Merge branch 'acpi-headers'
* acpi-headers:
ACPI: Add support to force header inclusion rules for <acpi/acpi.h>.
ACPI / SFI: Fix wrong <acpi/acpi.h> inclusion in SFI/ACPI wrapper - table definitions.
ACPICA: Linux: Allow ACPICA inclusion for CONFIG_ACPI=n builds.
ACPICA: Linux: Add support to exclude <asm/acenv.h> inclusion.
ACPICA: Linux: Add stub implementation of ACPICA 64-bit mathematics.
ACPICA: Linux: Add stub support for Linux specific variables and functions.
