Linus Torvalds 896ea17d3d Features:
- Add necessary infrastructure to make balloon driver work under ARM.
  - Add /dev/xen/privcmd interfaces to work with ARM and PVH.
  - Improve Xen PCIBack wild-card parsing.
  - Add Xen ACPI PAD (Processor Aggregator) support - so can offline/online
    sockets depending on the power consumption.
  - PVHVM + kexec = use an E820_RESV region for the shared region so we don't
    overwrite said region during kexec reboot.
  - Cleanups, compile fixes.

Merge tag 'stable/for-linus-3.8-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen

Pull Xen updates from Konrad Rzeszutek Wilk:
 - Add necessary infrastructure to make balloon driver work under ARM.
 - Add /dev/xen/privcmd interfaces to work with ARM and PVH.
 - Improve Xen PCIBack wild-card parsing.
 - Add Xen ACPI PAD (Processor Aggregator) support - so can offline/
   online sockets depending on the power consumption.
 - PVHVM + kexec = use an E820_RESV region for the shared region so we
   don't overwrite said region during kexec reboot.
 - Cleanups, compile fixes.

Fix up some trivial conflicts due to the balloon driver now working on
ARM, and there were changes next to the previous work-arounds that are
now gone.

* tag 'stable/for-linus-3.8-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen:
  xen/PVonHVM: fix compile warning in init_hvm_pv_info
  xen: arm: implement remap interfaces needed for privcmd mappings.
  xen: correctly use xen_pfn_t in remap_domain_mfn_range.
  xen: arm: enable balloon driver
  xen: balloon: allow PVMMU interfaces to be compiled out
  xen: privcmd: support autotranslated physmap guests.
  xen: add pages parameter to xen_remap_domain_mfn_range
  xen/acpi: Move the xen_running_on_version_or_later function.
  xen/xenbus: Remove duplicate inclusion of asm/xen/hypervisor.h
  xen/acpi: Fix compile error by missing decleration for xen_domain.
  xen/acpi: revert pad config check in xen_check_mwait
  xen/acpi: ACPI PAD driver
  xen-pciback: reject out of range inputs
  xen-pciback: simplify and tighten parsing of device IDs
  xen PVonHVM: use E820_Reserved area for shared_info
