x86, hvm: Hyper-V guest interface support with small set of enlightenments
A minimal implementation of the Viridian (Hyper-V) guest
interface. The only enlightenments advertised and supported are vAPIC
MSRs and long-spin-wait notifications. The set of enlightenments can
easily be extended in future, as they are found to provide a
performance win, and configured via an extended HVM_PARAM_VIRIDIAN hvm
parameter.
