From 9c93e596979021b159736a1273987c3e52d809e0 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 17 Jun 2009 16:34:45 +0900 Subject: [PATCH] sh: Generic HAVE_PERF_COUNTER support. This enables support for the generic software-based perf counters. Hardware counter support could be added in the future, but the lack of a performance counter IRQ makes this rather dubious.
