From 7cc1712b8a778c8077048969848857895d242009 Mon Sep 17 00:00:00 2001 From: Coywolf Qi Hunt Date: Thu, 5 May 2005 14:53:01 -0700 Subject: [PATCH] [SPARC]: Remove legacy stuff from cpu_idle(). Currently sparc and sparc64's UP cpu_idle() checks current pid. This is old time legacy. Now it's paranoia. Signed-off-by: Coywolf Qi Hunt Acked-by: William Irwin Signed-off-by: David S.
