Subject: MIPS: cps-vec: Use macros for various arithmetics and memory operations
From: Markos Chandras <markos.chandras@xxxxxxxxxx>
commit b677bc03d757c7d749527cccdd2afcf34ebeeb07 upstream.
Replace lw/sw and various arithmetic instructions with macros so the
code can work on 64-bit kernels as well.
