From: Steven Rostedt <[email protected]> 3.12-stable review patch. If anyone has any objections, please let me know.
=============== commit 32abc2ede536aae52978d6c0a8944eb1df14f460 upstream. When a long value is read on 32 bit machines for 64 bit output, the parsing needs to change "%lu" into "%llu", as the value is read natively. Unfortunately, if "%llu" is already there, the code will add another "l" to it and fail to parse it properly.
