Single threaded write-fault based allocation performance is improved ~5% on G5 with SMP kernel, and ~7% on P4 Xeon with SMP kernel (this measurement includes the full fault path, page copy, unmapping, and page freeing, so actual kernel allocator improvement should be larger). Thanks to feedback from Christoph, Andi, and Bob Picco. This patchset is cut down to include just straight optimisations and no behavioural changes. Nick -- SUSE Labs, Novell Inc.
