perf_counter: Set the CONFIG_PERF_COUNTERS default to y if CONFIG_PROFILING=y
If user has already enabled profiling support in the kernel (for oprofile, old-style profiling of ftrace) then offer up perfcounters with a y default in interactive kconfig sessions. Still keep it off by default otherwise. Cc: Peter Zijlstra <peterz@infradead.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
