From 4eb96fcfe07b7f2a05577e57533840f8e26bea53 Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Fri, 9 Jan 2009 17:24:34 +1100 Subject: [PATCH] perf_counter: Add dummy perf_counter_print_debug function Impact: minimize requirements on architectures Currently, an architecture just enabling CONFIG_PERF_COUNTERS but not providing any extra functions will fail to build with perf_counter_print_debug being undefined, since we don't provide an empty dummy definition like we do with the hw_perf_* functions. This provides an empty dummy perf_counter_print_debug() to make it easier for architectures to turn on CONFIG_PERF_COUNTERS.
