So if the above code actually did anything, this change would have broken it for xor-sse.c. However, based on arch/x86/um/Kconfig, CONFIG_X86_32 is always the opposite of CONFIG_64BIT, so the above code actually has no effect. Does that sound right? - Eric _______________________________________________ linux-riscv mailing list linux-riscv@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-riscv
