+Subject: [PATCH] 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] mtd: keep original flags for every struct mtd_info
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When allocating a new partition mtd subsystem runs internal tests in the
+allocate_partition(). They may result in modifying specified flags (e.g.
+dropping some /features/ like write access).
+
+Those constraints don't have to be necessary true for subpartitions. It
+may happen parent partition isn't block aligned (effectively disabling
+write access) while subpartition may fit blocks nicely. In such case all
+checks should be run again (starting with original flags value).

+2) Makes bcma_bus_get_host_dev() unneeded
+3) Allows further improvements like using dev_* printing helpers

+Subject: [PATCH 1/1] Allow class-e address assignment in ifconfig and early
+ boot
+
+While the linux kernel became mostly "class-e clean" a decade ago,
+and most distributions long ago switched to the iproute2 suite
+of utilities, which allow class-e (240.0.0.0/4) address assignment,
+distributions relying on busybox, toybox and other forms of
+ifconfig cannot assign class-e addresses without this kernel patch.
+
+With this patch, also, a boot command line on these addresses is feasible:
+(ip=248.0.1.2::248.0.1.1:255.255.255.0).
+
+While CIDR has been obsolete for 2 decades, and a survey of all the
+userspace open source code in the world shows most IN_whatever macros
+are also obsolete... rather than obsolete CIDR from this ioctl entirely,
+this patch merely enables class-e assignment, sanely.
+
+H/T to Vince Fuller and his original patch here:

+Subject: [PATCH 2/2] arm: cns3xxx: use actual size reads for PCIe
+
+commit 802b7c06adc7 ("ARM: cns3xxx: Convert PCI to use generic config accessors")
+reimplemented cns3xxx_pci_read_config() using pci_generic_config_read32(),
+which preserved the property of only doing 32-bit reads.
+
+It also replaced cns3xxx_pci_write_config() with pci_generic_config_write(),
+so it changed writes from always being 32 bits to being the actual size,
+which works just fine.
+
+Due to:
+- The documentation does not mention that only 32 bit access is allowed.
+- Writes are already executed using the actual size
+- Extensive testing shows that 8b, 16b and 32b reads work as intended
+
+It makes perfectly sense to also swap 32 bit reading in favor of actual size.
+
+Fixes: 802b7c06adc7 ("ARM: cns3xxx: Convert PCI to use generic config accessors")

+Subject: usb: dwc2: Set lpm mode parameters depend on HW configuration
+
+If core not supported lpm, i.e. BCM2835 then confusing warnings seen
+in log.
+
+To avoid these warnings, added function dwc2_set_param_lpm() to set
+lpm and other lpm related parameters based on lpm support by core.

+Subject: [PATCH] arm64/sve: Disentangle <uapi/asm/ptrace.h> from
+ <uapi/asm/sigcontext.h>
+
+Currently, <uapi/asm/sigcontext.h> provides common definitions for
+describing SVE context structures that are also used by the ptrace
+definitions in <uapi/asm/ptrace.h>.
+
+For this reason, a #include of <asm/sigcontext.h> was added in
+ptrace.h, but it this turns out that this can interact badly with
+userspace code that tries to include ptrace.h on top of the libc
+headers (which may provide their own shadow definitions for
+sigcontext.h).
+
+To make the headers easier for userspace to consume, this patch
+bounces the common definitions into an __SVE_* namespace and moves
+them to a backend header <uapi/asm/sve_context.h> that can be
+included by the other headers as appropriate.  This should allow
+ptrace.h to be used alongside libc's sigcontext.h (if any) without
+ill effects.
+
+This should make the situation unambiguous: <asm/sigcontext.h> is
+the header to include for the sigframe-specific definitions, while
+<asm/ptrace.h> is the header to include for ptrace-specific
+definitions.
+
+To avoid conflicting with existing usage, <asm/sigcontext.h>
+remains the canonical way to get the common definitions for
+SVE_VQ_MIN, sve_vq_from_vl() etc., both in userspace and in the
+kernel: relying on these being defined as a side effect of
+including just <asm/ptrace.h> was never intended to be safe.

+Subject: [PATCH] netfilter: nf_flow_table: fix offloaded connection timeout
+ corner case
+
+The full teardown of offloaded flows is deferred to a gc work item,
+however processing of packets by netfilter needs to happen immediately
+after a teardown is requested, because the conntrack state needs to be
+fixed up.
+
+Since the IPS_OFFLOAD_BIT is still kept until the teardown is complete,
+the netfilter conntrack gc can accidentally bump the timeout of a
+connection where offload was just stopped, causing a conntrack entry
+leak.
+
+Fix this by moving the conntrack timeout bumping from conntrack core to
+the nf_flow_offload and add a check to prevent bogus timeout bumps.

