Hi all,
In the final build today's linux-next build (powerpc allnoconfig) failed
like this:
/tmp/next/build/lib/vdso/gettimeofday.c: In function '__cvdso_clock_gettime_common':
/tmp/next/build/lib/vdso/gettimeofday.c:288:31: error: implicit declaration of function 'BITS_PER_TYPE'; did you mean 'BITS_PER_LONG'? [-Wimplicit-function-declaration]
288 | BUILD_BUG_ON(clock >= BITS_PER_TYPE(msk));

Caused by commit
ca46a07c4b682 (vdso/gettimeofday: Assert that the clockid fits into the u32 bitmask)
I reverted that commit for today.
