Merge tag 'asm-generic-4.6' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic

Pull asm-generic updates from Arnd Bergmann:
 "There are only three patches this time, most other changes to files in
  include/asm-generic tend to go through the tree of whoever depends on
  the change.

  Two patches are cleanups for stuff that is no longer needed, the main
  change is to adapt the generic version of BUG_ON() for CONFIG_BUG=n to
  make it behave consistently with BUG().

  This avoids undefined behavior along with a number of warnings about
  that undefined behavior in randconfig builds when we keep going on
  after hitting a BUG_ON()"
