  usercopy: Don't use "proxy" headers (2024-05-19 16:12:38 -0700)

bitmap patches for 6.10

Hi Linus,

Please pull patches for 6.10. This includes:
 - topology_span_sane() optimization from Kyle Meyer;
 - fns() rework from Kuan-Wei Chiu (used in
   cpumask_local_spread() and other places); and
 - headers cleanup from Andy.

This also adds a MAINTAINERS record for bitops API as it's unattended,
and I'd like to follow it closer.

v2: drop binary fns().

Thanks,
Yury