+Subject: [PATCH] net: sched: Backport Introduce act_ctinfo action
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+ctinfo is a new tc filter action module.  It is designed to restore
+information contained in firewall conntrack marks to other packet fields
+and is typically used on packet ingress paths.  At present it has two
+independent sub-functions or operating modes, DSCP restoration mode &
+skb mark restoration mode.
+
+The DSCP restore mode:
+
+This mode copies DSCP values that have been placed in the firewall
+conntrack mark back into the IPv4/v6 diffserv fields of relevant
+packets.
+
+The DSCP restoration is intended for use and has been found useful for
+restoring ingress classifications based on egress classifications across
+links that bleach or otherwise change DSCP, typically home ISP Internet
+links.  Restoring DSCP on ingress on the WAN link allows qdiscs such as
+but by no means limited to CAKE to shape inbound packets according to
+policies that are easier to set & mark on egress.
+
+Ingress classification is traditionally a challenging task since
+iptables rules haven't yet run and tc filter/eBPF programs are pre-NAT
+lookups, hence are unable to see internal IPv4 addresses as used on the
+typical home masquerading gateway.  Thus marking the connection in some
+manner on egress for later restoration of classification on ingress is
+easier to implement.
+
+Parameters related to DSCP restore mode:
+
+dscpmask - a 32 bit mask of 6 contiguous bits and indicate bits of the
+conntrack mark field contain the DSCP value to be restored.
+
+statemask - a 32 bit mask of (usually) 1 bit length, outside the area
+specified by dscpmask.  This represents a conditional operation flag
+whereby the DSCP is only restored if the flag is set.  This is useful to
+implement a 'one shot' iptables based classification where the
+'complicated' iptables rules are only run once to classify the
+connection on initial (egress) packet and subsequent packets are all
+marked/restored with the same DSCP.  A mask of zero disables the
+conditional behaviour ie. the conntrack mark DSCP bits are always
+restored to the ip diffserv field (assuming the conntrack entry is found
+& the skb is an ipv4/ipv6 type)
+
+e.g. dscpmask 0xfc000000 statemask 0x01000000
+
+|----0xFC----conntrack mark----000000---|
+| Bits 31-26 | bit 25 | bit24 |~~~ Bit 0|
+| DSCP       | unused | flag  |unused   |
+|-----------------------0x01---000000---|
+      |                   |
+      |                   |
+      ---|             Conditional flag
+         v             only restore if set
+|-ip diffserv-|
+| 6 bits      |
+|-------------|
+
+The skb mark restore mode (cpmark):
+
+This mode copies the firewall conntrack mark to the skb's mark field.
+It is completely the functional equivalent of the existing act_connmark
+action with the additional feature of being able to apply a mask to the
+restored value.
+
+Parameters related to skb mark restore mode:
+
+mask - a 32 bit mask applied to the firewall conntrack mark to mask out
+bits unwanted for restoration.  This can be useful where the conntrack
+mark is being used for different purposes by different applications.  If
+not specified and by default the whole mark field is copied (i.e.
+default mask of 0xffffffff)
+
+e.g. mask 0x00ffffff to mask out the top 8 bits being used by the
+aforementioned DSCP restore mode.
+
+|----0x00----conntrack mark----ffffff---|
+| Bits 31-24 |                          |
+| DSCP & flag|      some value here     |
+|---------------------------------------|
+			|
+			|
+			v
+|------------skb mark-------------------|
+|            |                          |
+|  zeroed    |                          |
+|---------------------------------------|
+
+Overall parameters:
+
+zone - conntrack zone
+
+control - action related control (reclassify | pipe | drop | continue |
+ok | goto chain <CHAIN_INDEX>)

+Subject: [PATCH 1/8] mtd: spinand: winbond: Add support for W25N01GV
+
+W25N01GV is a single die version of the already supported
+W25M02GV with half the capacity. Everything else is the
+same so introduce support for W25N01GV.
+
+Datasheet:http://www.winbond.com/resource-files/w25n01gv%20revl%20050918%20unsecured.pdf
+
+Tested on 8devices Jalapeno dev board under OpenWrt running 4.19-rc5.

+IMPORTANT NOTE
+==============
+
+The content of this patch has been adapted for Linux 4.19
+
+Changes were made in Linux 5.x to add the bad-block limit
+to the metadata available to the driver, adding a parameter
+
+NAND_MEMORG(1, 2048, 128, 64, 1024, 20, 1, 1, 1),
+                                     ^- New bad-block limit
+
+This patch omits that parameter from the upstream patch
+for compatibility with the Linux 4.19 driver.

