[GIT PULL] bitmap for 7.1

[Yury Norov]

Hi Linus,

Please pull bitmap/bitops updates for v7.1-rc1.

This includes two new helpers, tests improvements and new tests, the
API usage cleanups, and random comments and docs fixes.

All patches spent in -next for at least 2 weeks with no issues.

Thanks,
Yury
