Subject: MIPS: kernel: proc: Add MIPS R6 support to /proc/cpuinfo
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=515a6393dbac4f4492237c7b305bbf9c4c558a1c;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

MIPS: kernel: proc: Add MIPS R6 support to /proc/cpuinfo

Print 'mips64r6' and/or 'mips32r6' if the kernel is running on
a MIPS R6 core.
