From dbcb4660246c240a159b4037067fdedb563a63cb Mon Sep 17 00:00:00 2001 From: Glauber de Oliveira Costa Date: Wed, 30 Jan 2008 13:31:31 +0100 Subject: x86: unify TASK_ALIGN definitions This patch moves the TASK_ALIGN constraints to common header. The base of it is the same for x86_64 and i386. The only difference is the presence of vSMP in x86_64. As it's not a worry in i386, we can safely use the same code for both.
