Merge tag 'asm-generic-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
Pull asm-generic updates from Arnd Bergmann:
"The main content for 5.15 is a series that cleans up the handling of
strncpy_from_user() and strnlen_user(), removing a lot of slightly
incorrect versions of these in favor of the lib/strn*.c helpers that
implement these correctly and more efficiently.
The only architectures that retain a private version now are mips,
ia64, um and parisc. I had offered to convert those at all, but Thomas
Bogendoerfer wanted to keep the mips version for the moment until he
had a chance to do regression testing.
The branch also contains two patches for bitops and for ffs()"
