From: James Hogan Date: Fri, 15 Apr 2016 09:07:26 +0000 (+0100) Subject: MIPS: Fix MSA assembly warnings X-Git-Tag: v4.7-rc1~122^2~247 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=92e9953c5865b47281d74d43f08d7cecde11e58a;p=karo-tx-linux.git MIPS: Fix MSA assembly warnings Building an MSA capable kernel with a toolchain that supports MSA produces warnings such as this: arch/mips/kernel/r4k_fpu.S:229: Warning: the `msa' extension requires 64-bit FPRs This is due to ".set msa" without ".set fp=64" in the non doubleword MSA load/store macros, since MSA requires the 64-bit FPU registers (FR=1). Add the missing fp=64 in these macros to silence the warnings.
