6db454e9b6 kernel: Activate CONFIG_OPTIMIZE_INLINING
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.

On the ath79/tiny target the uncompressed kernel size was reduced by
3.2% and the compressed kernel size by 2.1%

1362051 build_dir/target-mips_24kc_musl/linux-ath79_tiny/tplink_tl-wr941-v4-kernel.bin

This change is currently pending for kernel 5.2 and already in
linux-next, this updates our patch to match the upstream version.

46af22de16 kernel: Remove CONFIG_COMPAT

a7370b5179 kernel: enable CONFIG_BPF_JIT by default
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.

51c094e703 kernel: enable CONFIG_BRIDGE_VLAN_FILTERING
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.

Add a new config option to allow to select the default compile

Select the optimization for size by default if the small_flash feature is

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

da6c09eff4 kernel: move CONFIG_USB_MTU3 to generic config
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.
