Merge tag 'ffs-const-v6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull ffs const-attribute cleanups from Kees Cook:
"While working on various hardening refactoring a while back we
encountered inconsistencies in the application of __attribute_const__
on the ffs() family of functions.
This series fixes this across all archs and adds KUnit tests.
Notably, this found a theoretical underflow in PCI (also fixed here)
and uncovered an inefficiency in ARC (fixed in the ARC arch PR). I
kept the series separate from the general hardening PR since it is a
stand-alone "topic".
- PCI: Fix theoretical underflow in use of ffs().
- Universally apply __attribute_const__ to all architecture's
ffs()-family of functions.
- Add KUnit tests for ffs() behavior and const-ness"
