Bug description:

== SRU Justification ==
IBM is requesting this patch in all releases order to fix the sleep-in-atomic
bugs in AES-CBC and AES-XTS VMX implementations.

This patch is a clean cherry pick and has already been applied to
Cosmic. It is also needed in Xenial, but there was a minor context
diff, so the Xenial SRU will be sent separatly.

== Fix ==
0522236d4f9c ("crypto: vmx - Fix sleep-in-atomic bugs")

== Regression Potential ==
Low. This patch has also been cc'd to upstream stable, so it has had
additional upstream review.

== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
