[PATCH][RFC] oprofile for 2.5.39

[John Levon <movement@marcelothewonderpenguin.com>]

Here is a new version of oprofile against 2.5.39. Thanks Andi,
Christoph, and Alan for your comments. I think I should have fixed
the things you mentioned.

As before, the full patch is available here :

with usage notes :

and more readable broken-out patches (but not applyable) :

Changes from last time :

o More comments on the fiddly bits
o Fix for NMI on shutdown
o Added stats
o avoid some mis-attributed samples
o Re-worked FS stuff
o Moved x86 stuff into arch/
o Fixed UP build
o various fixes and cleanups
