Rozycki" <macro@xxxxxxxxxxx> Date: Sun, 1 May 2022 23:14:16 +0100 Subject: MIPS: IP27: Remove incorrect `cpu_has_fpu' override From: Maciej W. Rozycki <macro@xxxxxxxxxxx> commit 424c3781dd1cb401857585331eaaa425a13f2429 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.
