[PATCH v7 00/14] 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.

I pushed a branch with this series applied on top of staging:
git://xenbits.xen.org/people/julieng/xen-unstable.git branch typesafe-v7

For all the changes see in each patch.

Yours sincerely,
