Date: Wed, 19 Mar 2008 14:26:14 -0300 From: Glauber de Oliveira Costa <gcosta@...hat.com> To: linux-kernel@...r.kernel.org Cc: akpm@...ux-foundation.org, tglx@...utronix.de, mingo@...e.hu, ak@...e.de, Glauber Costa <gcosta@...hat.com> Subject: [PATCH 79/79] [PATCH] remove smpboot_32.c and smpboot_64.c From: Glauber Costa <gcosta@...hat.com> Remove the last leftovers from the files. Move the ones that are still used to the files they belong, the others that grep can't reach, simply throw away.
