Merge branch 'perfcounters-rename-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
* 'perfcounters-rename-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: perf: Tidy up after the big rename perf: Do the big rename: Performance Counters -> Performance Events perf_counter: Rename 'event' to event_id/hw_event perf_counter: Rename list_entry -> group_entry, counter_list -> group_list Manually resolved some fairly trivial conflicts with the tracing tree in include/trace/ftrace.h and kernel/trace/trace_syscalls.c.
