sparc64: Add perf_event abstractions for orthogonal PMUs. Starting with SPARC-T4 we have a seperate PCR control register for each performance counter, and there are absolutely no restrictions on what events can run on which counters. Add flags that we can use to elide the conflict and dependency logic used to handle older chips. Signed-off-by: David S. Miller <davem@davemloft.net>
