If the toolchain being used to build the kernel includes support for MSA then this patch will make use of that support & use MSA instructions directly. However toolchain support for MSA is very new & far from a point where it can be reasonably expected that everyone building the kernel uses a toolchain with support. Thus fallbacks using .word assembler directives are also provided for now as a temporary measure.
