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"
