This series aims to prevent PVH Dom0 from accessing MMIO regions of
devices that are used by Xen.
I know there are concerns with the way we build a PVH Dom0 right now, but
addressing those requires a major rework of how construct_dom0 works. IMHO I
don't think this should block this series,
Prevent Dom0 from accessing HPET MMIO region by adding the HPET mfn to the
list of forbiden memory regions (if ACPI_HPET_PAGE_PROTECT4 or
ACPI_HPET_PAGE_PROTECT64 flag is set) or to the list of read-only regions.
Also provide an option that prevents adding the HPET to the read-only memory
regions
Check that MMIO regions added to PVH Dom0 are allowed. Previously a PVH Dom0
would have access to the full MMIO range.

Xen has support for splitting heavy work work into a series
of hypercalls, called multicalls, and preempting them through
what Xen calls continuation [0]. Despite this though without

Use gnttab_unmap_refs_async() to wait until the mapped pages are no
longer in use before unmapping them.
This allows blkback to use network storage which may retain refs to

For one, the problem goes away to
xen_get_vmport_regs_pfn should take a xen_pfn_t argument, not an
unsigned long argument (in fact xen_pfn_t is defined as uint64_t on
ARM).
Also use xc_hvm_param_get instead of the deprecated xc_get_hvm_param.
