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
