2014-07-23ACPICA: Linux: Add support to exclude <asm/acenv.h> inclusion.Lv Zheng
The forthcoming patch will make <acpi/acpi.h> to be visible to all kernel source code. Thus for the architectures that do not support ACPI and haven't implemented <asm/acenv.h>, we need to make it excluded. Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
2014-05-27ACPICA: Clean up redudant definitions already defined elsewhereLv Zheng
Since mis-order issues have been solved, we can cleanup redundant definitions that already have defaults in <acpi/platform/acenv.h>. This patch removes redudant environments for __KERNEL__ surrounded code.

2014-05-27ACPICA: Linux headers: Add <asm/acenv.h> to remove mis-ordered inclusion of ↵Lv Zheng
<asm/acpi.h> There is a mis-order inclusion for <asm/acpi.h>. As we will enforce including <linux/acpi.h> for all Linux ACPI users, we can find the inclusion order is as follows: <linux/acpi.h> <acpi/acpi.h> <acpi/platform/acenv.h> (acenv.h before including aclinux.h) <acpi/platform/aclinux.h> ........................................................................... (aclinux.h before including asm/acpi.h) <asm/acpi.h> @Redundant@ (ACPICA specific stuff) ........................................................................... ........................................................................... (Linux ACPI specific stuff) ? - - - - - - - - - - - - + (aclinux.h after including asm/acpi.h) @Invisible@ | (acenv.h after including aclinux.h) @Invisible@ | other ACPICA headers @Invisible@ | ............................................................|.............. <acpi/acpi_bus.h> | <acpi/acpi_drivers.h> | <asm/acpi.h> (Excluded) | (Linux ACPI specific stuff) ! <- - - - - - - - - - - - - + NOTE that, in ACPICA, <acpi/platform/acenv.h> is more like Kconfig generated <generated/autoconf.h> for Linux, it is meant to be included before including any ACPICA code. In the above figure, there is a question mark for "Linux ACPI specific stuff" in <asm/acpi.h> which should be included after including all other ACPICA header files. Thus they really need to be moved to the position marked with exclaimation mark or the definitions in the blocks marked with "@Invisible@" will be invisible to such architecture specific "Linux ACPI specific stuff" header blocks. This leaves 2 issues: 1. All environmental definitions in these blocks should have a copy in the area marked with "@Redundant@" if they are required by the "Linux ACPI specific stuff". 2. We cannot use any ACPICA defined types in <asm/acpi.h>. This patch splits architecture specific ACPICA stuff from <asm/acpi.h> to fix this issue.
