Date: Wed, 18 Dec 2013 17:06:08 +0800 From: Lv Zheng <lv.zheng@...el.com> To: "Rafael J. Wysocki" <rafael.j.wysocki@...el.com>, Len Brown <len.brown@...el.com> Cc: Lv Zheng <lv.zheng@...el.com>, Lv Zheng <zetalog@...il.com>, <linux-kernel@...r.kernel.org>, linux-acpi@...r.kernel.org Subject: [RFC PATCH 03/15] ACPICA: Linux: Add configurability for OSL APIs. OSPMs like Linux trend to include all header files but leave empty inline stub variables for a feature that is not configured during build. This patch configures ACPICA internal OSL prototypes out when ACPI is disabled to facilitate Linux with such configurability. Note that this patch is generated in the assumption that all ACPICA OSL APIs should only be used by ACPICA itself. While the real world is there are some external ACPICA macros called ACPICA OSL APIs. This patch doesn't include protections around the OSL APIs that are used by such ACPICA external macros.
