Here's a few things I wanted to tidy before doing the lazy tlb mm
shootdown / exit TLB flush IPI optimisation. There is no hard
dependency just slight code rearrangement but since we're waiting
for the shootdown patches to go via the -mm tree we could do these
now.

It basically just removing a bunch of dead code, or replacing them
with WARN so we can remove them entirely in a release or two.

Thanks,
Nick
