Cyrill Gorcunov 1ff3d7d792 x86, perf: P4 PMU - fix counters management logic ... Jaswinder reported this #GP: | | Message from syslogd@ht at May 14 09:39:32 ... | kernel:[ 314.908612] EIP: [<c100ccca>] | x86_perf_event_set_period+0x19d/0x1b2 SS:ESP 0068:edac3d70 | Ming has narrowed it down to a comparision issue between arguments with different sizes and signs. As result event index reached a wrong value which in turn led to a GP fault. At the same time it was found that p4_next_cntr has broken logic and should return the counter index only if it was not yet borrowed for another event.
