17 00:00:00 2001
+From: Jon Mason <jon.mason@broadcom.com>
+Date: Thu, 7 Jul 2016 19:08:57 -0400
+Subject: [PATCH 5/5] net: ethernet: bgmac: Add platform device support
+
+The bcma portion of the driver has been split off into a bcma specific
+driver. This has been mirrored for the platform driver. The last
+references to the bcma core struct have been changed into a generic
+function call. These function calls are wrappers to either the original
+bcma code or new platform functions that access the same areas via MMIO.
+This necessitated adding function pointers for both platform and bcma to
+hide which backend is being used from the generic bgmac code.

+
+In case of error, the function devm_ioremap_resource() returns ERR_PTR()

+Subject: [PATCH] net: bgmac: support Ethernet core on BCM53573 SoCs
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+BCM53573 is a new series of Broadcom's SoCs. It's based on ARM and can
+be found in two packages (versions): BCM53573 and BCM47189. It shares
+some code with the Northstar family, but also requires some new quirks.
+
+First of all there can be up to 2 Ethernet cores on this SoC. If that is
+the case, they are connected to two different switch ports allowing some
+more complex/optimized setups. It seems the second unit doesn't come
+fully configured and requires some IRQ quirk.
+
+Other than that only the first core is connected to the PHY. For the
+second one we have to register fixed PHY (similarly to the Northstar),
+otherwise generic PHY driver would get some invalid info.
+
+This has been successfully tested on Tenda AC9 (BCM47189B0).

+It doesn't really change anything as BGMAC_CHIPCTL_1_IF_TYPE_RMII is
+equal to 0. It make code a bit clener, so far when reading it one could
+think we forgot to set a proper mode. It also keeps this mode code in
+sync with other ones.

+Subject: [PATCH] net: bgmac: fix reversed checks for clock control flag
+
+This fixes regression introduced by patch adding feature flags. It was
+already reported and patch followed (it got accepted) but it appears it
+was incorrect. Instead of fixing reversed condition it broke a good one.
+
+This patch was verified to actually fix SoC hanges caused by bgmac on
+BCM47186B0.
+
+Fixes: db791eb2970b ("net: ethernet: bgmac: convert to feature flags")
+Fixes: 4af1474e6198 ("net: bgmac: Fix errant feature flag check")

+Subject: [PATCH] net: add devm version of alloc_etherdev_mqs function
+
+This patch adds devm_alloc_etherdev_mqs function and devm_alloc_etherdev
+macro. These can be used for simpler netdev allocation without having to
+care about calling free_netdev.
+
+Thanks to this change drivers, their error paths and removal paths may
+get simpler by a bit.

+ it
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+So far were were allocating struct bgmac in 3 places: platform code,
+bcma code and shared bgmac_enet_probe function. The reason for this was
+bgmac_enet_probe:
+1) Requiring early-filled struct bgmac
+2) Calling alloc_etherdev on its own in order to use netdev_priv later
+
+This solution got few drawbacks:
+1) Was duplicating allocating code
+2) Required copying early-filled struct
+3) Resulted in platform/bcma code having access only to unused struct
+
+Solve this situation by simply extracting some probe code into the new
+bgmac_alloc function.

+
+Adding struct bcma_mdio was a workaround for bcma code not having access
+to the struct bgmac used in the core code. Now we don't duplicate this
+struct we can just use it internally in bcma code.
+
+This simplifies code & allows access to all bgmac driver details from
+all places in bcma code.

+Subject: [PATCH 3/3] net: bgmac: use PHY subsystem for initializing PHY
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This adds support for using bgmac with PHYs supported by standalone PHY
+drivers. Having any PHY initialization in bgmac is hacky and shouldn't
+be extended but rather removed if anyone has hardware to test it.

