From 8cd3c23df79411f6b24ddb7d2ed58d26e3b06815 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Sun, 15 Apr 2012 20:54:59 +0000 Subject: powerpc: Remove empty giveup_altivec function on book3e CPUs Use an empty inline instead of an empty function to implement giveup_altivec on book3e CPUs, similar to flush_altivec_to_thread.
