The Oprofile patches (by Will Deacon) are in Russell's devel tree and
intended for upstream merge:

http://ftp.arm.linux.org.uk/git/gitweb.cgi?p=linux-2.6-arm.git;a=shortlog;h=refs/heads/devel

My stable repository has some old Oprofile implementation (it requires
additional patches for user space - I can dig them out if you really
need them but I would recommend Will's version).
