There is already a long thread about that, along with patches:

If you need a patch for 3.6, here is what I did before I found the above

Subject: [PATCH] arm: arch timer: export read_current_timer()
Exporting read_current_timmer is needed e.g. for users of get_cycles()
like udlfb which otherwise can't be build as a module.
This seems to have been forgotten in
commit 923df96b9f31b7d08d8438ff9677326d9537accf.