+Subject: [PATCH 3/3] mtd: spinand: Add support for GigaDevice GD5F1GQ4UFxxG
+
+The GigaDevice GD5F1GQ4UFxxG SPI NAND is in current production devices
+and, while it has the same logical layout as the E-series devices,
+it differs in the SPI interfacing in significant ways.
+
+This support is contingent on previous commits to:
+
+  * Add support for two-byte device IDs
+  * Define macros for page-read ops with three-byte addresses

+Subject: [PATCH 602/660] net: phy: Stop with excessive soft reset
+
+While consolidating the PHY reset in phy_init_hw() an unconditionaly
+BMCR soft-reset I became quite trigger happy with those. This was later
+on deactivated for the Generic PHY driver on the premise that a prior
+software entity (e.g: bootloader) might have applied workarounds in
+commit 0878fff1f42c ("net: phy: Do not perform software reset for
+Generic PHY").
+
+Since we have a hook to wire-up a soft_reset callback, just use that and
+get rid of the call to genphy_soft_reset() entirely. This speeds up
+initialization and link establishment for most PHYs out there that do
+not require a reset.
+
+Fixes: 87aa9f9c61ad ("net: phy: consolidate PHY reset in phy_init_hw()")

+Subject: [PATCH 604/660] net: phy: add register modifying helpers returning 1
+ on change
+
+When modifying registers there are scenarios where we need to know
+whether the register content actually changed. This patch adds
+new helpers to not break users of the current ones, phy_modify() etc.

+Subject: [PATCH 607/660] net: phylink: support for link gpio interrupt
+
+Add support for using GPIO interrupts with a fixed-link GPIO rather than
+polling the GPIO every second and invoking the phylink resolution.  This
+avoids unnecessary calls to mac_config().

+
+Avoid reducing the support mask as a result of the interface type
+selected for SFP modules, or when setting the link settings through
+ethtool - this should only change when the supported link modes of
+the hardware combination change.

+Subject: [PATCH 612/660] net: sfp: Stop SFP polling and interrupt handling
+ during shutdown
+
+SFP device polling can cause problems during the shutdown process if the
+parent devices of the network controller have been shut down already.
+This problem was seen on the iMX6 platform with PCIe devices, where
+accessing the device after the bus is shut down causes a hang.
+
+Free any acquired GPIO interrupts and stop all delayed work in the SFP
+driver during the shutdown process, so that we ensure that no pending
+operations are still occurring after the SFP shutdown completes.

+Subject: [PATCH 613/660] net: phylink: don't start and stop SGMII PHYs in SFP
+ modules twice
+
+SFP modules connected using the SGMII interface have their own PHYs which
+are handled by the struct phylink's phydev field. On the other hand, for
+the modules connected using 1000Base-X interface that field is not set.
+
+Since commit ce0aa27ff3f6 ("sfp: add sfp-bus to bridge between network
+devices and sfp cages") phylink_start() ends up setting the phydev field
+using the sfp-bus infrastructure, which eventually calls phy_start() on it,
+and then calling phy_start() again on the same phydev from phylink_start()
+itself. Similar call sequence holds for phylink_stop(), only in the reverse
+order. This results in WARNs during network interface bringup and shutdown
+when a copper SFP module is connected, as phy_start() and phy_stop() are
+called twice in a row for the same phy_device:

+Subject: [PATCH 615/660] net: sfp: rework upstream interface
+
+The current upstream interface is an all-or-nothing, which is
+sub-optimal for future changes, as it doesn't allow the upstream driver
+to prepare for the SFP module becoming available, as it is at boot.
+
+Switch to a find-sfp-bus, add-upstream, del-upstream, put-sfp-bus
+interface structure instead, which allows the upstream driver to
+prepare for a module being available as soon as add-upstream is called.

+Subject: [PATCH 625/660] net: sfp: control TX_DISABLE and phy only from main
+ state machine
+
+We initialise TX_DISABLE when the sfp cage is probed, and then
+maintain its state in the main state machine.  However, the module
+state machine:
+- negates it when detecting a newly inserted module when it's already
+  guaranteed to be negated.
+- negates it when the module is removed, but the main state machine
+  will do this anyway.
+
+Make TX_DISABLE entirely controlled by the main state machine.
+
+The main state machine also probes the module for a PHY, and removes
+the PHY when the the module is removed.  Hence, removing the PHY in
+sfp_sm_module_remove() is also redundant, and is a left-over from
+when we tried to probe for the PHY from the module state machine.

