Subject: Always use ".set mips3" rather than select between "mips2" or "mips3"
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c4559f67b73d6c34fde0faac5c6c890a2cf3527c;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

Always use ".set mips3" rather than select between "mips2" or "mips3"
for assembling ll/sc sequences to avoid problems with 64-bit
configurations.