+ v4.10-rc1
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This includes following upstream commits:
+5519da874ad0 net: phy: broadcom: Move bcm54xx_auxctl_{read, write} to common library
+b14995ac2527 net: phy: broadcom: Add BCM54810 PHY entry
+5b4e29005123 net: phy: broadcom: add bcm54xx_auxctl_read
+d92ead16be40 net: phy: broadcom: Add support for BCM54612E
+3cf25904fe46 net: phy: broadcom: Update Auxiliary Control Register macros
+
+Other commits were skipped as they depend on other changes like
+ETHTOOL_PHY_DOWNSHIFT & DOWNSHIFT_DEV_DISABLE and new APIs like
+get_sset_count.
+
+One exception was picking new regs from commit d06f78c4232d ("net: phy:
+broadcom: Add support code for downshift/Wirespeed").

+Subject: [PATCH] spi: introduce accelerated read support for spi flash devices
+
+In addition to providing direct access to SPI bus, some spi controller
+hardwares (like ti-qspi) provide special port (like memory mapped port)
+that are optimized to improve SPI flash read performance.
+This means the controller can automatically send the SPI signals
+required to read data from the SPI flash device.
+For this, SPI controller needs to know flash specific information like
+read command to use, dummy bytes and address width.
+
+Introduce spi_flash_read() interface to support accelerated read
+over SPI flash devices. SPI master drivers can implement this callback to
+support interfaces such as memory mapped read etc. m25p80 flash driver
+and other flash drivers can call this make use of such interfaces. The
+interface should only be used with SPI flashes and cannot be used with
+other SPI devices.

+Subject: [PATCH] USB: core: let USB device know device node
+
+Although most of USB devices are hot-plug's, there are still some devices
+are hard wired on the board, eg, for HSIC and SSIC interface USB devices.
+If these kinds of USB devices are multiple functions, and they can supply
+other interfaces like i2c, gpios for other devices, we may need to
+describe these at device tree.
+
+In this commit, it uses "reg" in dts as physical port number to match
+the phyiscal port number decided by USB core, if they are the same,
+then the device node is for the device we are creating for USB core.

++Generic USB Device Properties
++
++Usually, we only use device tree for hard wired USB device.
++The reference binding doc is from:
++http://www.firmware.org/1275/bindings/usb/usb-1_0.ps
++
++Required properties:
++- compatible: usbVID,PID. The textual representation of VID, PID shall
++ be in lower case hexadecimal with leading zeroes suppressed. The
++ other compatible strings from the above standard binding could also
++ be used, but a device adhering to this binding may leave out all except
++ for usbVID,PID.
++- reg: the port number which this device is connecting to, the range
++ is 1-31.
++
++Example:
++
++&usb1 {
++ status = "okay";
++
++ #address-cells = <1>;
++ #size-cells = <0>;
++
++ hub: genesys@1 {
++ compatible = "usb5e3,608";
++ reg = <1>;
++ };

+Subject: [PATCH] usb/core: usb_alloc_dev(): fix setting of ->portnum
+
+With commit 69bec7259853 ("USB: core: let USB device know device node"),
+the port1 argument of usb_alloc_dev() gets overwritten as follows:
+
+ ... usb_alloc_dev(..., unsigned port1)
+ {
+ ...
+ if (!parent->parent) {
+ port1 = usb_hcd_find_raw_port_number(..., port1);
+ }
+ ...
+ }
+
+Later on, this now overwritten port1 gets assigned to ->portnum:
+
+ dev->portnum = port1;
+
+However, since xhci_find_raw_port_number() isn't idempotent, the
+aforementioned commit causes a number of KASAN splats like the following:
+
+ BUG: KASAN: slab-out-of-bounds in xhci_find_raw_port_number+0x98/0x170

+ usb 4-3: device not accepting address 2, error -22

+Fix this by not overwriting the port1 argument in usb_alloc_dev(), but
+storing the raw port number as required by OF in an additional variable,
+raw_port.

