<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif";color:black">mips64 Android bionic has dropped the mips32-specific cacheflush() routine.<br>
Use the compiler's __clear_cache builtin on mips and mips64, as already done for arm and aarch64.<br>
Delete dead code for calling Android's mutated-arg version of mips32 cacheflush().<br>