+
+Move the PHY probe into a separate function, splitting it from
+sfp_sm_mod_init().  This will allow us to eliminate the 50ms mdelay()
+inside the state machine.

+Rather than using mdelay() to wait before probing the PHY (which holds

+Subject: [PATCH 629/660] net: sfp: ensure TX_FAULT has deasserted before
+ probing the PHY
+
+TX_FAULT should be deasserted to indicate that the module has completed
+its initialisation.  This may include the on-board PHY, so wait until
+the module has deasserted TX_FAULT before probing the PHY.
+
+This means that we need an extra state to handle a TX_FAULT that
+remains set for longer than t_init, since using the existing handling
+state would bypass the PHY probe.

+Subject: [PATCH 630/660] net: sfp: track upstream's attachment state in state
+ machine
+
+Track the upstream's attachment state in the state machine rather than
+maintaining a boolean, which ensures that we have a strict order of
+ATTACH followed by an UP event - we can never believe that a newly
+attached upstream will be anything but down.
+
+Rearrange the order of state machines so we run the module state
+machine after the upstream device's state machine, so the module state
+machine can check the current state of the device and take action to
+e.g. reset back to empty state when the upstream is detached.
+
+This is to allow the module detection to run independently of the
+network device becoming available.

+Subject: [PATCH 631/660] net: sfp: split power mode switching from probe
+
+Switch the power mode switching from the probe, so that we don't
+repeatedly re-probe the SFP device if there is a problem accessing
+the registers at I2C address 0x51.
+
+In splitting this out, we can also fix a bug where we leave the module
+in high-power mode when the upstream device is detached but the module
+is still inserted.

+Subject: [PATCH 632/660] net: sfp: move module insert reporting out of probe
+
+Move the module insertion reporting out of the probe handling, but
+after we have detected that the upstream has attached (since that is
+whom we are reporting insertion to.)
+
+Only report module removal if we had previously reported a module
+insertion.
+
+This gives cleaner semantics, and means we can probe the module before
+we have an upstream attached.

+Subject: [PATCH 633/660] net: sfp: allow sfp to probe slow to initialise GPON
+ modules
+
+Some GPON modules (e.g. Huawei MA5671A) take a significant amount of
+time to start responding on the I2C bus, contary to the SFF
+specifications.
+
+Work around this by implementing a two-level timeout strategy, where
+we initially quickly retry for the module, and then use a slower retry
+after we exceed a maximum number of quick attempts.

+Subject: [PATCH 634/660] net: sfp: allow modules with slow diagnostics to
+ probe
+
+When a module is inserted, we attempt to read read the ID from address
+0x50.  Once we are able to read the ID, we immediately attempt to
+initialise the hwmon support by reading from address 0x51.  If this
+fails, then we fall into error state, and assume that the module is
+not usable.
+
+Modules such as the ALCATELLUCENT 3FE46541AA use a real EEPROM for
+I2C address 0x50, which responds immediately.  However, address 0x51
+is an emulated, which only becomes available once the on-board firmware
+has booted.  This prompts us to fall into the error state.
+
+Since the module may be usable without diagnostics, arrange for the
+hwmon probe independent of the rest of the SFP itself, retrying every
+5s for up to about 60s for the monitoring to become available, and
+print an error message if it doesn't become available.

+
+Add support for SFP+ cages to the Marvell 10G PHY driver. This is
+slightly complicated by the way phylib works in that we need to use
+a multi-step process to attach the SFP bus, and we also need to track
+the phylink state machine to know when the module's transmit disable
+signal should change state.
+
+With appropriate DT changes, this allows the SFP+ canges on the

+Subject: [PATCH 638/660] net: phy: avoid matching all-ones clause 45 PHY IDs
+
+We currently match clause 45 PHYs using any ID read from a MMD marked
+as present in the "Devices in package" registers 5 and 6.  However,
+this is incorrect.  45.2 says:
+
+  "The definition of the term package is vendor specific and could be
+   a chip, module, or other similar entity."
+
+so a package could be more or less than the whole PHY - a PHY could be
+made up of several modules instantiated onto a single chip such as the
+Marvell 88x3310, or some of the MMDs could be disabled according to
+chip configuration, such as the Broadcom 84881.
+
+In the case of Broadcom 84881, the "Devices in package" registers
+contain 0xc000009b, meaning that there is a PHYXS present in the
+package, but all registers in MMD 4 return 0xffff.  This leads to our
+matching code incorrectly binding this PHY to one of our generic PHY
+drivers.
+
+This patch changes the way we determine whether to attempt to match a
+MMD identifier, or use it to request a module - if the identifier is
+all-ones, then we skip over it. When reading the identifiers, we
+initialise phydev->c45_ids.device_ids to all-ones, only reading the
+device ID if the "Devices in package" registers indicates we should.
+
+This avoids the generic drivers incorrectly matching on a PHY ID of

