From: James Hogan Date: Thu, 23 Jun 2016 16:34:35 +0000 (+0100) Subject: MIPS: uasm: Add CFCMSA/CTCMSA instructions X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=59e3559f48dcad3051f60c32775e028cd999ae53;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git MIPS: uasm: Add CFCMSA/CTCMSA instructions Add CFCMSA/CTCMSA instructions for accessing MSA control registers to uasm so that KVM can use uasm for generating its entry point code at runtime.
