Date: Wed, 18 Dec 2013 17:06:38 +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 08/15] ACPICA: OSL: Updates ACPI_EXTERNAL_RETURN_x usages for external 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 external APIs out and defines them into function stubs when CONFIG_ACPI is not enabled. Lv Zheng.