+Subject: [PATCH 639/660] net: phylink: fix link mode modification in PHY mode
+
+Modifying the link settings via phylink_ethtool_ksettings_set() and
+phylink_ethtool_set_pauseparam() didn't always work as intended for
+PHY based setups, as calling phylink_mac_config() would result in the
+unresolved configuration being committed to the MAC, rather than the
+configuration with the speed and duplex setting.
+
+This would work fine if the update caused the link to renegotiate,
+but if no settings have changed, phylib won't trigger a renegotiation
+cycle, and the MAC will be left incorrectly configured.
+
+Avoid calling phylink_mac_config() unless we are using an inband mode
+in phylink_ethtool_ksettings_set(), and use phy_set_asym_pause() as
+introduced in 4.20 to set the PHY settings in
+phylink_ethtool_set_pauseparam().

+Subject: hack: arch: powerpc: drop register save/restore library from modules
+
+Upstream GCC uses a libgcc function for saving/restoring registers. This
+makes the code bigger, and upstream kernels need to carry that function
+for every single kernel module. Our GCC is patched to avoid those

+Date: Thu, 14 Nov 2019 15:50:07 -0800
+Subject: loop: Report EOPNOTSUPP properly
+
+Properly plumb out EOPNOTSUPP from loop driver operations, which may
+get returned when for instance a discard operation is attempted but not
+supported by the underlying block device. Before this change, everything
+was reported in the log as an I/O error, which is scary and not
+helpful in debugging.

+Subject: loop: Better discard support for block devices
+
+If the backing device for a loop device is itself a block device,
+then mirror the "write zeroes" capabilities of the underlying
+block device into the loop device. Copy this capability into both
+max_write_zeroes_sectors and max_discard_sectors of the loop device.
+
+The reason for this is that REQ_OP_DISCARD on a loop device translates
+into blkdev_issue_zeroout(), rather than blkdev_issue_discard(). This
+presents a consistent interface for loop devices (that discarded data
+is zeroed), regardless of the backing device type of the loop device.
+There should be no behavior change for loop devices backed by regular
+files.
+
+This change fixes blktest block/003, and removes an extraneous
+error print in block/013 when testing on a loop device backed
+by a block device that does not support discard.

+Subject: [PATCH] netfilter: connmark: introduce set-dscpmark
+
+set-dscpmark is a method of storing the DSCP of an ip packet into
+conntrack mark.  In combination with a suitable tc filter action
+(act_ctinfo) DSCP values are able to be stored in the mark on egress and
+restored on ingress across links that otherwise alter or bleach DSCP.
+
+This is useful for qdiscs such as CAKE which are able to shape according
+to policies based on DSCP.
+
+Ingress classification is traditionally a challenging task since
+iptables rules haven't yet run and tc filter/eBPF programs are pre-NAT
+lookups, hence are unable to see internal IPv4 addresses as used on the
+typical home masquerading gateway.
+
+x_tables CONNMARK set-dscpmark target solves the problem of storing the
+DSCP to the conntrack mark in a way suitable for the new act_ctinfo tc
+action to restore.
+
+The set-dscpmark option accepts 2 parameters, a 32bit 'dscpmask' and a
+32bit 'statemask'.  The dscp mask must be 6 contiguous bits and
+represents the area where the DSCP will be stored in the connmark.  The
+state mask is a minimum 1 bit length mask that must not overlap with the
+dscpmask.  It represents a flag which is set when the DSCP has been
+stored in the conntrack mark. This is useful to implement a 'one shot'
+iptables based classification where the 'complicated' iptables rules are
+only run once to classify the connection on initial (egress) packet and
+subsequent packets are all marked/restored with the same DSCP.  A state
+mask of zero disables the setting of a status bit/s.
+
+example syntax with a suitably modified iptables user space application:
+
+iptables -A QOS_MARK_eth0 -t mangle -j CONNMARK --set-dscpmark 0xfc000000/0x01000000
+
+Would store the DSCP in the top 6 bits of the 32bit mark field, and use
+the LSB of the top byte as the 'DSCP has been stored' marker.

