			What: /sys/firmware/acpi/pm_profile
			Date: 03-Nov-2011
			KernelVersion: v3.2
			Contact: linux-acpi@vger.kernel.org
			Description: The ACPI pm_profile sysfs interface exports the platform
			power management (and performance) requirement expectations
			as provided by BIOS. The integer value is directly passed as
			retrieved from the FADT ACPI table.
			Values: For possible values see ACPI specification:
			5.2.9 Fixed ACPI Description Table (FADT)
			Field: Preferred_PM_Profile

			Currently these values are defined by spec:
			0 Unspecified
			1 Desktop
			2 Mobile
			3 Workstation
			4 Enterprise Server
			5 SOHO Server
			6 Appliance PC
			7 Performance Server
			>7 Reserved
