Subject: [PATCH] [FEAT VS1822] ap_tools/ap-check: use new mdevctl install location
From: Matthew Rosato <mjrosato@linux.ibm.com>

Summary:     ap_tools: add ap-check and the ap device type to zdev   
Description: This feature adds multiple components in support of persistent
             configuration of vfio-ap mediated devices.

The ap-check utility is added as a callout function for the
             mdevctl utility.  This allows for meaningful error messages to be
             presented to end-users when vfio-ap configuration errors are
             detected while using mdevctl to create/modify vfio-ap mediated
             devices.

Additionally, the 'ap' device type is added to zdev, providing a
             command-line interface for managing the apmask and aqmask, which
             determine what AP resources are available for vfio-ap usage.
             'chzdev' is updated to allow for modifying the active masks as
             well as to specify persistent mask values via a udev rule.
             'lszdev' is updated to allow for querying of the active and
             persistent mask values.

Upstream-Description:

ap_tools/ap-check: use new mdevctl install location

mdevctl has been updated to use /usr/lib/mdevctl/scripts.d/callouts/
             instead of /etc/mdevctl.d/scripts.d/callouts/.  The /etc location
             is considered deprecated, meaning mdevctl will also look at that
             location for now but might eventually stop looking in /etc for
             callout scripts.
             Based on that, update the installation location for the ap-check
             callout.  However, because older versions of mdevctl will still
             only look in /etc, let's also put a wrapper script in /etc for now
             to provide backward compatibility, and plan to remove it at a
             later time.
