[Xen-devel] [PATCH 09/15] xen: arm: stub page_is_ram_type.

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

Callers are VT-d (so x86 specific) and various bits of page offlining
support, which although it looks generic (and is in xen/common) does
things like diving into page_info->count_info which is not generic.

In any case on this is only reachable via XEN_SYSCTL_page_offline_op,
which clearly shouldn't be called on ARM just yet.