+Subject: [PATCH v2] MIPS: perf: ath79: Fix perfcount IRQ assignment
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Currently it's not possible to use perf on ath79 due to genirq flags
+mismatch happening on static virtual IRQ 13 which is used for
+performance counters hardware IRQ 5.
+
+On TP-Link Archer C7v5:
+
+           CPU0
+  2:          0      MIPS   2  ath9k

+  7:      55034      MIPS   7  timer
+  8:       1236      MISC   3  ttyS0

+ 13:          0  gpio-ath79   2  keys

+ 15:         31  AR724X PCI    1  ath10k_pci
+
+ $ perf top
+ genirq: Flags mismatch irq 13. 00014c83 (mips_perf_pmu) vs. 00002003 (keys)
+
+On TP-Link Archer C7v4:
+
+         CPU0
+  4:          0      MIPS   4  19000000.eth
+  5:       7135      MIPS   5  1a000000.eth
+  7:      98379      MIPS   7  timer
+  8:         30      MISC   3  ttyS0
+ 12:      90028      INTC   0  ath9k
+ 13:       5520      INTC   1  ehci_hcd:usb1
+ 14:       4623      INTC   2  ehci_hcd:usb2
+ 15:      32844  AR724X PCI    1  ath10k_pci
+ 16:          0  gpio-ath79  16  keys
+ 23:          0  gpio-ath79  23  keys
+
+ $ perf top
+ genirq: Flags mismatch irq 13. 00014c80 (mips_perf_pmu) vs. 00000080 (ehci_hcd:usb1)
+
+This problem is happening, because currently statically assigned virtual
+IRQ 13 for performance counters is not claimed during the initialization
+of MIPS PMU during the bootup, so the IRQ subsystem doesn't know, that
+this interrupt isn't available for further use.
+
+So this patch fixes the issue by simply booking hardware IRQ 5 for MIPS PMU.

+
+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.

+
+The cause is spi_gpio_setup() did not check if the spi-gpio has chipselect pins
+before setting their direction and results in derefing an invalid pointer.
+
+The bug is spotted in kernel 4.19.72 on OpenWrt, and does not occur in 4.14.
+
+There is a similar fix upstream 249e2632dcd0509b8f8f296f5aabf4d48dfd6da8.

+Subject: [RFC PATCH v4 2/2] MIPS: make FPU emulator optional
+
+This small patch makes the MIPS FPU emulator optional. The kernel
+kills float-users on systems without a hardware FPU by sending a SIGILL.
+
+Disabling the emulator shrinks vmlinux by about 54kBytes (32bit,
+optimizing for size).
+
+Signed-off-by: Manuel Lauss <manuel.lauss@gmail.com>
+---
+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.

+Subject: [PATCH] MIPS: Add CPU option reporting to /proc/cpuinfo
+
+Many MIPS CPUs have optional CPU features which are not activates for
+all CPU cores. Print the CPU options which are implemented in the core
+in /proc/cpuinfo. This makes it possible to see what features are
+supported and which are not supported. This should cover all standard
+MIPS extensions, before it only printed information about the main MIPS
+ASEs.

+Subject: [PATCH] arc add OWRTDTB section
+
+This change allows OpenWRT to patch resulting kernel binary with
+external .dtb.
+
+That allows us to re-use exactky the same vmlinux on different boards
+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.

+Subject: [PATCH 1/3] MIPS: Compile post DMA flush only when needed
+
+dma_sync_phys() is only called for some CPUs when a mapping is removed.
+Add ARCH_HAS_SYNC_DMA_FOR_CPU only for the CPUs listed in
+cpu_needs_post_dma_flush() which need this extra call and do not compile
+this code in for other CPUs. We need this for R10000, R12000, BMIPS5000
+CPUs and CPUs supporting MAAR which was introduced in MIPS32r5.
+
+This will hopefully improve the performance of the not affected devices.

++	  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
++	  register MTD 'partitions' corresponding to each image detected,
++	  enable this option.
++
++	  You will still need the parsing functions to be called by the driver
++	  for your particular device. It won't happen automatically.

+on some platforms, erase suspend leads to data corruption and lockups when write

+rather than play whack-a-mole with a hard to reproduce issue on a variety of devices,

+Subject: [PATCH] mtd: spi-nor: support limiting 4K sectors support based on
+ flash size
+
+Some devices need 4K sectors to be able to deal with small flash chips.
+For instance, w25x05 is 64 KiB in size, and without 4K sectors, the
+entire chip is just one erase block.
+On bigger flash chip sizes, using 4K sectors can significantly slow down
+many operations, including using a writable filesystem. There are several
+platforms where it makes sense to use a single kernel on both kinds of
+devices.
+
+To support this properly, allow configuring an upper flash chip size
+limit for 4K sectors support.

