Roger Pau Monne 4cd44fd345 x86/xen: attempt to inflate the memory balloon on PVH 
[ Upstream commit 38620fc4e8 ]

When running as PVH or HVM Linux will use holes in the memory map as scratch
space to map grants, foreign domain pages and possibly miscellaneous other
stuff.  However the usage of such memory map holes for Xen purposes can be
problematic.  The request of holesby Xen happen quite early in the kernel boot
process (grant table setup already uses scratch map space), and it's possible
that by then not all devices have reclaimed their MMIO space.  It's not
unlikely for chunks of Xen scratch map space to end up using PCI bridge MMIO
window memory, which (as expected) causes quite a lot of issues in the system.

At least for PVH dom0 we have the possibility of using regions marked as
UNUSABLE in the e820 memory map.  Either if the region is UNUSABLE in the
native memory map, or it has been converted into UNUSABLE in order to hide RAM
regions from dom0, the second stage translation page-tables can populate those
areas without issues.

PV already has this kind of logic, where the balloon driver is inflated at
boot.  Re-use the current logic in order to also inflate it when running as
PVH.  onvert UNUSABLE regions up to the ratio specified in EXTRA_MEM_RATIO to
RAM, while reserving them using xen_add_extra_mem() (which is also moved so
it's no longer tied to CONFIG_PV).

[jgross: fixed build for CONFIG_PVH without CONFIG_XEN_PVH]
