[Xen-devel] [PATCH v6 00/10] xen/arm: Handle correctly foreign mapping

[Julien Grall <julien.grall@xxxxxxxxxx>]

Hello,

This patch series aims to fix "Failed to unmap" message in dom0 when a guest is
creating. Without this patch series, dom0 will leak memory each time a domain
is created. It should be considered as a blocker for Xen 4.4 release.

    - Patch #1-2: prepare work for the others patches
    - Patch #3-6: add support for p2m type
    - Patch #7-9: handle correctly foreign mapping.
    - Patch #10: it's not really part of this series. It adds support
        for read-only grant-mapping

For all the changes, see in each patch.

Sincerely yours,
Release-acked-by: George Dunlap <george.dunlap@xxxxxxxxxxxxx>
