[PATCH 00/15] s390x: Protected Virtualization support

[Janosch Frank]

Most of the QEMU changes for PV are related to the new IPL type with
subcodes 8 - 10 and the execution of the necessary Ultravisor calls to
IPL secure guests. Note that we can only boot into secure mode from
normal mode, i.e. stfle 161 is not active in secure mode.

The other changes related to data gathering for emulation and
disabling addressing checks in secure mode, as well as CPU resets.

While working on this I sprinkled in some cleanups, as we sometimes
significantly increase line count of some functions and they got
unreadable.
