Linus,
Please pull the siginfo-linus branch from the git tree:
git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git siginfo-linus
HEAD: f6a015498dcaee72f80283cb7873d88deb07129c signal/x86: Include the field offsets in the build time checks
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.
Eric W. Biederman (2): signal: Correct the offset of si_pkey in struct siginfo signal/x86: Include the field offsets in the build time checks
