From 75eedfed3e2d05563f44d2f69efb991fad95d7f1 Mon Sep 17 00:00:00 2001 From: Olof Johansson Date: Thu, 4 Aug 2005 12:53:29 -0700 Subject: [PATCH] ppc64: Fix UP kernel build CONFIG_KEXEC breaks UP builds because of a misspelled smp_release_cpus(). Also, the function isn't defined unless built with CONFIG_SMP but it is needed if we are to go from a UP to SMP kernel. Enable it and document it. Thanks to Steven Winiecki for reporting this and to Milton for remembering how it's supposed to work and why.
