- 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
