[PATCH v1 0/2] s390/uv: Provide Host-key-hashes in sysfs

[Steffen Eiden <seiden@linux.ibm.com>]

List the installed host keys in the sysfs if the machine supports the
Query Ultravisor Keys UVC.

As of now, two types of host keys are available:
The used/primary host key, and the backup hostkey both hastes are
available in a sysfs file.
For forwards compatibility an `all` file is also available that displays
the whole payload (15*32 bytes) and therefore future key hashes.

Steffen Eiden (2):
  s390/uv: Refactor uv-sysfs creation
  s390/uv: Provide host-key hashes in sysfs
