From 187818cd6a5ab6343eac47e52da2f3e40c544b98 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sun, 28 Oct 2012 13:04:47 -0700 Subject: sparc64: Improvde documentation and readability of atomic backoff code. Document what's going on in asm/backoff.h with a large and descriptive comment. Refer to it above the cpu_relax() definition in asm/processor_64.h Rename the pause patching section to have "3insn" in it's name like the other patching sections do. Based upon feedback from Sam Ravnborg. Signed-off-by: David S.
