    Merge branch 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
    
    Pull sigingo fix from Eric Biederman:
     "The kbuild test robot found that I accidentally moved si_pkey when I
      was cleaning up siginfo_t. A short followed by an int with the int
      having 8 byte alignment. Sheesh siginfo_t is a weird structure.
    
      I have now corrected it and added build time checks that with a little
      luck will catch any similar future mistakes. The build time checks
      were sufficient for me to verify the bug and to verify my fix. So they
      are at least useful this once."
    
    * 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace:
      signal/x86: Include the field offsets in the build time checks
