From c32017a43d552b78717160bf6aab2af8a7ff84c4 Mon Sep 17 00:00:00 2001 From: Dave Jones Date: Tue, 20 Dec 2005 14:46:07 -0800 Subject: [PATCH] [X86] Rename MTRR mutex to something more sensible. I spotted 'main_lock' whilst grovelling through a vmlinux with objdump. Even if it is static, it's a horrible name.
