Upstream in commit 3e3904125fcc ("arm64: Mitigate spectre style branch
history side channels") introduced new config symbol
MITIGATE_SPECTRE_BRANCH_HISTORY which I missed in commit d39a6c67dcb4
("kernel: bump 4.14 to 4.14.275") and buildworkers for arm64 targets
started complaining:
Mitigate Spectre style attacks against branch history (MITIGATE_SPECTRE_BRANCH_HISTORY) [Y/n/?] (NEW) aborted!

Added new config symbol `HARDEN_BRANCH_HISTORY` in order to harden
Spectre style attacks against branch history and fixed rejects in
following patches:

This will reduce the size of the kernel if CONFIG_CC_OPTIMIZE_FOR_SIZE is
set like for all targets with small_flash feature flag.
I haven't seen any changes for an ARM64 target which optimizes the
kernel for speed instead.

3.2% and the compressed kernel size by 2.1%

This removes support for executing old 32 bit applications on 64 bit ARM
and MIPS kernels.
On OpenWrt we normally compile all the user space applications on our
own and do not support third party binary only modules especial not 32
bit applications on 64 bit CPUs.
This reduces the attack surface on such systems and should also save
some memory.

Enable the built-in BPF JIT compiler for all 4.9, 4.14 and 4.19 kernels,
which should speed up cBPF and eBPF-based packet filtering (tc, iptables)
and packet sniffing (libpcap, tcpdump, fwknopd, etc).
This has minimal kernel size impact, increasing the size of uImage-lzma
(normally ~2 MB on mips_24kc or mips64el_mips64) by 5 KB for the MIPS32
arch cBPF JIT and by 9 KB for the MIPS64 arch eBPF JIT, on kernel 4.14.
With JIT enabled (cBPF only), the standard BPF test module (test_bpf.ko)
running on a DIR-835 (mips_24kc) used 33 CPU seconds, but 68 without JIT.
This change aligns with the notion of OpenWRT as the network go-to swiss
army knife for packet handling, especially on CPU-constrained platforms.

This allows us to use the bridge as a managed switch and gracefully
handle mixed tagged and untagged frames. Prior to this, the only
alternative was creating one bridge per vlan which quickly becomes a
nightmare and still won't let you mix both tagged and untagged frames on
the physical port without some complex ebtables magic.
This is in line with the notion that OpenWRT is the network go-to swiss
army knife when you need a nice set-and-forget, low maintenance box to
handle a specific task.
Current builds of the ip-bridge package already fully support this
feature so the only requirement is enabling the kernel config.
This is disabled by default so existing bridge configurations will not
be affected. This patch only gives the ability to turn it on with an
'ip link' command. If there is interest, I could look into making the
feature accessible via uci configuration.
It causes about 3.1% hit on raw bridging speed, which is relatively
trivial considering that I had to use 300 byte packets to strain the CPU
enough to notice a slowdown at all. The ER8 would chug along at wire
speed otherwise, and that's using only one core. Since the typical
bridge use case on OpenWRT is wireless, I doubt it would be noticeable
at all.

In terms of kernel size, it uses 16KB (6753K vs 6737K on ER8) so a
0.002% hit. The exact 16KB is probably just due to how the kernel is
compressed.

Avoid repeating them in the target config, they are overwritten by
top-level menuconfig anyway

Compaction is the only memory management component to form high order (larger
physically contiguous) memory blocks reliably. The page allocator relies on
compaction heavily and the lack of the feature can lead to unexpected OOM
killer invocations for high order memory requests. You shouldn't disable this
option unless there really is a strong reason for it.

Optimized inlining was disabled by default when gcc 4 was still
relatively new. By now, all gcc versions handle this well and there
seems to be no real reason to keep it x86-only.

This adds some configuration options which are selectable when the
layerscape armv7 target is compiled.

Extend the small_flash feature to disable swap, core dumps, and
kernel debug info, and change the squashfs block size to 1024KiB.
Also change squashfs fragment cache to 2 for small_flash to ease memory
usage.

Add a new config option to allow to select the default compile
optimization level for the kernel.
Select the optimization for size by default if the small_flash feature is
set. Otherwise "Optimize for performance" is set.
Add the small_flash feature flag to all (sub)targets which had the
optimization for size in their default kernel config.
Remove CC_OPTIMIZE_FOR_* symbols from all kernel configs to apply the new
setting.
Exceptions to the above are:
- lantiq, where the optimization for size is only required for the
xway_legacy subtarget but was set for the whole target
- mediatek, ramips/mt7620 & ramips/mt76x8 where boards should have
plenty of space and an optimization for size doesn't make much sense
- rb532, which has 128MByte flash

CONFIG_USB_MTU3 is not visible for the mediatek target by default, but
only when CONFIG_USB_GADGET is set. This will config option will be
remove with when running "make kernel_oldconfig", move this option to
the generic config to prevent this.
This fixes the build of the mt7623 subtarget of the mediatek target.
