Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Peter Anvin:
"Two quite small fixes: one a build problem, and the other fixes
seccomp filters on x32."
* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86: Fix rebuild with EFI_STUB enabled
x86: remove the x32 syscall bitmask from syscall_get_nr()
