Right; I assumed I had to have that SELECT. My apologies -- I still cannot reproduce the warning. I'll resubmit the patch incorporating the suggestion, though, since the result ends up being the same -- you must have ACPI and EXPERT selected in order to enable ACPI_REDUCED_HARDWARE_ONLY.
You should never 'select' CONFIG_EXPERT from architecture code, that is supposed to be a user-settable option. If you also select CONFIG_EXPERT or have that enabled in the configuration, you will not get a warning.
