Subject[GIT PULL] xen: features and fixes for 3.19-rc0
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Linus,

Please git pull the following tag:

git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip.git stable/for-linus-3.19-rc0-tag

xen: features and fixes for 3.19-rc0

- - 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.

Thanks.

David
