Bug Description
---Problem Description---
Some CAPI Flash cards need notification of device shutdown
in order to flush pending I/Os.
A PCI notification hook for shutdown has been added where
the driver notifies the card and returns. When the device
is removed in the PCI remove path, this code will wait for
shutdown processing to complete. It could take a minimum of
1 second for shutdown processing to complete. To avoid an
indefinite wait, code has been added to read the status
incrementally from 100ms up to 1.5 seconds.

This is a defect placeholder for submitting a patch to Canonical, that is in the process of getting submitted upstream for the 4.8 kernel.
We would like to have this patch included in the pointrelease, 16.04.1.
Please lookout for the patch that will be attached to this bug soon and probably closer to the deadline for 16.04.1.
I will submit the patch as soon as I get the review comments addressed and well tested.

I have two requests.
1. Can you please backport below commit from upstream ?
9526f36026f778e 82b517524944385 4c03b2e660 cxlflash: Fix regression issue with re-ordering patch
This commit fixes a regression issue with the patch that I see in Xenial SRU - Commit 6ded8b3cbd9a ("cxlflash: Unmap problem state area before detaching
master context"). Please backport this patch to Xenial SRU.
2. I'm submitting the patch series that was sent upstream as NOUP/SAUCE request. Here is the link to upstream submission.

I'm also attaching these three patches as attachment cut against xenial/master-next plus the patch 9526f36026f778e 82b517524944385 4c03b2e660 cxlflash: Fix regression issue with re-ordering patch.
So please apply it on top of the backported patch.
