Merge tag 'stable/for-linus-3.13-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull Xen bugfixes from Konrad Rzeszutek Wilk:
- Fix balloon driver for auto-translate guests (PVHVM, ARM) to not use
scratch pages.
- Fix block API header for ARM32 and ARM64 to have proper layout
- On ARM when mapping guests, stick on PTE_SPECIAL
- When using SWIOTLB under ARM, don't call swiotlb functions twice
- When unmapping guests memory and if we fail, don't return pages which
failed to be unmapped.
- Grant driver was using the wrong address on ARM.
* tag 'stable/for-linus-3.13-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip:
xen/balloon: Seperate the auto-translate logic properly (v2)
xen/block: Correctly define structures in public headers on ARM32 and ARM64
arm: xen: foreign mapping PTEs are special.
xen/arm64: do not call the swiotlb functions twice
xen: privcmd: do not return pages which we have failed to unmap
XEN: Grant table address, xen_hvm_resume_frames, is a phys_addr not a pfn
