Subject: RE: [PATCH v2] ACPI: Cleanup <acpi/acpi.h>, <acpi/acpi_bus.h> and
 <acpi/acpi_drivers.h> inclusions.

Hi, All

I think:

For <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>, what has been done in this patch is correct as according to my investigation, they are only used for CONFIG_ACPI=y code.

For <acpi/acpi.h> inclusion cleanups, we need to make stubs for ACPICA first or the following files that originally only reference ACPICA structures (for examples, table headers) may face build issues.
As files include them may not be surrounded by "#ifdef CONFIG_ACPI".

The affected files are:
include/linux/tboot.h
include/linux/iscsi_ibft.h
include/linux/acpi_io.h
drivers/iommu/intel_irq_remapping.c
drivers/char/tpm/tpm_acpi.c
arch/x86/kernel/apic/apic_flat_64.c
arch/x86/pci/mmconfig_32.c
include/linux/ide.h

Should we get this issue discussed prior than doing an <acpi/acpi.h> cleanups?

Thanks and best regards
-Lv
