Merge tag 'stable/for-linus-3.8-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen
Pull Xen fixes from Konrad Rzeszutek Wilk:
- CVE-2013-0190/XSA-40 (or stack corruption for 32-bit PV kernels)
- Fix racy vma access spotted by Al Viro
- Fix mmap batch ioctl potentially resulting in large O(n) page allcations.
- Fix vcpu online/offline BUG:scheduling while atomic..
- Fix unbound buffer scanning for more than 32 vCPUs.
- Fix grant table being incorrectly initialized
- Fix incorrect check in pciback
- Allow privcmd in backend domains.
Fix up whitespace conflict due to ugly merge resolution in Xen tree in
arch/arm/xen/enlighten.c
