This patch supports the addition to the kernel of AUX area buffers that can be mmapped separately from the perf-events buffer. The AUX buffer can be configured to contain hardware-produced trace information. The first implementation will support Intel BTS and Intel PT. One auxtrace buffer is mmapped per perf-events buffer. If the requested auxtrace buffer size is zero, which it will be until further support is added, then no auxtrace mmapping is attempted.
