Commit 977e043d ("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. Signed-off-by:
