From 976513dbfc1547c7b1822566923058655f0c32fd Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Fri, 7 Jan 2011 01:43:44 +0100 Subject: PM / ACPI: Move NVS saving and restoring code to drivers/acpi The saving of the ACPI NVS area during hibernation and suspend and restoring it during the subsequent resume is entirely specific to ACPI, so move it to drivers/acpi and drop the CONFIG_SUSPEND_NVS configuration option which is redundant.