+Subject: [PATCH 497/497] mtd: mtdconcat: add dt driver for concat devices
+
+Some mtd drivers like physmap variants have support for concatenating
+multiple mtd devices, but there is no generic way to define such a
+concat device from within the device tree.
+
+This is useful for some SoC boards that use multiple flash chips as
+memory banks of a single mtd device, with partitions spanning chip
+borders.
+
+This commit adds a driver for creating virtual mtd-concat devices. They
+must have a compatible = "mtd-concat" line, and define a list of devices
+to concat in the 'devices' property, for example:
+
+flash {
+  compatible = "mtd-concat";
+
+  devices = <&flash0 &flash1>;
+
+  partitions {
+    ...
+  };
+};
+
+The driver is added to the very end of the mtd Makefile to increase the
+likelyhood of all child devices already being loaded at the time of
+probing, preventing unnecessary deferred probes.

+Subject: ubifs: Add option to create UBI FS version 4 on empty UBI volume
+
+Instead of creating an ubifs file system with format version 5 by
+default on empty UBI volumes add a compile option to create an older ubi
+with file system format version 4 instated. This allows it to be mount
+as a volume on kernel versions < 4.10, which does not support format
+version 5.
+We saw that some people can not access their older data when they
+downgraded from kernel 4.14 to kernel 4.9 to prevent this this option
+would help.

+Subject: [PATCH] net_sched/codel: do not defer queue length update
+
+When codel wants to drop last packet in ->dequeue() it cannot call
+qdisc_tree_reduce_backlog() right away - it will notify parent qdisc
+about zero qlen and HTB/HFSC will deactivate class. The same class will
+be deactivated second time by caller of ->dequeue(). Currently codel and
+fq_codel defer update. This triggers warning in HFSC when it's qlen != 0
+but there is no active classes.
+
+This patch update parent queue length immediately: just temporary increase
+qlen around qdisc_tree_reduce_backlog() to prevent first class deactivation
+if we have skb to return.
+
+This might open another problem in HFSC - now operation peek could fail and
+deactivate parent class.

+Subject: [PATCH] netfilter: nf_flow_table: add hardware offload support
+
+This patch adds the infrastructure to offload flows to hardware, in case
+the nic/switch comes with built-in flow tables capabilities.
+
+If the hardware comes with no hardware flow tables or they have
+limitations in terms of features, the existing infrastructure falls back
+to the software flow table implementation.
+
+The software flow table garbage collector skips entries that resides in
+the hardware, so the hardware will be responsible for releasing this
+flow table entry too via flow_offload_dead().
+
+Hardware configuration, either to add or to delete entries, is done from
+the hardware offload workqueue, to ensure this is done from user context
+given that we may sleep when grabbing the mdio mutex.

+Subject: [PATCH] netfilter: nf_flow_table: support hw offload through
+ virtual interfaces
+
+There are hardware offload devices that support offloading VLANs and
+PPPoE devices. Additionally, it is useful to be able to offload packets
+routed through bridge interfaces as well.
+Add support for finding the path to the offload device through these
+virtual interfaces, while collecting useful parameters for the offload
+device, like VLAN ID/protocol, PPPoE session and Ethernet MAC address.

+Subject: [PATCH] netfilter: nf_flow_table: rework hardware offload timeout
+ handling
+
+Some offload implementations send keepalive packets + explicit
+notifications of TCP FIN/RST packets. In this case it is more convenient
+to simply let the driver update flow->timeout handling and use the
+regular flow offload gc step.
+
+For drivers that manage their own lifetime, a separate flag can be set
+to avoid gc timeouts.

+Subject: 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.

+From: Jonas Gorski <jogo@openwrt.org>
+Subject: ipv6: allow rejecting with "source address failed policy"
+
+RFC6204 L-14 requires rejecting traffic from invalid addresses with
+ICMPv6 Destination Unreachable, Code 5 (Source address failed ingress/
+egress policy) on the LAN side, so add an appropriate rule for that.

+Subject: net: provide defines for _POLICY_FAILED until all code is updated
+
+Upstream introduced ICMPV6_POLICY_FAIL for code 5 of destination
+unreachable, conflicting with our name.
+
+Add appropriate defines to allow our code to build with the new
+name until we have updated our local patches for older kernels

+Many embedded devices have information such as mac addresses stored inside mtd

+Subject: [PATCH 643/660] net: sfp: remove incomplete 100BASE-FX and 100BASE-LX
+ support
+
+The 100BASE-FX and 100BASE-LX support assumes a PHY is present; this
+is probably an incorrect assumption. In any case, sfp_parse_support()
+will fail such a module. Let's stop pretending we support these
+modules.

