[Xen-devel] [PATCH for-3.2 v3 04/14] accel: register global_props like machine globals

[Marc-André Lureau <marcandre.lureau@xxxxxxxxxx>]

global_props is only used for Xen xen_compat_props. It's a static
array of GlobalProperty, like machine globals in SET_MACHINE_COMPAT().
Let's register the globals the same way, without extra copy allocation.
