      Merge tag 'stable/for-linus-3.7-arm-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen
      Pull ADM Xen support from Konrad Rzeszutek Wilk:
         * Allow a Linux guest to boot as initial domain and as normal guests
           on Xen on ARM (specifically ARMv7 with virtualized extensions).  PV
           console, block and network frontend/backends are working.
         * Fix compile linux-next fallout.
         * Fix PVHVM bootup crashing.
        The Xen-unstable hypervisor (so will be 4.3 in a ~6 months), supports
        ARMv7 platforms.
        The goal in implementing this architecture is to exploit the hardware
        as much as possible.  That means use as little as possible of PV
        operations (so no PV MMU) - and use existing PV drivers for I/Os
        (network, block, console, etc).  This is similar to how PVHVM guests
        operate in X86 platform nowadays - except that on ARM there is no need
        for QEMU.  The end result is that we share a lot of the generic Xen
        drivers and infrastructure.
        Details on how to compile/boot/etc are available at this Wiki:
        and this blog has links to a technical discussion/presentations on the
        overall architecture:
