From 698613b63817f2f6ca79831cd1c37aae67025323 Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 3 Apr 2013 16:33:26 +0100 Subject: [PATCH] ARM: iWMMXt: always enable iWMMXt support with PJ4 CPUs Jason Cooper reports these build errors: arch/arm/kernel/built-in.o: In function `iwmmxt_do': /.../arch/arm/kernel/pj4-cp0.c:36: undefined reference to `iwmmxt_task_release' /.../arch/arm/kernel/pj4-cp0.c:40: undefined reference to `iwmmxt_task_switch' make: *** [vmlinux] Error 1 This is caused because the PJ4 code explicitly references the iWMMXt code, but doesn't require it to be built. Fix this by ensuring that iWMMXt is always enabled with PJ4.