+Subject: [PATCH] clk: Add {devm_}clk_hw_{register,unregister}() APIs
+
+We've largely split the clk consumer and provider APIs along
+struct clk and struct clk_hw, but clk_register() still returns a
+struct clk pointer for each struct clk_hw that's registered.
+Eventually we'd like to only allocate struct clks when there's a
+user, because struct clk is per-user now, so clk_register() needs
+to change.
+
+Let's add new APIs to register struct clk_hws, but this time
+we'll hide the struct clk from the caller by returning an int
+error code. Also add an unregistration API that takes the clk_hw
+structure that was passed to the registration API. This way
+provider drivers never have to deal with a struct clk pointer
+unless they're using the clk consumer APIs.

+Subject: [PATCH] clk: Add clk_hw OF clk providers
+
+Now that we have a clk registration API that doesn't return
+struct clks, we need to have some way to hand out struct clks via
+the clk_get() APIs that doesn't involve associating struct clk
+pointers with an OF node. Currently we ask the OF provider to
+give us a struct clk pointer for some clkspec, turn that struct
+clk into a struct clk_hw and then allocate a new struct clk to
+return to the caller.
+
+Let's add a clk_hw based OF provider hook that returns a struct
+clk_hw directly, so that we skip the intermediate step of
+converting from struct clk to struct clk_hw. Eventually when
+we've converted all OF clk providers to struct clk_hw based APIs
+we can remove the struct clk based ones.
+
+It should also be noted that we change the onecell provider to
+have a flex array instead of a pointer for the array of clk_hw
+pointers. This allows providers to allocate one structure of the
+correct length in one step instead of two.

+Subject: [PATCH] usb: core: Introduce a USB port LED trigger
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This commit adds a new trigger responsible for turning on LED when USB
+device gets connected to the selected USB port. This can can useful for
+various home routers that have USB port(s) and a proper LED telling user
+a device is connected.
+
+The trigger gets its documentation file but basically it just requires
+enabling it and selecting USB ports (e.g. echo 1 > ports/usb1-1).
+
+There was a long discussion on design of this driver. Its current state
+is a result of picking them most adjustable solution as others couldn't
+handle all cases.
+
+1) It wasn't possible for the driver to register separated trigger for
+ each USB port. Some physical USB ports are handled by more than one
+ controller and so by more than one USB port. E.g. USB 2.0 physical
+ port may be handled by OHCI's port and EHCI's port.
+ It's also not possible to assign more than 1 trigger to a single LED
+ and implementing such feature would be tricky due to syncing triggers
+ and sysfs conflicts with old triggers.
+
+2) Another idea was to register trigger per USB hub. This wouldn't allow
+ handling devices with multiple USB LEDs and controllers (hubs)
+ controlling more than 1 physical port. It's common for hubs to have
+ few ports and each may have its own LED.
+
+This final trigger is highly flexible. It allows selecting any USB ports
+for any LED. It was also modified (comparing to the initial version) to
+allow choosing ports rather than having user /guess/ proper names. It
+was successfully tested on SmartRG SR400ac which has 3 USB LEDs,
+2 physical ports and 3 controllers.
+
+It was noted USB subsystem already has usb-gadget and usb-host triggers
+but they are pretty trivial ones. They indicate activity only and can't
+have ports specified.
+
+In future it may be good idea to consider adding activity support to
+usbport as well. This should allow switching to this more generic driver
+and maybe marking old ones as obsolete.
+This can be implemented with another sysfs file for setting mode. The
+default mode wouldn't change so there won't be ABI breakage and so such
+feature can be safely implemented later.
+
+There was also an idea of supporting other devices (PCI, SDIO, etc.) but
+as this driver already contains some USB specific code (and will get
+more) these should be probably separated drivers (triggers).

