expose MWAIT to dom0
There''re basically two methods to enter a given C-state: legacy (hlt + I/O read),
and native(using mwait). MWAIT is always preferred when both underlying CPU
and OS support, which is a more efficient way to conduct C-state transition.
Xen PM relies on Dom0 to parse ACPI Cx/Px information, which involves one
step to notify BIOS about a set of capabilities supported by OSPM. One capability

[PATCH v2 0/5] ARM hypercall ABI: 64 bit ready
Hi all,
this patch series makes the necessary changes to make sure that the
current ARM hypercall ABI can be used as-is on 64 bit ARM platforms:
- it defines xen_ulong_t as uint64_t on ARM;
- it introduces a new macro to handle guest pointers, called
XEN_GUEST_HANDLE_PARAM (that has size 4 bytes on aarch and is going to
have size 8 bytes on aarch64);
- it replaces all the occurrences of
