The test whether the chardev is an AF_UNIX socket rejects
"-chardev socket,id=chr0,path=/tmp/foo,server,nowait -device
ivshmem,chardev=chr0", but fails to explain why.
Use an explicit error on why a chardev may be rejected.
max_peer isn't really useful, it tracks the maximum received VM id, but
that quickly matches nb_peers, the size of the peers array. Since VM
come and go, there might be sparse peers so it doesn't help much in
general to have this value around.
Use the latest qemu device modeling API, in particular, convert to
realize to fix the error handling; right now a botched device_add
ivhsmem command kills the VM.
If a chardev is allowed to be created outside of QMP, then it must be
also possible to free it. This is useful for ivshmem that creates
chardev anonymously and must be able to free them.

BlockAcctStats contains statistics about the data transferred from and

Furthermore, those statistics are supposed to be specific for a certain

bdrv_get_stats()); on the other hand, wr_highest_sector may be a rather
important information to know for each BDS. When BlockAcctStats is
finally removed from the BDS, we will want to keep wr_highest_sector in
the BDS.
Finally, wr_highest_sector is renamed to wr_highest_offset and given the
appropriate meaning. Externally, it is represented as an offset so there
is no point in doing something different internally. Its definition is
changed to match that in qapi/block-core.json which is "the offset after
the greatest byte written to". Doing so should not cause any harm since
if external programs tried to calculate the volume usage by
(wr_highest_offset + 512) / volume_size, after this patch they will just
assume the volume to be full slightly earlier than before.

LoPAPR defines a "ibm,pa-features" per-CPU device tree property which
describes extended features of the Processor Architecture.
This adds the property to the device tree. At the moment this is the
copy of what pHyp advertises except "I=1 (cache inhibited) Large Pages"
which is enabled for TCG and disabled when running under HV KVM host
with 4K system page size.

g_malloc0 already clears the memory, so no need for
the additional memset here.