++USB port LED trigger
++====================
++
++This LED trigger can be used for signalling to the user a presence of USB device
++in a given port. It simply turns on LED when device appears and turns it off
++when it disappears.
++
++It requires selecting USB ports that should be observed. All available ones are
++listed as separated entries in a "ports" subdirectory. Selecting is handled by
++echoing "1" to a chosen port.
++
++Please note that this trigger allows selecting multiple USB ports for a single
++LED. This can be useful in two cases:
++
++1) Device with single USB LED and few physical ports
++
++In such a case LED will be turned on as long as there is at least one connected
++USB device.
++
++2) Device with a physical port handled by few controllers
++
++Some devices may have one controller per PHY standard. E.g. USB 3.0 physical
++port may be handled by ohci-platform, ehci-platform and xhci-hcd. If there is
++only one LED user will most likely want to assign ports from all 3 hubs.
++
++
++This trigger can be activated from user space on led class devices as shown
++below:
++
++ echo usbport > trigger
++
++This adds sysfs attributes to the LED that are documented in:
++Documentation/ABI/testing/sysfs-class-led-trigger-usbport
++
++Example use-case:
++
++ echo usbport > trigger
++ echo 1 > ports/usb1-port1
++ echo 1 > ports/usb2-port1
++ cat ports/usb1-port1
++ echo 0 > ports/usb1-port1

+Subject: [PATCH] leds: leds-gpio: Set of_node for created LED devices
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When working with Device Tree we iterate over children of "gpio-leds"
+compatible node and create LED device for each of them. We take care of
+all common DT properties (label, default trigger, state, etc.), however
+some triggers may want to support more of them.
+
+It could be useful for timer trigger to support setting delay on/off
+values with Device Tree property. Or for transient trigger to support
+e.g. duration property.
+
+We obviously should handle such properties in triggers, not in generic
+code. To let trigger drivers read properties from DT node we need to set
+of_node to point the relevant node. This change allows using all kind of
+of helpers in e.g. "activate" callbacks.

+Subject: [PATCH] leds: gpio: use OF variant of LED registering function
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+In leds-gpio we support LEDs specified in DT so we should use
+(devm_)of_led_classdev_register. This allows passing DT node as argument
+for use by the LED subsystem.

+Subject: [PATCH] regmap: make LZO cache optional
+
+Commit 2cbbb579bcbe3 ("regmap: Add the LZO cache support") added support
+for LZO compression in regcache, but there were never any users added
+afterwards. Since LZO support itself has its own size, it currently is
+rather a deoptimization.
+
+So make it optional by introducing a symbol that can be selected by
+drivers wanting to make use of it.
+
+Saves e.g. ~46 kB on MIPS (size of LZO support + regcache LZO code).

+I tried using google to find any users (even out-of-tree ones), but at
+best I found a single driver submission that was switched to RBTREE in
+subsequent resubmissions (MFD_SMSC).
+
+One could maybe also just drop the code because of no users for 5 years,
+but that would be up to the maintainer(s) to decide.

+Subject: [PATCH] MIPS: c-r4k: Use IPI calls for CM indexed cache ops
+
+The Coherence Manager (CM) can propagate address-based ("hit") cache
+operations to other cores in the coherent system, alleviating software
+of the need to use IPI calls, however indexed cache operations are not
+propagated since doing so makes no sense for separate caches.
+
+r4k_on_each_cpu() previously had a special case for CONFIG_MIPS_MT_SMP,
+intended to avoid the IPIs when the only other CPUs in the system were
+other VPEs in the same core, and hence sharing the same caches. This was
+changed by commit cccf34e9411c ("MIPS: c-r4k: Fix cache flushing for MT
+cores") to apparently handle multi-core multi-VPE systems, but it
+focussed mainly on hit cache ops, so the IPI calls were still disabled
+entirely for CM systems.
+
+This doesn't normally cause problems, but tests can be written to hit
+these corner cases by using multiple threads, or changing task
+affinities to force the process to migrate cores. For example the
+failure of mprotect RW->RX to globally sync icaches (via
+flush_cache_range) can be detected by modifying and mprotecting a code
+page on one core, and migrating to a different core to execute from it.
+
+Most of the functions called by r4k_on_each_cpu() perform cache
+operations exclusively with a single addressing-type (virtual address vs
+indexed), so add a type argument and modify the callers to pass in
+R4K_USER (user virtual addressing), R4K_KERN (global kernel virtual
+addressing) or R4K_INDEX (index into cache).
+
+local_r4k_flush_icache_range() is split up, to allow it to be called
+from the rest of the kernel, or from r4k_flush_icache_range() where it
+will choose either indexed or hit cache operations based on the size of
+the range and the cache sizes.
+
+local_r4k_flush_kernel_vmap_range() is split into two functions, each of
+which uses cache operations with a single addressing-type, with
+r4k_flush_kernel_vmap_range() making the decision whether to use indexed
+cache ops or not.

