Merge tag 'asm-generic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git...

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"
