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
