The raid5 xor checksums use MMX/SSE state and are not preempt-safe.

Attached patch disables preemption in FPU_SAVE and XMMS_SAVE and
restores it in FPU_RESTORE and XMMS_RESTORE - preventing preemption
while in fp mode.

Neither lockd nor rpciod properly drop the BKL on exit.

Yes, the BKL is automatically relinquished on schedule but the failure
to drop the lock throws off the atomic accounting and results in a
preempt_count warning on exit.

This makes them play fair - it does not hurt.

DaveM noticed he needed a pci_dma_sync_single() after the
DMA conversion late in 32 ; here's the patch.

FYI this driver was previously having to unmap/remap in
that location, this is an improvement!  :)
