[Xen-devel] [PATCH 3/7] libxenlight resend: 8mb physmap slack for pv domains



Contemplate 8MB of slack for PV domains, since they
do ballooning (or flipping network rx) and need
some extra room in their pfn space.

Note that this does not allocate any extra memory
to the domain, it simply extends the physmap with
some extra room for "bounce bufffering back" pfn's
that are yielded to dom0.
