Build test:
mips (gcc version 11.2.1 20220301): 62 configs -> 3 failures
arm (gcc version 11.2.1 20220301): 100 configs -> no new failure
arm64 (gcc version 11.2.1 20220301): 3 configs -> no failure
x86_64 (gcc version 11.2.1 20220301): 4 configs -> no failure

Mips build failures were reported earlier, and it needs:
e5b40668e93 ("slip: fix macro redefine warning")
b81e0c2372e ("block: drop unused includes in <linux/genhd.h>")

Boot test:
x86_64: Booted on my test laptop. No regression.
x86_64: Booted on qemu. No regression. [1]
arm64: Booted on rpi4b (4GB model). No regression. [2]
mips: Booted on ci20 board. No regression. [3]

Results from Linaro’s test farm.
No test regressions on arm64, arm, x86_64, and i386.

But we found following kernel crash [1] on rpi-4 while running LTP controllers
tests we are in process to reproduce and bisect the issue.
