  bitops/non-atomic: make @nr unsigned to avoid any DIV (2021-08-14
13:07:42 +0200)

----------------------------------------------------------------
asm-generic changes for 5.15

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().
