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

Pull asm-generic uaccess.h cleanup from Arnd Bergmann:
 "Like in 3.19, I once more have a multi-stage cleanup for one
  asm-generic header file, this time the work was done by Michael
  Tsirkin and cleans up the uaccess.h file in asm-generic, as well as
  all architectures for which the respective maintainers did not pick up
  his patches directly"
