[PATCH v4 00/16] xen/arm: Use the typesafes gfn and mfn

[Julien Grall <julien.grall@arm.com>]

Hello all,

Some of the ARM functions are mixing gfn vs mfn and even physical vs frame.

To avoid more confusion, this patch series makes use of the terminology
described in xen/include/xen/mm.h and the associated typesafe.

This series requires the patch [1] to be applied beforehand. I pushed a
branch with this patch and this series applied on xenbits:
git://xenbits.xen.org/people/julieng/xen-unstable.git branch typesafe-v4

The patches #5 and #8-#18 are brand new, after Stefano requested to push the
gfn/mfn typesafe down to apply_p2m_changes for ARM. It requires some
cleanup/fixes before been able to do the actual rework.

For all the changes see in each patch.

Yours sincerely,
