bitkeeper revision 1.1236.1.184 (424d4a00y8MNt89B4nCZ8LKcrTcZUw)
Fix multi-VCPU TLB shootdown interface -- specify pointer to VCPU
bitmap, so it is read at time of flush and not before (which might be
too early, before all updates are flushed, leading to races). Also
add selective multi-VCPU shootdown capability to update_va_mapping()
and use this to make ptep_set_access_flags() a single hypercall.
