per Intel policy to include file commit date using git cmd
below. The policy does not apply to non-Intel (C) notices.
git log --follow -C90% --format=%ad --date default <file> | tail -1
and then pull just the 4 digit year from the result.
Intel copyrights were not added to files where Intel either had
no contribution ot the contribution lacked substance (ie license
header updates, formatting changes, etc). Contribution date used
"--follow -C95%" to get the most accurate date.
Note that several files in this patch didn't end the license/(c)
block with a blank comment line so these were added as the vast
majority of files do have this last blank line. Simply there for
consistency.

If the kernel is booted with the IOMMU enabled and Shared Memory mode
enabled (which are the expected boot parameters for production servers),
then the kernel idxd driver will automatically register a dedicated work
queue with the PASID for the process that opens it. This means that the
descriptors written into the portal for that work queue should be
*virtual* addresses.
If the IOMMU is enabled but Shared Memory mode is disabled, then the
kernel has registered the device with the IOMMU and assigned it I/O
virtual addresses. We have no way to get those addresses from user
space, so we cannot use the kernel driver in this mode. Add a check to
catch that.
If the IOMMU is disabled, then physical addresses are used everywherre.
