Subject: MIPS: Treat CP1 control registers as unsigned ints.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c46a2f01fb2bea6ae7e4e3f3f2aad65d8eda837d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

MIPS: Treat CP1 control registers as unsigned ints.

These are bitfields and treating them as signed values doesn't make
any sense.
