From 5ad29ea24e58777aa1daaa2255670ffb40aefd99 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Fri, 21 Sep 2012 18:17:24 +0100 Subject: ARM: hw_breakpoint: make boot quieter without CPUID feature registers Booting on a v6 core without the CPUID feature registers (e.g. 1136) leads to a noisy dmesg complaining about their absence. This patch changes the pr_warning into a pr_warn_once to keep the log quieter.