+Subject: [PATCH] MIPS: c-r4k: Exclude sibling CPUs in SMP calls
+
+When performing SMP calls to foreign cores, exclude sibling CPUs from
+the provided map, as we already handle the local core on the current
+CPU. This prevents an IPI call from for example core 0, VPE 1 to VPE 0
+on the same core.

+
+Instead of rewriting the arguments to match the UHI spec, store the
+address of a appended or UHI supplied dtb in fw_supplied_dtb.
+
+That way the original bootloader arugments are kept intact while still
+making the use of an appended dtb invisible for mach code.
+
+Mach code can still find out if it is an appended dtb by comparing
+fw_arg1 with fw_supplied_dtb.

+ icache flushes
+
+Commit f70ddc07b637 ("MIPS: c-r4k: Avoid small flush_icache_range SMP
+calls") adds checks to force use of hit-type cache ops for small icache
+flushes where they are globalised & index-type cache ops aren't, in
+order to avoid the overhead of IPIs in those cases. However it
+calculated the size of the region being flushed incorrectly, subtracting
+the end address from the start address rather than the reverse. This
+would have led to an overflow with size wrapping round to some large
+value, and likely to the special case for avoiding IPIs not actually
+being hit.

+
+Most cache flush ops were no-op for highmem pages. This led to nasty
+segfaults and (in the case of page_address(page) == NULL) kernel
+crashes.
+
+Fix this by always flushing highmem pages using kmap/kunmap_atomic
+around the actual cache flush. This might be a bit inefficient, but at
+least it's stable.

+
+This fix for ARM does not account ARCH_PFN_OFFSET for mem_map as later used by
+page_to_pfn anymore.
+
+The following output was generated with two hacked in printk statements:
+
+printk("before %p vs. %p or %p\n", mem_map, mem_map - offset, mem_map -
+(pgdat->node_start_pfn - ARCH_PFN_OFFSET));
+ if (page_to_pfn(mem_map) != pgdat->node_start_pfn)
+ mem_map -= offset + (pgdat->node_start_pfn - ARCH_PFN_OFFSET);
+printk("after %p\n", mem_map);
+
+Output:
+
+[ 0.000000] before 8861b280 vs. 8861b280 or 8851b280
+[ 0.000000] after 8851b280
+
+As seen in the first line mem_map with subtraction of offset does not equal the
+mem_map after subtraction of ARCH_PFN_OFFSET.
+
+After adding the offset of ARCH_PFN_OFFSET as well to mem_map as the
+previously calculated offset is zero for the named platform it is able to boot
+4.4 and 4.9-rc7 again.

+Subject: bridge: allow receiption on disabled port
+
+When an ethernet device is enslaved to a bridge, and the bridge STP
+detects loss of carrier (or operational state down), then normally
+packet receiption is blocked.
+
+This breaks control applications like WPA which maybe expecting to
+receive packets to negotiate to bring link up. The bridge needs to
+block forwarding packets from these disabled ports, but there is no
+hard requirement to not allow local packet delivery.

+Subject: [PATCH] MIPS: partially inline dma ops
+
+Several DMA ops are no-op on many platforms, and the indirection through
+the mips_dma_map_ops function table is causing the compiler to emit
+unnecessary code.
+
+Inlining visibly improves network performance in my tests (on a 24Kc
+based system), and also slightly reduces code size of a few drivers.

