Merge tag 'stable/for-linus-3.13-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull Xen bug-fixes from Konrad Rzeszutek Wilk: "Fixes to patches that went in this merge window along with a latent bug: - Fix lazy flushing in case m2p override fails. - Fix module compile issues with ARM/Xen - Add missing call to DMA map page for Xen SWIOTLB for ARM" * tag 'stable/for-linus-3.13-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: xen/gnttab: leave lazy MMU mode in the case of a m2p override failure xen/arm: p2m_init and p2m_lock should be static arm/xen: Export phys_to_mach to fix Xen module link errors swiotlb-xen: add missing xen_dma_map_page call
