[Xen-devel] [PATCh][VT] do_block upon hlt instruction

["Nakajima, Jun" <jun.nakajima@xxxxxxxxx>]

This patch fixes a bug where raise_softirq(SCHEDULE_SOFTIRQ) is called
upon a hlt instruction from a VMX guest, causing repeated VMExits when
the guest is idle. At the same time, it disables the monitor/mwait
feature as it's not feasible to implement for vcpu.
