[PATCH RESEND v9 00/14] Implement the XEN_DOMCTL_memory_mapping hypercall for ARM

[Arianna Avanzini <avanzini.arianna@gmail.com>]

Hello,

I have adapted the v9 patchset to work on top of commit 7bddc6b, which I see
as head of the development repository's master branch. The changes with
respect to the original v9 have ultimately affected only patches from 0001 to
0005: I hope I haven't missed anything else, in case of any issue please do
not hesitate to tell me.

Also, please note that this resend patchset does not address any of the
comments made for the original v9; I will be sending a v10 patchset within
the upcoming week. The implementation of this resend patchset is described
in the changelog of each patch and in the original cover letter of v9 ([1]).

The patchset has been tested on a cubieboard2 with Linux 3.15 as dom0 and
both ERIKA Enterprise ([2]) and Linux 3.15 as domU. The x86 bits have been also
tested on an x86_64 machine with Linux 3.15 as both dom0 and domU.

Thank you,
Arianna
