[PATCH 5.18 821/879] MIPS: IP30: Remove incorrect `cpu_has_fpu override

From: Greg Kroah-Hartman
Date: Tue Jun 07 2022 - 21:31:11 EST


From: Maciej W. Rozycki <macro@xxxxxxxxxxx>

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.
