Merge tag 'stable/for-linus-3.6-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen
Pull Xen bug-fixes from Konrad Rzeszutek Wilk:
* Fix for TLB flushing introduced in v3.6
* Fix Xen-SWIOTLB not using proper DMA mask - device had 64bit but
in a 32-bit kernel we need to allocate for coherent pages from a
32-bit pool.
* When trying to re-use P2M nodes we had a one-off error and triggered
a BUG_ON check with specific CONFIG_ option.
* When doing FLR in Xen-PCI-backend we would first do FLR then save the
PCI configuration space. We needed to do it the other way around.
* tag 'stable/for-linus-3.6-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen:
xen/pciback: Fix proper FLR steps.
xen: Use correct masking in xen_swiotlb_alloc_coherent.
xen: fix logical error in tlb flushing
xen/p2m: Fix one-off error in checking the P2M tree directory.
