hello qemu-*@nongnu.org, this is my first contribution. apologies if
something is incorrect.

this patch fixes vmware_vga.c so that it actually returns the cursory
register when asked for, instead of cursorx.

We call g_free() after cache_fini() in migration_end(), but we don't
call it after cache_fini() in xbzrle_cache_resize(), leaking the
memory.

cache_init() and cache_fini() are a pair.  Since cache_init()
allocates the cache, let cache_fini() free it.  This plugs the leak.

Several patches for s390:

- bugfixes: A fix for a long-standing bug in the css code as well as
  a fixup for the recent I/O adapter support.
- Exploitation of the userspace cmma enablement/reset interface, if
  it is present.
- Some debuggability improvements by logging unmanageable conditions.
- virtio-ccw finally gets migration support for its structures.
- Some cleanup as to how floating interrupts are injected.

The kernel only drops to userspace if an endless program interrupt loop

just like it is already done for the external interruption loop detection.

Interception code 0x14 only drops to userspace when an unmanageable
external interruption interception occured (e.g. if the External New
PSW does not disable external interruptions). Instead of bailing out
via the default handler, it is better to inform the user with a
proper error message that also includes the bad PSW, and to stop
the affected CPU with a panic event instead.

Exploit the new api for userspace-controlled cmma. If supported, enable
cmma during kvm initialization and register a reset handler for cmma,
which is also called directly from the load IPL code.

The reset functionality is needed to reset the cmma state of the guest
pages, e.g. if a system reset is triggered via qemu monitor; otherwise
this could result in data corruption.

A guest triggered reboot may now lead to multiple cmma resets; this is
OK, however, as this is slowpath anyway and the simplest way to achieve
the intended effects.

If we run with an old kernel that does not support KVM_CAP_IRQ_ROUTING,
we don't have to do anything in the ->register_io_adapter and
->io_adapter_map callbacks and therefore should return 0 instead of
-ENOSYS (just as the non-kvm flic does).

This fixes using adapter interrupts when running under an older kernel,
which broke with "s390x: add I/O adapter registration".

We should not try to store the emw portion of the irb if extended
measurements are not applicable. In particular, we should not surprise
the guest by storing a larger irb if it did not enable extended
measurements.
