Merge branch 'x86-asm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git...

Pull x86 user access changes from Ingo Molnar:
 "This tree contains two copy_[from/to]_user() build time checking
  changes/enhancements from Jan Beulich.

  The desired outcome is to get better compiler warnings with
  CONFIG_DEBUG_STRICT_USER_COPY_CHECKS=y, to keep people from
  introducing bugs such as overflows and information leaks"
