Remove unsupported forcing of `cpu_has_fpu' to 1, which makes the `nofpu' kernel parameter non-functional, and also causes a link error:
ld: arch/mips/kernel/traps.o: in function `trap_init': ./arch/mips/include/asm/msa.h:(.init.text+0x348): undefined reference to `handle_fpe' ld: ./arch/mips/include/asm/msa.h:(.init.text+0x354): undefined reference to `handle_fpe' ld: ./arch/mips/include/asm/msa.h:(.init.text+0x360): undefined reference to `handle_fpe'
where the CONFIG_MIPS_FP_SUPPORT configuration option has been chosen.
Sorry, but I have a question. From the code in arch/mips/kernel/genex.S:567, 'handle_fpe’‘s definition is controlled by CONFIG_MIPS_FP_SUPPORT. Then how can it still report such error when the CONFIG_MIPS_FP_SUPPORT configuration option has been chosen.
