Xen devel - Dec 2010 - [GIT PULL] Xen fixes

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

Oh, could you also pull:

  git://xenbits.xen.org/people/sstabellini/linux-pvhvm.git
2.6.37-rc4-pvhvm-fixes

Stefano Stabellini (5):
      xen: use PHYSDEVOP_get_free_pirq to implement find_unbound_pirq
      xen: fix MSI setup and teardown for PV on HVM guests
      xen: resume the pv console for hvm guests too
      xen: fix save/restore for PV on HVM guests with pirq remapping
      xen: unplug the emulated devices at resume time

Which fixes various bugs when running in "fully virtualized +
paravirtualizations" mode:

    * removes the use of a never-implemented experimental Xen ABI, and
      replaces it with the one that did finally get implemented
    * make MSI work on passed-through devices
    * various save/restore fixes (console, interrupts, emulated device
      unplugging)

Thanks,
    J
