This version is missing a few of the fixes included in my version:
it doesn't properly flush global tlb entries, or update the page
tables of processes which have copied 4MB page table entries into
their page tables. Also, the revert_page function must be called
before the tlb flush and free the page after the tlb flush, or
else tlb prefetching on the P4 can cache stale pmd pointers. I'd
suggest using the -C0 version which already has those fixes.
