I was discussing this with sct a few days back.  iiuc, the proposal
was to create a small per-cpu pool (say, 4-8 pages) which is a
"front-end" to regular old kmap().

Any time you have one of these pages in use, the process gets
pinned onto the current CPU.

Ewww! That's gross ;-)

Hey.  So is highmem ;)

But sys_sched_affinity() allows you to change the affinity of
other tasks (it takes a pid).  So that's torn that idea.