+Subject: [PATCH 2/3] mtd: part: add generic parsing of linux,part-probe
+
+This moves the linux,part-probe device tree parsing code from
+physmap_of.c to mtdpart.c. Now all drivers can use this feature by just
+providing a reference to their device tree node in struct
+mtd_part_parser_data.

+Subject: [PATCH] Revert "bcma: init serial console directly from ChipCommon
+ code"
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This reverts commit 4c81acab3816 ("bcma: init serial console directly
+from ChipCommon code") as it broke IRQ assignment. Getting IRQ with
+bcma_core_irq helper on SoC requires MIPS core to be set. It happens
+*after* ChipCommon initialization so we can't do this so early.
+
+This fixes a user reported regression. It wasn't critical as serial was
+still somehow working but lack of IRQs was making in unreliable.
+
+Fixes: 4c81acab3816 ("bcma: init serial console directly from ChipCommon code")
+Reported-by: Felix Fietkau <nbd@nbd.name>
+Cc: stable@vger.kernel.org # 4.6+

+Subject: [PATCH 1/3] uapi/kernel.h: glibc specific inclusion of sysinfo.h
+
+including sysinfo.h from kernel.h makes no sense whatsoever,
+but removing it breaks glibc's userspace header,
+which includes kernel.h instead of sysinfo.h from their sys/sysinfo.h.
+this seems to be a historical mistake.
+on musl, including any header that uses kernel.h directly or indirectly
+plus sys/sysinfo.h will produce a compile error due to redefinition of
+struct sysinfo from sys/sysinfo.h.
+so for now, only include it on glibc or when including from kernel
+in order not to break their headers.

+Subject: [PATCH 2/3] uapi/libc-compat.h: do not rely on __GLIBC__
+
+Musl provides the same structs as glibc, but does not provide a define to
+allow its detection. Since the absence of __GLIBC__ also can mean that it
+is included from the kernel, change the __GLIBC__ detection to
+!__KERNEL__, which should always be true when included from userspace.

+
+This small patch makes the MIPS FPU emulator optional. The kernel

+Disabling the emulator shrinks vmlinux by about 54kBytes (32bit,
+optimizing for size).

+v4: rediffed because of patch 1/2, should now work with micromips as well
+v3: updated patch description with size savings.
+v2: incorporated changes suggested by Jonas Gorski
+ force the fpu emulator on for micromips: relocating the parts
+ of the mmips code in the emulator to other areas would be a
+ much larger change; I went the cheap route instead with this.

++ help
++ This option lets you disable the built-in MIPS FPU (Coprocessor 1)
++ emulator, which handles floating-point instructions on processors
++ without a hardware FPU. It is generally a good idea to keep the
++ emulator built-in, unless you are perfectly sure you have a
++ complete soft-float environment. With the emulator disabled, all
++ users of float operations will be killed with an illegal instr-
++ uction exception.
++
++ Say Y, please.

+Subject: [PATCH 1/2] openwrt: arc - remove dependency on DEVTMPFS
+
+OpenWRT builds initramfs so that it doesn't require DEVTMPFS so dropping
+this dependency. That helps to escape 2 separate kernel rebuilds with
+and without initramfs.
+
+2 builds happen because OpenWRT first builds kernel and later modules.
+When building entire kernel with simple "make" INITRAMFS sets to a real
+value and so was triggering DEVTMPFS selection. Then when building only
+modules with "make modules" command INITRAMFS is zeroed and so kernel
+config was changing that lead to full kernel rebuild.

+This change allows OpenWRT to patch resulting kernel binary with

+given its ARC core configurations match (at least cache line sizes etc).
+
+""patch-dtb" searches for ASCII "OWRTDTB:" strign and copies external
+.dtb right after it, keeping the string in place.

++ MyLoader is a bootloader which allows the user to define partitions

++ on the device, similar to a partition table. This table gives the

++ If you need code which can detect and parse these tables, and

++
++ You will still need the parsing functions to be called by the driver
++ for your particular device. It won't happen automatically.

