From 687b16fb617bd446439425a368ad7c7bbd202c73 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Fri, 13 Nov 2009 13:16:15 +0100 Subject: hw-breakpoints: Provide an off-case for counter_arch_bp() If an arch doesn't support the hw breakpoints, counter_arch_bp() has no off case to cover the missing breakpoint info structure from the perf event. The result is a build error in non-x86 configs.
