	Commit b24413180f5600 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license") was meant to do a tree-wide cleanup for files without any license information by adding a SPDX GPL-2.0 line to them. Unfortunately this was applied even to several Xen-related headers which have been originally under the MIT license, but obviously have been copied to the Linux tree from the Xen project without keeping the license boiler plate as required. Correct that by changing the license of those files back to "MIT". Some files still contain the MIT license text. Replace that by the related SPDX line.

2017-02-14	xen/privcmd: Add IOCTL_PRIVCMD_DM_OP	Paul Durrant
	Recently a new dm_op[1] hypercall was added to Xen to provide a mechanism for restricting device emulators (such as QEMU) to a limited set of hypervisor operations, and being able to audit those operations in the kernel of the domain in which they run. This patch adds IOCTL_PRIVCMD_DM_OP as gateway for __HYPERVISOR_dm_op. NOTE: There is no requirement for user-space code to bounce data through locked memory buffers (as with IOCTL_PRIVCMD_HYPERCALL) since privcmd has enough information to lock the original buffers directly.
