hsci is used to control and show HSCI (HiperSockets Converged Interfaces)
settings. A HiperSockets interface and an external network interface are
converged to an HSCI interface.

Protected VMs (PVM) are KVM VMs, where KVM can't access the VM's state
like guest memory and guest registers anymore. Instead the PVMs are
mostly managed by a new entity called Ultravisor (UV), which provides
an API, so KVM and the PV can request management actions.
PVMs are encrypted at rest and protected from hypervisor access while
running. They switch from a normal operation into protected mode, so
we can still use the standard boot process to load an encrypted image
and then move it into protected mode.
This commit adds the tool 'genprotimg'. It takes a kernel, key files,
optionally an initrd, optionally a file with the kernel command line,
and it generates a single, loadable image file. The image consists of
a concatenation of a plain text boot loader, the encrypted components
for kernel, initrd, and cmdline, and the integrity-protected PV
header, containing metadata necessary for running the guest in PV
mode.
It's possible to use this image file as a kernel for zipl or for a
direct kernel boot using QEMU.

zpcictl is used to manage PCI devices on z Systems. In this first
version it is mainly used to handle erroneous PCI devices by changing
their state and make those changes known to the SE. Log data, such as
S.M.A.R.T. data for NVMe devices, is sent alongside those state changes.
The state change is issued by sending data via the PCI 'report_error'
sysfs attribute. It's a binary attribute which will cause the host to
send an Adapter Notification Event.

This patch prevents code duplication in vmcp related programs.
Some applications such as vmur, vmcp, and lsqeth
use z/VM CP commands to query information. Each program
uses its own defines and code.
Supply a library and common header file to use common code.

A set of scripts and a short documentation describing how to build
a network boot image simulating a PXELINUX-style boot process.
Starting with QEMU 2.10 it is possible to boot a KVM guest over a
network interface using DHCP/BOOTP. The boot process is triggered by
the network boot firmware that is part of QEMU and follows the usual
network boot pattern: a DHCP request is issued by the client and
answered by a DHCP/BOOTP server. The DHCP reply will contain a
TFPT server identification and a bootfile name. The client will
retrieve the bootfile from the TFTP server, load it into memory
and IPL it.
A very common way of setting up a boot server has been defined
by PXELINUX, an open source implementation of PXE. With PXELINUX
the bootfile is a small network boot loader that will retrieve
a potentially client-specific configuration file containing
further instructions for the final boot process (kernel, ramdisk,...).
The set of sample scripts contained in the netboot directory provide
directions for a Linux distributor or a boot server administrator
on how to build a network boot image usable for a simplified
PXELINUX-style network boot setup for s390.
Note that the sample scripts are implementing only a subset of PXELINUX
functionality, specifically the config file parsing. In order to
get full functionality, a more specialized boot loader program
like petitboot or pxe-kexec must be used in the ramdisk.
Further, a sample Dockerfile is provided along with instructions on how
to build the network boot image in a Docker container.
