| Subject: MIPS: IP27: Remove incorrect `cpu_has_fpu' override |
| |
| From: Maciej W. Rozycki <macro@orcam.me.uk> |
| |
| 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. |
