Nothing the kernel needs to touch is swappable. by this point the
suspend process only needs kernel stuff, userland has done running (but
it still schedulnig until we disable interrupts). We don't swap device
softcs etc, for obvious reasons.
Ok, so there is one kernel thing that is swappable: pipe buffers, but
they are not dependant for suspend (see above).
