Subject: [RFC PATCH 10/15] ACPICA: Linux: Add architecture specific ACPICA headers in Linux.
Date: Wed, 18 Dec 2013 17:06:51 +0800 [thread overview]
Message-ID: <c682336441ac2e8d4ddd3c0cd56ca60d48e6b06e.1387336613.git.lv.zheng@intel.com> (raw)
In-Reply-To: <cover.1387336613.git.lv.zheng@intel.com>
Our target is allowing inclusion of <acpi/acpi.h> for CONFIG_ACPI=n build.
This patch tries to achieve this by splitting architecture specific ACPICA
implementation from <asm/acpi.h> into <asm/acenv.h> to improve
maintainability. Then <asm/acpi.h> could be treated as the architecture
specific part of <linux/acpi.h>, <acpi/acpi_bus.h>,
<acpi/acpi_drivers.h>.
We need to delete <asm/acpi.h> from aclinux.h to achieve our CONFIG_ACPI=n
build target, but in order not to affect Linux build process, it requires
further cleanup on <linux/acpi.h>, <acpi/acpi_bus.h>,
<acpi/acpi_drivers.h> inclusions be done before doing this.
