X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=610f7ba93b1e4cda7370f367a6042cbda61227bb;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

hexagon: Provide atomic_{or,xor,and}

Implement atomic logic ops -- atomic_{or,xor,and}.

These will replace the atomic_{set,clear}_mask functions that are
available on some archs.
