From 278d91c4609d55202c1e63d5fc5f01466cc7bbab Mon Sep 17 00:00:00 2001 From: Akira Takeuchi Date: Wed, 27 Oct 2010 17:28:52 +0100 Subject: MN10300: Make the FPU operate in non-lazy mode under SMP Make the FPU operate in non-lazy mode under SMP so that when the process that is currently using the FPU migrates to a different CPU, we don't have to ping its previous CPU to flush the FPU context.
