Justin T. Gibbs 566a5f5020 Merge Xen PVHVM support into the GENERIC kernel config for both
amd64 and i386.

sys/amd64/amd64/mp_machdep.c:
sys/amd64/include/cpu.h:
sys/i386/i386/mp_machdep.c:
sys/i386/include/cpu.h:
	- Introduce two new CPU hooks for initialization and resume
	  purposes. This allows us to get rid of the XENHVM ifdefs in
	  mp_machdep, and also sets some hooks into common code that can be
	  used by other hypervisor implementations.

sys/amd64/conf/XENHVM:
sys/i386/conf/XENHVM:
	- Remove these configs now that GENERIC has builtin support for Xen
	  HVM.

sys/kern/subr_smp.c:
	- Make sure there are no pending IPIs when suspending a system.

sys/x86/xen/hvm.c:
	- Add cpu init and resume vectors that are called from mp_machdep
	  using the new hooks.
	- Only clear the vcpu_info mapping data on resume.  It is already
	  clear for the BSP on a cold boot and is set correctly as APs
	  are started.
	- Gate xen_hvm_init_cpu only to systems running under Xen.

sys/x86/xen/xen_intr.c:
	 - Gate the setup of event channels only to systems running under Xen.
