Merge tag 'stable/for-linus-3.19-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull xen features and fixes from David Vrabel:
- Fully support non-coherent devices on ARM by introducing the
mechanisms to request the hypervisor to perform the required cache
maintainance operations.
- A number of pciback bug fixes and cleanups. Notably a deadlock fix
if a PCI device was manually uunbound and a fix for incorrectly
restoring state after a function reset.
- In x86 PVHVM guests, use the APIC for interrupts if this has been
virtualized by the hardware. This reduces the number of interrupt-
related VM exits on such hardware.
