[PATCH v1 3/5] powerpc/405: Fix build failure with GCC 12 (unrecognized opcode: `wrteei')

From: Christophe Leroy
Date: Mon Jul 11 2022 - 10:20:29 EST


Building ppc40x_defconfig leads to following error

CC arch/powerpc/kernel/process.o
{standard input}: Assembler messages:
{standard input}:626: Error: unrecognized opcode: `wrteei'

Add -mcpu=405 by default.