+Date: Thu, 22 May 2014 09:49:05 +0200
+Subject: [PATCH] Add support for MAP-E FMRs (mesh mode)
+
+MAP-E FMRs (draft-ietf-softwire-map-10) are rules for IPv4-communication
+between MAP CEs (mesh mode) without the need to forward such data to a
+border relay. This is similar to how 6rd works but for IPv4 over IPv6.

+
+RFC6204 L-14 requires rejecting traffic from invalid addresses with
+ICMPv6 Destination Unreachable, Code 5 (Source address failed ingress/

+Subject: NET: skip GRO for foreign MAC addresses
+
+For network drivers using napi_gro_receive, packets are run through GRO,
+even when the destination MAC address does not match, and they're supposed
+to be delivered to another host behind a different bridge port.
+
+This can be very expensive, because for drivers without TSO or scatter-
+gather, this can only be undone by copying the skb and checksumming it
+again.
+
+To be able to track foreign MAC addresses in an inexpensive way, create
+a mask of changed bits in MAC addresses of upper devices. This allows
+handling VLANs and bridge devices with different addresses (as long as
+they are not too different).

+Subject: NET: add mtd-mac-address support to of_get_mac_address()
+
+Many embedded devices have information such as mac addresses stored inside mtd
+devices. This patch allows us to add a property inside a node describing a
+network interface. The new property points at a mtd partition with an offset
+where the mac address can be found.

+Subject: [PATCH] at803x: fix reset handling
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The driver of course "knows" that the chip's reset signal is active low,
+so it drives the GPIO to 0 to reset the PHY and to 1 otherwise; however
+all this will only work iff the GPIO is specified as active-high in the
+device tree! I think both the driver and the device trees (if there are
+any -- I was unable to find them) need to be fixed in this case...

+Subject: [PATCH] net: phy: at803x: Request 'reset' GPIO only for AT8030 PHY
+
+This removes the dependency on GPIOLIB for non faulty PHYs.
+
+Indeed, without this patch, if GPIOLIB is not selected
+devm_gpiod_get_optional() will return -ENOSYS and the driver probe
+call will fail, regardless of the actual PHY hardware.
+
+Out of the 3 PHYs supported by this driver (AT8030, AT8031, AT8035),
+only AT8030 presents the issues that commit 13a56b449325 ("net: phy:
+at803x: Add support for hardware reset") attempts to work-around by
+using a 'reset' GPIO line.
+
+Hence, only AT8030 should depend on GPIOLIB operating properly.

+Subject: [PATCH] net: phy: at803x: only the AT8030 needs a hardware reset on
+ link change
+
+Commit 13a56b44 ("at803x: Add support for hardware reset") added a
+work-around for a hardware bug on the AT8030. However, the work-around
+was being called for all 803x PHYs, even those that don't need it.
+Function at803x_link_change_notify() checks to make sure that it only
+resets the PHY on the 8030, but it makes more sense to not call that
+function at all if it isn't needed.

+
+There're some discussions in mailing lists proposing to disable
+that particular check alltogether and magically all seem to work
+fine with muted warning.
+
+Anyways new thread on that regard could be found here:
+http://lists.infradead.org/pipermail/linux-snps-arc/2016-July/001310.html
+
+Let's see what comes out of that new discussion, hopefully patching
+of generic USB stuff won't be required then.

+Subject: [PATCH] libata: add ledtrig support
+To: linux-ide@vger.kernel.org,
+ Tejun Heo <tj@kernel.org>
+
+This adds a LED trigger for each ATA port indicating disk activity.
+
+As this is needed only on specific platforms (NAS SoCs and such),
+these platforms should define ARCH_WANTS_LIBATA_LEDS if there
+are boards with LED(s) intended to indicate ATA disk activity and
+need the OS to take care of that.
+In that way, if not selected, LED trigger support not will be
+included in libata-core and both, codepaths and structures remain
+untouched.
