Kernel v5.1 included an eBPF JIT for MIPS32 kernels, but problems were
discovered [1] and the changes later reverted in kernel v5.5 with commits:
* f8fffebdea75 ("MIPS: BPF: Disable MIPS32 eBPF JIT")
* 36366e367ee9 ("MIPS: BPF: Restore MIPS32 cBPF JIT")
Only the first of these was backported to LTS kernel 5.4, leaving cBPF
programs without a JIT and introducing a performance regression for any
such users e.g. libpcap, tcpdump, etc.
Restore cBPF performance by backporting the second commit above:
* 070-v5.5-MIPS-BPF-Restore-MIPS32-cBPF-JIT.patch

This patch adds cpu frequency setting for AR724x and AR7161.
It is unknown if all the AR71xx devices support the same value range,
so support is only enabled for AR7161 at this stage.

The current code would return an error on ath79 when the SoC isn't known
to the driver. Return the raw hex value instead, as happens with non
supported targets.
Also return the correctly incremented value from
sc_tag_cpufreq_ath79_arraysize()

RouterBOOT cpu frequency settings are letter-indexed. Follow the
same logic for the sysfs interface.

The "mtd: rawnand: Pass a nand_chip object to nand_release()" commit was
backported which needed some adaptations to other code.

This resolves a hazard between a mtc0 and a mfc0 instruction after
activating the DSP support. Without this fix the CPU could use the old
value again and the DSP support would not be active.

From upstream:
b8392808eb3f sch_cake: add RFC 8622 LE PHB support to CAKE diffserv handling
3f608f0c4136 sch_cake: fix a few style nits
8c95eca0bb8c sch_cake: don't call diffserv parsing code when it is not needed
9208d2863ac6 sch_cake: don't try to reallocate or unshare skb unconditionally
From netdev not yet accepted:
sch_cake: fix IP protocol handling in the presence of VLAN tags
The VLAN tag handling is actually wider than just cake so upstream are
working out how to fix it generically. We fix it here just for cake.

This was backported to 4.19 and I clearly expected it to land in 5.4 but
it didn't (5.5) so backport it to 5.4 for consistency.
