Kernel memory leak detector

A new kmemleak version is available. Thanks to all who reviewed the code
and provided feedback. Kmemleak can also be found on this git tree:

git://linux-arm.org/linux-2.6.git kmemleak

Main changes since the previous release:

- run-time configuration by writing to the /sys/kernel/debug/memleak
  file (see Documentation/kmemleak.txt)
- boot-time disabling by passing kmemleak=off
- no scanning of the array_cache structures in slab to avoid false
  negatives
- aesthetic change - s/memleak/kmemleak for all the functions as it is
  more consistent with the documentation
- various other changes following comments received

Thanks for your comments.
