Sync up with some small bits from latest 2.4pre, a few pending
items, and the initial merge of the CPU frequency scaling code.
This should also fix the problems that various people saw with
capabilities.

As usual,..

Patch against 2.5.20 vanilla is available from:
ftp://ftp.kernel.org/pub/linux/kernel/people/davej/patches/2.5/

Merged patch archive: http://www.codemonkey.org.uk/patches/merged/

Check http://www.codemonkey.org.uk/Linux-2.5.html before reporting
known bugs that are also in mainline.
