pseries: Abolish envs array

Currently the pseries machine init code builds up an array, envs, of
CPUState pointers for all the cpus in the system. This is kind of
pointless, given the generic code already has a perfectly good linked list
of the cpus.

In addition, there are a number of places which assume that the cpu's...

Delay creation of pseries device tree until reset

At present, the 'pseries' machine creates a flattened device tree in the

However, the machine->init function runs before processing of -device...

Don't call cpu_synchronize_state() from machine init.

This will deadlock when the I/O thread is used, since the
CPU thread is blocked waiting for qemu_system_ready.

The synchronization is unnecessary since this is before
cpu_synchronize_all_post_init()....

virtio-serial: Enable ioeventfd

Enable ioeventfd for virtio-serial devices by default. Commit
25db9ebe15125deb32958c6df74996f745edf1f9 lists the benefits of using
ioeventfd.

Copying a file from guest to host over a virtio-serial channel didn't
show much difference in time or io_exit rate....

virtio-serial: Don't clear ->have_data() pointer after unplug

After a port unplug operation, the port->info->have_data() pointer was
set to NULL. The problem is, the ->info struct is shared by all ports,
effectively disabling writes to other ports.

virtio-serial: Use a struct to pass config information from proxy

Instead of using a single variable to pass to the virtio_serial_init
function, use a struct so that expanding the number of variables to be
passed on later is easier.

virtio-serial: Disallow generic ports at id 0

Port 0 is reserved for virtconsole devices for backward compatibility

libvirt prior to commit 8e28c5d40200b4c5d483bd585d237b9d870372e5 used
port 0 for generic ports. libvirt will no longer do that, but disallow...
