i cant find anything in Documentation/ covering perf counters. did i miss some file ?

there is also some ptrace type piece missing for the Blackfin arch, but that looks like something that i should just implement as everyone else is doing it. -mike -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
