Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 fixes from Thoma Gleixner:
 "Another round of fixes for x86:

   - Move the initialization of the microcode driver to late_initcall to
     make sure everything that init function needs is available.

   - Make sure that lockdep knows about interrupts being off in the
     entry code before calling into c-code.

   - Undo the cpu hotplug init delay regression.

   - Use the proper conditionals in the mpx instruction decoder.

   - Fixup restart_syscall for x32 tasks.

   - Fix the hugepage regression on PAE kernels which was introduced
     with the latest PAT changes"
