[GIT PULL] Xen fixes

[Jeremy Fitzhardinge <jeremy@goop.org>]

Hi Linus,

Another handful of Xen fixes:

    * Fix a hang-on-shutdown regression introduced by 76fac077db6b34e2
      ("x86, kexec: Make sure to stop all CPUs before exiting the
      kernel") [Also for stable]
    * Fix crash-on-boot regression on 32-bit systems, caused by
      b40827fa7268 ("x86-32, mm: Add an initial page table for core
      bootstrapping")
    * Avoid using memory that's inaccessible on 32-bit systems without
      HIGHMEM
    * Don't assume NUMA node 0 is always present when allocating irq descs
    * Kill Xen's private idle implementation in favour of using default_idle
    * Simplify boot-time E820 mangling, which fixes a couple of corner cases

There are two branches:

  git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git upstream/core

Jeremy Fitzhardinge (4):
      xen: clean up "extra" memory handling some more
      xen: use default_idle
      xen: prevent crashes with non-HIGHMEM 32-bit kernels with largeish memory
      xen: allocate irq descs on any NUMA node
