As there is only CONFIG_ACPI=n processing in the <linux/acpi.h>, it is not safe to include <acpi/acpi.h> directly for source out of Linux ACPI subsystems. This patch adds error messaging to warn developers of such wrong inclusions. In order not to be bisected and reverted as a wrong commit, warning messages are carefully split into a seperate patch other than the wrong inclusion cleanups.
