From 5042afe7fe32390e79910ecd0a1f0563d4bca38c Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Fri, 3 Jul 2009 08:29:30 -0500 Subject: [PATCH] generic: Use raw local irq variant for generic cmpxchg The interrupt disabled region is extremly tiny and therefor not latency relevant. Avoid cluttering the traces with those pointless entries.
