From: Ingo Molnar Date: Wed, 28 Jan 2009 18:04:37 +0000 (+0100) Subject: x86, bigsmp: consolidate code X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=b3daa3a1a56cf09fb91773f3658692fd02d08bb1;p=deliverable%2Flinux.git x86, bigsmp: consolidate code Move all code to arch/x86/kernel/bigsmp_32.c. With this it ceases to rely on any build-time subarch features.
