oprofile for 2.5.41

Please see

http://oprofile.sourceforge.net/oprofile-2.5.html

for the necessary user-space tools, and the latest patch.

Note the change to fs/locks.c is necessary, otherwise you will end up dropping almost all samples on the floor. A proper patch hasn't yet made its way Linuswards...

This seems to work for me now. In the absence of any necessary major changes, I intend to split it up into readable chunks and feed it to Linus fairly soon.
