  cpumask: fix checking valid cpu range (2022-10-01 10:22:58 -0700)

----------------------------------------------------------------
bitmap patches for v6.1-rc1

Hi Linus,

Please pull this patches. They spent more than a week in -next without
major problems. The only problem with warnings generated by cpumask_check(),
when robots do bisection, is fixed by moving the patch "cpumask: fix
checking valid cpu range" to the very end of the series.

Also, it looks like Phil's patch is already in master, merged through
Greg's tree.

Thanks,
Yury

This branch is based on v6.0-rc4 and includes:
