From 8b3ed3c002666540d9782a5219fa75c8a3fba98f Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Fri, 21 Jun 2013 18:17:22 +0100 Subject: [PATCH] alpha: locks: remove unused arch_*_relax operations The arch_{spin,read,write}_relax macros are not used anywhere in the kernel and are typically just aliases for cpu_relax(). This patch removes the unused definitions for Alpha.
