[PATCH] x86: implement always-locked bit ops, for memory shared with an SMP hypervisor
Add "always lock'd" implementations of set_bit, clear_bit and change_bit and
the corresponding test_and_ functions. Also add "always lock'd"
implementation of cmpxchg. These give guaranteed strong synchronisation and
are required for non-SMP kernels running on an SMP hypervisor.
