Reinette Chatre f3be1e7b2c x86/intel_rdt: Support L3 cache performance event of Broadwell
Broadwell microarchitecture supports pseudo-locking. Add support for
the L3 cache related performance events of these systems so that
the success of pseudo-locking can be measured more accurately on these
platforms.
