Generic kernels feed many operation through the "machvec" logic to get
the correct form of the operation for the current system. "mmiowb()" is
one of those operations.
Although machvec is initialized very early in boot, it isn't early
enough for a recent upstream kernel change that added mmiowb to the
spin_unlock() path.
Statically initialize the mmiowb field of machvec so that we won't die
with a call through a NULL pointer. This should be safe because we do
the real initialization of machvec before bringing up any addtional CPUs
or doing any I/O.
