To avoid build problems and breaking dependencies between ACPI header files, <acpi/acpi.h> should not be included directly by code outside of the ACPI core subsystem. However, that is possible if <linux/acpi_io.h> is included, because that file contains a direct inclusion of <acpi/acpi.h>. For this reason, remove the direct <acpi/acpi.h> inclusion from <linux/acpi_io.h>, move that file from include/linux/ to include/acpi/ and make <linux/acpi.h> include it for CONFIG_ACPI set along with the other ACPI header files. Accordingly, Remove the inclusions of <linux/acpi_io.h> from everywhere. Of course, that causes the contents of the new <acpi/acpi_io.h> file to be available for CONFIG_ACPI set only, so intel_opregion.o that depends on it should also depend on CONFIG_ACPI (and it really should not be compiled for CONFIG_ACPI unset anyway).
