    Subject[PATCH 5.18 820/879] MIPS: IP27: Remove incorrect `cpu_has_fpu override
    Date
    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.
