Yes grumble. Why does it take so long...
Would it be possible to merge this for 2.6.23 (maybe late?). This has been
around for 6 months now. It removes the troubling lookups in
virt_to_page and page_address in sparsemem that have spooked many of us.
virt_to_page efficiency is a performance issue for kfree and
kmem_cache_free in the slab allocators. I inserted probles and saw
that the patchset cuts down the cycles spend in virt_to_page by 50%.
