Cover letter [PATCH 0/7] Start using sysctl paths in the core kernel code
The patches from Eric, that add support for so called ctl_paths has recently being accepted, so I hope we can start using this very useful feature.
To begin with, I switched the core kernel code to use the paths. The rest code to be patched (after this set) will be:
* arch-specifi,
* some filesystems,
* networking.
After this set the total vmlinux size decrease is ~500 bytes:
add/remove: 5/6 grow/shrink: 5/1 up/down: 121/-616 (-495)

The set is prepared to fit the 2.6.24-rc3-mm2 kernel with Eric's patches concerning sysctls.
