Re: [Xen-devel] [PATCH v7 7/8] xen/arm: don't iomem_permit_access for reserved-memory regions

Hi Stefano,

Don't allow reserved-memory regions to be remapped into any unprivileged
guests, until reserved-memory regions are properly supported in Xen. For
now, do not call iomem_permit_access on them, because giving
iomem_permit_access to dom0 means that the toolstack will be able to
assign the region to a domU.
