From ec30f343d61391ab23705e50a525da1d55395780 Mon Sep 17 00:00:00 2001 From: Shaohua Li Date: Mon, 24 Jan 2011 08:00:01 +0000 Subject: [PATCH] fix a shutdown regression in intel_idle Fix a shutdown regression caused by 2a2d31c8dc6f ("intel_idle: open broadcast clock event"). The clockevent framework can automatically shutdown broadcast timers for hotremove CPUs. And we get a shutdown regression when we shutdown broadcast timer for hot remove CPU, so just delete some code. Also fix some section mismatch.
