[IA64] Fix SMP-unsafe with XENMEM_add_to_physmap on HVM
XENMEM_add_to_physmap hypercall on HVM is SMP-unsafe
and may cause a xen crash.
Actually I've met:
(XEN) ia64_fault, vector=0x18, ifa=0xe0000165c98814f0, iip=0xf0000000040a1b80, ipsr=0x0000121008226010, isr=0x0000008000000030
(XEN) General Exception: IA-64 Reserved Register/Field fault (data access).
...
(XEN) ****************************************
(XEN) Panic on CPU 2:
(XEN) Fault in Xen.
