But anyway, if Dmitry also thinks > this patch should be split, I will send a new version. :) The reason for ia64 not emitting this message is because we "trust" ia64 firmware and it is quite normal for it not to have i8042 implementation, whereas there are a lot of legacy devices on x86 and not having PS/2 keyboard is still not very common. I moved the pr_info() back into x86/loongarch branch and applied. Thanks.

LoongArch uses ACPI and nearly the same as X86/IA64 for 8042. So modify i8042-acpipnpio.h slightly and enable it for LoongArch in i8042.h. Then i8042 driver can work well under the ACPI firmware with PNP typed key- board and mouse configured in DSDT.
