[Xen-devel] [PATCH 0/8] xen/arm: Handle correctly foreign mapping


This patch series aims to fix "Failed to unmap" message in dom0 when a guest
is creating. Actually it will result to leak dom0 memory.

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.

Sincerely yours,
