Add mem-loads/mem-stores events to sysfs. The event is formed based on raw event encoding. Primary PMU event used here is PM_MRK_INST_CMPL along with MMCRA[SM] modes and Thresholding bit Signed-off-by: Madhavan Srinivasan <maddy@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
