From: Paul Mackerras Date: Mon, 3 Nov 2014 04:46:43 +0000 (+1100) Subject: powerpc: Fix compilation of emulate_step() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7048c846949ac1feb09d1b624ea0e8c351d92a7b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git powerpc: Fix compilation of emulate_step() Commit be96f63375a1 ("powerpc: Split out instruction analysis part of emulate_step()") added some calls to do_fp_load() and do_fp_store(), which fail to compile on configs with CONFIG_PPC_FPU=n and CONFIG_PPC_EMULATE_SSTEP=y. This fixes the compile by adding #ifdef CONFIG_PPC_FPU around the code that calls these functions.
