commit f44b3e74c33fe04defeff24ebcae98c3bcc5b285 upstream.
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 disabled.
