Merge branch 'x86-entry-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 entry updates from Ingo Molnar:
"This contains x32 and compat syscall improvements, the biggest one of
which splits x32 syscalls into their own table, which allows new
syscalls to share the x32 and x86-64 number - which turns the
512-547 special syscall numbers range into a legacy wart that won't be
extended going forward"
* 'x86-entry-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/syscalls: Split the x32 syscalls into their own table
x86/syscalls: Disallow compat entries for all types of 64-bit syscalls
x86/syscalls: Use the compat versions of rt_sigsuspend() and rt_sigprocmask()
x86/syscalls: Make __X32_SYSCALL_BIT be unsigned long
