Merge tag 'asm-generic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
Pull asm-generic updates from Arnd Bergmann:
"The asm-generic tree this time contains one series from Nicolas Pitre
that makes the optimized do_div() implementation from the ARM
architecture available to all architectures.
This also adds stricter type checking for callers of do_div, which has
uncovered a number of bugs in existing code, and fixes up the ones we
have found"
