[PATCH] Documentation: RCU: update the stall warning message "timer=-1" to match reality

2012-09-21 Thread Paul Walmsley
The CONFIG_RCU_FAST_NO_HZ stall warning messages can never emit "timer=-1". This is because the printf() format specifier to generate that number is '%lu'. So, update the documentation to use the unsigned long equivalent instead, "timer=4294967295". This is what actually shows up in traces.
