The task for launching a kernel is quite repetitive: Set the serial
console, set the -kernel and maybe -initrd and -dtb parameters,
launch the VM and then wait for the expected console output. So
it's easier in some tests to provide these steps via a separate
function.

no senmatic change has been introduced. After the commit, the merge
property can be applied even the corresponding memory region isn't
initialized yet. This leads to crash dump by the following command
lines.

Before, the virtio-mem device would unplug all the memory with any reset
of the device, including during the wake-up of the guest from a
suspended state. Due to this, the virtio-mem driver in the Linux kernel
disallowed suspend-to-ram requests in the guest when the
VIRTIO_MEM_F_PERSISTENT_SUSPEND feature is not exposed by QEMU.
This patch adds the code to skip the reset on wake-up and exposes
theVIRTIO_MEM_F_PERSISTENT_SUSPEND feature to the guest kernel driver
when suspending is possible in QEMU (currently only x86).

LegacyReset does not pass ResetType to the reset callback method, which
the new Resettable framework uses. Due to this, virtio-mem cannot use
the new RESET_TYPE_WAKEUP to skip the reset during wake-up from a
suspended state.
This patch adds overrides Resettable interface methods in VirtIOMEMClass
to use the new Resettable framework and replaces
qemu_[un]register_reset() calls with qemu_[un]register_resettable().

Currently, both qemu_devices_reset() and MachineClass::reset() use
ShutdownCause for the reason of the reset. However, the Resettable
interface uses ResetState, so ShutdownCause needs to be translated to
ResetType somewhere. Translating it qemu_devices_reset() makes adding
new reset types harder, as they cannot always be matched to a single
ShutdownCause here, and devices may need to check the ResetType to
determine what to reset and if to reset at all.
This patch moves this translation up in the call stack to
qemu_system_reset() and updates all MachineClass children to use the
ResetType instead.

Virtio memory devices rely on PCI BARs to expose the contents of memory.
Because of this they cannot be used (yet) with virtio-mmio or virtio-ccw.
In fact the code that is common to virtio-mem and virtio-pmem, which
is in hw/virtio/virtio-md-pci.c, is only included if CONFIG_VIRTIO_PCI
is set. Reproduce the same condition in the Kconfig file, only allowing
VIRTIO_MEM and VIRTIO_PMEM to be defined if the transport supports it.
Without this patch it is possible to create a configuration with
CONFIG_VIRTIO_PCI=n and CONFIG_VIRTIO_MEM=y, but that causes a
linking failure.

The XT check for the lxvx/stxvx instructions is currently
inverted. This was introduced during the move to decodetree.
>From the ISA:
Chapter 7. Vector-Scalar Extension Facility
Load VSX Vector Indexed X-form
lxvx XT,RA,RB
if TX=0 & MSR.VSX=0 then VSX_Unavailable()
if TX=1 & MSR.VEC=0 then Vector_Unavailable()
...
Let XT be the value 32×TX + T.
The code currently does the opposite:
if (paired || a->rt >= 32) {
REQUIRE_VSX(ctx);
} else {
REQUIRE_VECTOR(ctx);
}
This was already fixed for lxv/stxv at commit "2cc0e449d1 (target/ppc:
Fix lxv/stxv MSR facility check)", but the indexed forms were missed.
