Merge tag 'stable/for-linus-3.6-rc1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen
Pull Xen fix from Konrad Rzeszutek Wilk: "Way back in v3.5 we added a mechanism to populate back pages that were released (they overlapped with MMIO regions), but neglected to reserve the proper amount of virtual space for extend_brk to work properly. Coincidentally some other commit aligned the _brk space to larger area so I didn't trigger this until it was run on a machine with more than 2GB of MMIO space." * On machines with large MMIO/PCI E820 spaces we fail to boot b/c we failed to pre-allocate large enough virtual space for extend_brk. * tag 'stable/for-linus-3.6-rc1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen: xen/p2m: Reserve 8MB of _brk space for P2M leafs when populating back.
