The 'vp_assist' page is currently an example of a guest page which needs to be kept mapped throughout the life-time of a guest, but there are other such examples in the specifiction [1]. This patch therefore introduces a generic 'viridian_page' type and converts the current vp_assist/apic_assist related code to use it. Subsequent patches implementing other enlightments can then also make use of it. This patch also renames the 'vp_assist_pending' field in struct hvm_viridian_vcpu_context to 'apic_assist_pending' to more accurately reflect its meaning. The term 'vp_assist' applies to the whole page rather than just the EOI-avoidance enlightenment. New versons of the specification have defined data structures for other enlightenments within the same page. No functional change.
