- 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:
