[PATCH] ACPI / PM: Fix build problems for !CONFIG_ACPI related to NVS rework

From: Rafael J. Wysocki
Date: Wed Jan 12 2011 - 16:04:38 EST


From: Rafael J. Wysocki <rjw@xxxxxxx>

The recent rework of the NVS saving/restoring code introduced two
build issues for !CONFIG_ACPI, a warning in drivers/acpi/internal.h
and an error in arch/x86/kernel/e820.c.

Fix them by providing suitable static inline definitions of the
relevant functions.
