		What: /sys/devices/.../deferred_probe
		Date: August 2016
		Contact: Ben Hutchings <ben.hutchings@codethink.co.uk>
		Description:
		The /sys/devices/.../deferred_probe attribute is
		present for all devices. If a driver detects during
		probing a device that a related device is not yet
		ready, it may defer probing of the first device. The
		kernel will retry probing the first device after any
		other device is successfully probed. This attribute
		reads as 1 if probing of this device is currently
		deferred, or 0 otherwise.

		Contact: Eric Auger <eric.auger@redhat.com>
		Description: /sys/kernel/iommu_groups/reserved_regions list IOVA
		regions that are reserved. Not necessarily all
		reserved regions are listed. This is typically used to
		output direct-mapped, MSI, non mappable regions. Each
		region is described on a single line: the 1st field is
		the base IOVA, the second is the end IOVA and the third
		field describes the type of the region.

		NOTE: At the moment DMA_ATTR_NO_WARN is only implemented on PowerPC.

		DMA_ATTR_PRIVILEGED
		------------------------------

		Some advanced peripherals such as remote processors and GPUs perform
		accesses to DMA buffers in both privileged "supervisor" and unprivileged
		"user" modes. This attribute is used to indicate to the DMA-mapping
		subsystem that the buffer is fully accessible at the elevated privilege
		level (and ideally inaccessible or at least read-only at the
		lesser-privileged levels).
