[PATCH][RFC] oprofile for 2.5.40

[John Levon]

Here is a new version of oprofile against 2.5.40.
 
As before, the full patch is available here :
 
http://oprofile.sf.net/oprofile-2.5/oprofile-2.5-all.diff [93k]
 
with usage notes :
 
http://oprofile.sf.net/oprofile-2.5.html
 
and more readable broken-out patches (but not applyable) :
 
http://oprofile.sf.net/oprofile-2.5/

Changes from the last version

o remove the ctx switch hook
o make event buffer be untyped ulong[] and use escapes for changing
  cpu/context/cookie. This reduces the amount of data considerably.
o use EXPORT_SYMBOL_GPL
o more fixes and cleanups

Does anybody want to try this out ?
