kernel/include/asm-generic/bitops/count_zeros.h, branch linux-4.3.yHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-4.3.y2012-10-08T03:20:11ZMPILIB: Provide count_leading/trailing_zeros() based on arch functions2012-10-08T03:20:11ZDavid Howellsdhowells@redhat.com2012-09-13T12:09:33Zurn:sha1:aacf29bf1bf133f6219e6f8969d4ebc2ac76458f
Provide count_leading/trailing_zeros() macros based on extant arch bit scanning
functions rather than reimplementing from scratch in MPILIB.
Whilst we're at it, turn count_foo_zeros(n, x) into n = count_foo_zeros(x).
Also move the definition to asm-generic as other people may be interested in
using it.
