Merge tag 'stable/for-linus-3.4-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen
Pull xen fixes from Konrad Rzeszutek Wilk:
- mechanism to work with misconfigured backends (where they are
advertised but in reality don't exist).
- two tiny compile warning fixes.
- proper error handling in gnttab_resume
- Not using VM_PFNMAP anymore to allow backends in the same domain.
* tag 'stable/for-linus-3.4-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen:
Revert "xen/p2m: m2p_find_override: use list_for_each_entry_safe"
xen/resume: Fix compile warnings.
xen/xenbus: Add quirk to deal with misconfigured backends.
xen/blkback: Fix warning error.
xen/p2m: m2p_find_override: use list_for_each_entry_safe
xen/gntdev: do not set VM_PFNMAP
xen/grant-table: add error-handling code on failure of gnttab_resume
