Merge tag 'stable/for-linus-3.14-rc0-late-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull Xen bugfixes from Konrad Rzeszutek Wilk: "Bug-fixes for the new features that were added during this cycle. There are also two fixes for long-standing issues for which we have a solution: grant-table operations extra work that was not needed causing performance issues and the self balloon code was too aggressive causing OOMs. Details: - Xen ARM couldn't use the new FIFO events - Xen ARM couldn't use the SWIOTLB if compiled as 32-bit with 64-bit PCIe devices. - Grant table were doing needless M2P operations. - Ratchet down the self-balloon code so it won't OOM. - Fix misplaced kfree in Xen PVH error code paths" * tag 'stable/for-linus-3.14-rc0-late-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: xen/pvh: Fix misplaced kfree from xlated_setup_gnttab_pages drivers: xen: deaggressive selfballoon driver xen/grant-table: Avoid m2p_override during mapping xen/gnttab: Use phys_addr_t to describe the grant frame base address xen: swiotlb: handle sizeof(dma_addr_t) != sizeof(phys_addr_t) arm/xen: Initialize event channels earlier
