From 86c0baf123e474b6eb404798926ecf62b426bf3a Mon Sep 17 00:00:00 2001 From: Prarit Bhargava Date: Wed, 2 May 2007 19:27:05 +0200 Subject: [PATCH] [PATCH] i386: Change sysenter_setup to __cpuinit & improve __INIT, __INITDATA Change sysenter_setup to __cpuinit. Change __INIT & __INITDATA to be cpu hotplug aware.
