-Commit 977e043d5ea1 ("MIPS: kernel: cps-vec: Replace mips32r2 ISA level
-with mips64r2") leads to .set mips64r2 directives being present in 32
-bit (ie. CONFIG_32BIT=y) kernels. This is incorrect & leads to MIPS64
-instructions being emitted by the assembler when expanding
-pseudo-instructions. For example the "move" instruction can legitimately
-be expanded to a "daddu". This causes problems when the kernel is run on
-a MIPS32 CPU, as CONFIG_32BIT kernels of course often are...
-
-Fix this by dropping the .set <ISA> directives entirely now that Kconfig
-should be ensuring that kernels including this code are built with a
-suitable -march= compiler flag.