+Subject: [PATCH 646/660] net: sfp: add module start/stop upstream
+ notifications
+
+When dealing with some copper modules, we can't positively know the
+module capabilities are until we have probed the PHY. Without the full
+capabilities, we may end up failing a module that we could otherwise
+drive with a restricted set of capabilities.
+
+An example of this would be a module with a NBASE-T PHY plugged into
+a host that supports phy interface modes 2500BASE-X and SGMII. The
+PHY supports 10GBASE-R, 5000BASE-X, 2500BASE-X, SGMII interface modes,
+which means a subset of the capabilities are compatible with the host.
+
+However, reading the module EEPROM leads us to believe that the module
+only supports ethtool link mode 10GBASE-T, which is incompatible with
+the host - and thus results in the module being rejected.
+
+This patch adds an extra notification which are triggered after the
+SFP module's PHY probe, and a corresponding notification just before
+the PHY is removed.

+Move phy_start() and phy_stop() into the module_start and module_stop
+notifications in phylink, rather than having them in the SFP code.
+This gives phylink responsibility for controlling the PHY, rather
+than having SFP start and stop the PHY state machine.

+Some SFP+ modules have Clause 45 PHYs embedded on them, which need a

+With Clause 22 PHYs, we assumed that they would operate in SGMII mode,

+Subject: [PATCH 651/660] net: phylink: split link_an_mode configured and
+ current settings
+
+Split link_an_mode between the configured setting and the current
+operating setting.  This is an important distinction to make when we
+need to configure PHY mode for a plugged SFP+ module that does not
+use in-band signalling.

+Subject: [PATCH 653/660] net: phylink: delay MAC configuration for copper SFP
+ modules
+
+Knowing whether we need to delay the MAC configuration because a module
+may have a PHY is useful to phylink to allow NBASE-T modules to work on
+systems supporting no more than 2.5G speeds.
+
+This commit allows us to delay such configuration until after the PHY
+has been probed by recording the parsed capabilities, and if the module
+may have a PHY, doing no more until the module_start() notification is
+called.  At that point, we either have a PHY, or we don't.
+
+We move the PHY-based setup a little later, and use the PHYs support
+capabilities rather than the EEPROM parsed capabilities to determine
+whether we can support the PHY.

+Subject: [PATCH 654/660] net: phylink: make Broadcom BCM84881 based SFPs work
+
+The Broadcom BCM84881 does not appear to send the SGMII control word
+when operating in SGMII mode, which causes network adapters to fail
+to link with the PHY, or decide to operate at fixed 1G speed, even if
+the PHY negotiated 100M.
+
+Work around this by detecting the Broadcom BCM84881 and switch to phy
+mode rather than inband mode.

+Subject: [PATCH 656/660] net: sfp: add support for Clause 45 PHYs
+
+Some SFP+ modules have a Clause 45 PHY onboard, which is accessible via
+the normal I2C address.  Detect 10G BASE-T PHYs which may have an
+accessible PHY and probe for it.

+Subject: [PATCH] bcma: get SoC device struct & copy its DMA params to the
+ subdevices
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+For bus devices to be fully usable it's required to set their DMA
+parameters.
+
+For years it has been missing and remained unnoticed because of
+mips_dma_alloc_coherent() silently handling the empty coherent_dma_mask.
+Kernel 4.19 came with a lot of DMA changes and caused a regression on
+the bcm47xx. Starting with the commit f8c55dc6e828 ("MIPS: use generic
+dma noncoherent ops for simple noncoherent platforms") DMA coherent
+allocations just fail. Example:
+[    1.114914] bgmac_bcma bcma0:2: Allocation of TX ring 0x200 failed
+[    1.121215] bgmac_bcma bcma0:2: Unable to alloc memory for DMA
+[    1.127626] bgmac_bcma: probe of bcma0:2 failed with error -12
+[    1.133838] bgmac_bcma: Broadcom 47xx GBit MAC driver loaded
+
+This change fixes above regression in addition to the MIPS bcm47xx
+commit 321c46b91550 ("MIPS: BCM47XX: Setup struct device for the SoC").
+
+It also fixes another *old* GPIO regression caused by a parent pointing
+to the NULL:
+[    0.157054] missing gpiochip .dev parent pointer
+[    0.157287] bcma: bus0: Error registering GPIO driver: -22
+introduced by the commit 74f4e0cc6108 ("bcma: switch GPIO portions to
+use GPIOLIB_IRQCHIP").
+
+Fixes: f8c55dc6e828 ("MIPS: use generic dma noncoherent ops for simple noncoherent platforms")
