Subject: [PATCH 2/6] perf, x86: Make perf amd ibs code depend on PERF_EVENTS and SUP_AMD

From: Andi Kleen <ak@...ux.intel.com>

Now that oprofile doesn't need the AMD IBS perf code anymore, we can
make that code dependent on PERF_EVENTS and AMD CPU support,
instead of unconditionally compiling it in.
