Subject: [GIT PULL] bitmap for 6.18

Hi Linus,

Please pull bitmap patches for 6.18:
 - almost complete consolidation for HIWORD_UPDATE()-like macros from Nicolas;
 - bitmaps wrapper for Rust from Burak together with dynamic ID pool based on
   it and  tests;
 - __fls() fix for arc from Kees.

The patches spent for over 2 weeks in -next with no issues.

Thanks,
Yury
