[RFC 00/14] arm: implement ballooning and privcmd foreign mappings based on x86 PVH
This series implements ballooning for Xen on ARM and builds and Mukesh''s
PVH privcmd stuff to implement foreign page mapping on ARM, replacing
the old "HACK: initial (very hacky) XENMAPSPACE_gmfn_foreign" patch.
The baseline is a bit complex, it is basically Stefano''s xenarm-forlinus
branch (commit bbd6eb29214e) merged with Konrad''s linux-next-pvh branch
