Merge tag 'stable/for-linus-3.6-rc6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen
Pull Xen bug-fixes from Konrad Rzeszutek Wilk:
- Fix M2P batching re-using the incorrect structure field.
In v3.5 we added batching for M2P override (Machine Frame Number ->
Physical Frame Number), but the original MFN was saved in an
incorrect structure - and we would oops/restore when restoring with
the old MFN.
- Disable BIOS SMP MP table search.
A bootup issue that we had ignored until we found that on DL380 G6 it
was needed.
