A last-minute, configuration specific issue was discovered with this change which is why it was not included in my previous pull request. This is now been fixed and tested" * tag 'stable/for-linus-3.19-rc0b-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: xen: switch to post-init routines in xen mmu.c earlier Revert "swiotlb-xen: pass dev_addr to swiotlb_tbl_unmap_single" xen: annotate xen_set_identity_and_remap_chunk() with __init xen: introduce helper functions to do safe read and write accesses xen: Speed up set_phys_to_machine() by using read-only mappings xen: switch to linear virtual mapped sparse p2m list xen: Hide get_phys_to_machine() to be able to tune common path x86: Introduce function to get pmd entry pointer xen: Delay invalidating extra memory xen: Delay m2p_override initialization xen: Delay remapping memory of pv-domain xen: use common page allocation function in p2m.c xen: Make functions static xen: fix some style issues in p2m.c
