Merge remote-tracking branch 'remotes/powerpc/topic/ppc-kvm' into kvm-ppc-next 



This merges in the ppc-kvm topic branch of the powerpc tree to get
two patches which are prerequisites for the following patch series,
plus another patch which touches both powerpc and KVM code.

Description:

		Perform SMBIOS calls on supported Dell machines.

		through the Dell ACPI-WMI interface.



		IOCTL's and buffer formats are defined in:

		<uapi/linux/wmi.h>



		1) To perform an SMBIOS call from userspace, you'll need to

		first determine the minimum size of the calling interface

		buffer for your machine.

		Platforms that contain larger buffers can return larger

		objects from the system firmware.

		Commonly this size is either 4k or 32k.



		To determine the size of the buffer read() a u64 dword from

		the WMI character device /dev/wmi/dell-smbios.



		2) After you've determined the minimum size of the calling

		interface buffer, you can allocate a structure that represents

		the structure documented above.



		3) In the 'length' object store the size of the buffer you

		determined above and allocated.



		4) In this buffer object, prepare as necessary for the SMBIOS

		call you're interested in.  Typically SMBIOS buffers have

		"class", "select", and "input" defined to values that coincide

		with the data you are interested in.

		Documenting class/select/input values is outside of the scope

		of this documentation. Check with the libsmbios project for

		further documentation on these values.



		6) Run the call by using ioctl() as described in the header.



		7) The output will be returned in the buffer object.



		8) Be sure to free up your allocated object.

KernelVersion:	4.15

Contact:	"Mario Limonciello" <mario.limonciello@dell.com>

Description:

		A read-only description of Dell platform tokens

		available on the machine.



		Each token attribute is available as a pair of

		sysfs attributes readable by a process with

		CAP_SYS_ADMIN.



		For example the token ID "5" would be available

		as the following attributes:



		0005_location

		0005_value



		Tokens will vary from machine to machine, and

		only tokens available on that machine will be

		displayed.

Description:

		Modify the platform force power state, influencing

		Thunderbolt controllers to turn on or off when no

		devices are connected (write-only)

		There are two available states:

		    * 0 -> Force power disabled

		    * 1 -> Force power enabled
