George: I forgot to add that for the release perspective, this series is a bug fix for Xen 4.4 on ARM. Without this series, dom0 will run out of memory sooner or later.

The series is based on pvh dom0 v5 patch series (http://www.gossamer-threads.com/lists/xen/devel/309493?page=last) from Mukesh. - Patch #1: this patch add support to remove correctly foreign page on ARM, if it's possible I would like to merge with patch #6 of Mukesh. - Patch #2: prepare work for the other patch - Patch #3-6: add support for p2m type - Patch #7: set p2m type for foreign page - Patch #8: it's not really part of this serie. It adds support for read-only grant-mapping. In the ideal world, this patch series and the pvh dom0 series should be mixed to avoid to introduce dummy functions that will be removed later.
