Rather than relying on a notifier for associating the KVM with
the group, let's assume that the association has already been
made prior to device_open.  The first time a device is opened
associate the group KVM with the device.

This fixes a user-triggerable oops in GVT.

Every caller has a readily available vfio_device pointer, use that instead
of passing in a generic struct device. The struct vfio_device already
contains the group we need so this avoids complexity, extra refcountings,
and a confusing lifecycle model.

The vfio_ap module tries to register for the vfio_ap bus - but that's
the interface that it provides itself, so this does not make much sense,
thus let's simply drop this statement now.

This patch tries to fix as much as possible of the
checkpatch.pl --strict findings:
  CHECK: Logical continuations should be on the previous line
  CHECK: No space is necessary after a cast
  CHECK: Alignment should match open parenthesis
  CHECK: 'useable' may be misspelled - perhaps 'usable'?
  WARNING: Possible repeated word: 'is'
  CHECK: spaces preferred around that '*' (ctx:VxV)
  CHECK: Comparison to NULL could be written "!msg"
  CHECK: Prefer kzalloc(sizeof(*zc)...) over kzalloc(sizeof(struct...)...)
  CHECK: Unnecessary parentheses around resp_type-&gt;work
  CHECK: Avoid CamelCase: &lt;xcRB&gt;

There is no functional change comming with this patch, only
code cleanup, renaming, whitespaces, indenting, ... but no
semantic change in any way. Also the API (zcrypt and pkey
header file) is semantically unchanged.

This patch does a little cleanup on the CPRBX struct
in zcrypt.h and the redundant CPRB struct definition in
zcrypt_msgtype6.c. Especially some of the misleading
fields from the CPRBX struct have been removed.

There is no semantic change coming with this patch.
The field names changed in the XCRB struct are only related
to reserved fields which should never been used.

<title>s390/ap: uevent on apmask/aqpmask change</title>
<updated>2022-04-25T11:54:13Z</updated>
<author>
<name>Harald Freudenberger</name>
<email>freude@linux.ibm.com</email>
</author>

<link rel='alternate' type='text/html' href='https://git.zx2c4.com/linux-dev/commit/?id=d9b38e9d0fd3be59122af56a299f84c951453598'/>
<id>urn:sha1:d9b38e9d0fd3be59122af56a299f84c951453598</id>
<content type='text'>
This patch introduces user space notifications for changes
on the apmask or aqmask attributes. So it could be possible
to write a udev rule to load/unload the vfio_ap kernel module
based on changes of these masks.

On chance of the apmask or aqmask an AP change event will
be produced with an uevent environment variable showing
the new APMASK or AQMASK mask.

So a change on the apmask triggers an uvevent like this:

  KERNEL[490.160396] change   /devices/ap (ap)
  ACTION=change
  DEVPATH=/devices/ap
  SUBSYSTEM=ap
  APMASK=0xffffffdfffffffffffffffffffffffffffffffffffffffffffffffffffffffff
  SEQNUM=13367

and a change on the aqmask looks like this:

  KERNEL[283.217642] change   /devices/ap (ap)
  ACTION=change
  DEVPATH=/devices/ap
  SUBSYSTEM=ap
  AQMASK=0xfbffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff
  SEQNUM=13348

Only real changes to the masks are processed - the old and
new masks are compared and no action is done if the values
are equal (and thus no uevent). The emit of the uevent is
the very last action done when a mask change is processed.
However, there is no guarantee that all unbind/bind actions
caused by the apmask/aqmask changes are completed when the
apmask/aqmask change uevent is received in userspace.

<title>s390/zcrypt: add display of ASYM master key verification pattern</title>

<id>urn:sha1:28d3417a946762bed46815e59627bbd749347906</id>
<content type='text'>
This patch extends the sysfs attribute mkvps for CCA cards
to show the states and master key verification patterns for
the old, current and new ASYM master key registers.

With this patch now all relevant master key verification
patterns related to a CCA HSM are available with the mkvps
sysfs attribute. This is a requirement for some exploiters
like the kubernetes cex plugin or initrd code needing to
verify the master key verification patterns on HSMs before
use.

A sample output:
