Merge tag 'for-linus-4.5-rc5-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull xen bug fixes from David Vrabel: - Two scsiback fixes (resource leak and spurious warning). - Fix DMA mapping of compound pages on arm/arm64. - Fix some pciback regressions in MSI-X handling. - Fix a pcifront crash due to some uninitialize state. * tag 'for-linus-4.5-rc5-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: xen/pcifront: Fix mysterious crashes when NUMA locality information was extracted. xen/pcifront: Report the errors better. xen/pciback: Save the number of MSI-X entries to be copied later. xen/pciback: Check PF instead of VF for PCI_COMMAND_MEMORY xen: fix potential integer overflow in queue_reply xen/arm: correctly handle DMA mapping of compound pages xen/scsiback: avoid warnings when adding multiple LUNs to a domain xen/scsiback: correct frontend counting
