Robert Richter a29aa8a7ff perf_counter, x86: implement the interrupt handler for AMD cpus
This patch implements the interrupt handler for AMD performance
counters. In difference to the Intel pmu, there is no single status
register and also there are no fixed counters. This makes the handler
very different and it is useful to make the handler vendor
specific. To check if a counter is overflowed the upper bit of the
counter is checked. Only counters where the active bit is set are
checked.

With this patch throttling is enabled for AMD performance counters.

This patch also reenables Linux performance counters on AMD cpus.

[ Impact: re-enable perfcounters on AMD CPUs ]
