commit 17278a91e04f858155d54bee5528ba4fbcec6f87 upstream.
MIPS CPS has a build warning on kernels configured for MIPS32R1 or MIPS64R1, due to the use of .set mt without a prior .set mips{32,64}r2:
arch/mips/kernel/cps-vec.S Assembler messages: arch/mips/kernel/cps-vec.S:238: Warning: the `mt' extension requires MIPS32 revision 2 or greater
Add .set MIPS_ISA_LEVEL_RAW before .set mt to silence the warning.
