From 5f20be4478032eeba66abddc79eae3abea45c5c8 Mon Sep 17 00:00:00 2001 From: Kevin Hao Date: Sun, 14 Jul 2013 17:02:06 +0800 Subject: powerpc: Remove the empty giveup_fpu() function on 32bit kernel Instead of implementing an empty giveup_fpu() function for each 32bit processor type, replace them with an unique empty inline function.
