Add ProxyMemoryListener object which is used to keep the view of the RAM
in sync between QEMU and remote process.
A MemoryListener is registered for system-memory AddressSpace. The
listener sends SYNC_SYSMEM message to the remote process when memory
listener commits the changes to memory, the remote process receives
the message and processes it in the handler for SYNC_SYSMEM message.

Per MPC8548ERM [1] chapter 14.5.3.4.1:
When RCTRL.RSF is 1, frames less than 64 bytes are accepted upon
a DA match. But currently QEMU does the opposite. This commit
reverses the RCTRL.RSF testing logic to match the manual.
Due to the reverse of the logic, certain guests may potentially
break if they don't program eTSEC to have RCTRL.RSF bit set.
When RCTRL.RSF is 0, short frames are silently dropped, however
as of today both slirp and tap networking do not pad short frames
(e.g.: an ARP packet) to the minimum frame size of 60 bytes. So
ARP requests will be dropped, preventing the guest from becoming
visible on the network.
The same issue was reported on e1000 and vmxenet3 before, see:
commit 78aeb23ede ("e1000: Pad short frames to minimum size (60 bytes)")
commit 40a87c6c9b ("vmxnet3: Pad short frames to minimum size (60 bytes)")

The current logic for calculating 'maxdomain' making it a sum of
numa_state->num_nodes with spapr->gpu_numa_id. spapr->gpu_numa_id is
used as a index to determine the next available NUMA id that a
given NVGPU can use.
The problem is that the initial value of gpu_numa_id, for any topology
that has more than one NUMA node, is equal to numa_state->num_nodes.
This means that our maxdomain will always be, at least, twice the
amount of existing NUMA nodes. This means that a guest with 4 NUMA
nodes will end up with the following max-associativity-domains:
rtas/ibm,max-associativity-domains
00000004 00000008 00000008 00000008 00000008
This overtuning of maxdomains doesn't go unnoticed in the guest, being
detected in SLUB during boot:
dmesg | grep SLUB
[ 0.000000] SLUB: HWalign=128, Order=0-3, MinObjects=0, CPUs=4, Nodes=8
SLUB is detecting 8 total nodes, with 4 nodes being online.
This patch fixes ibm,max-associativity-domains by considering the amount
of NVGPUs NUMA nodes presented in the guest, instead of just
spapr->gpu_numa_id.

On PowerNV systems, the BMC is in charge of mapping the PNOR contents
on the LPC FW address space using the HIOMAP protocol. Under QEMU, we
emulate this behavior and we also add an extra control on the flash
accesses by letting the HIOMAP command handler decide whether the
memory region is accessible or not depending on the firmware requests.
However, this behavior is not compatible with hostboot like firmwares
which need this mapping to be always available. For this reason, the
PNOR memory region is initially disabled for skiboot mode only.
This is badly placed under the LPC model and requires the use of the
machine. Since it doesn't add much, simply remove the initial setting.
The extra control in the HIOMAP command handler will still be performed.

The device tree handed over by QEMU to SLOF indeed contains:
qemu,boot-list =
"/pci@800000020000000/usb@0/storage@1/disk@101000000000000 HALT";
but the device node is named usb-xhci@0, not usb@0.
This happens because the firmware names of PCI devices returned
by get_boot_devices_list() come from pcibus_get_fw_dev_path(),
while the sPAPR PHB code uses a different naming scheme for
device nodes. This inconsistency has always been there but it was
hidden for a long time because SLOF used to rename USB device
nodes, until this commit, merged in QEMU 4.2.0 :

In the CPU hotunplug bug [1] the guest kernel throws a scary
message in dmesg:
pseries-hotplug-cpu: Failed to offline CPU <NULL>, rc: -16
The reason isn't related to the bug though. This happens because the
kernel file arch/powerpc/platform/pseries/hotplug-cpu.c, function
dlpar_cpu_remove(), is not finding the device_node.name of the offending
CPU.
We're not populating the 'name' property for hotplugged CPUs. Since the
kernel relies on device_node.name for identifying CPU nodes, and the
CPUs that are coldplugged has the 'name' property filled by SLOF, this
is creating an unneeded inconsistency between hotplug and coldplug CPUs
in the kernel.
Let's fill the 'name' property for hotplugged CPUs as well. This will
make the guest dmesg throws a less intimidating message when we try to
unplug the last online CPU:

Refactor the zone write check logic such that the most "meaningful"
error is returned first. That is, first, if the zone is not writable,
return an appropriate status code for that. Then, make sure we are
actually writing at the write pointer and finally check that we do not
cross the zone write boundary. This aligns with the "priority" of status
codes for zone read checks.
Also add a couple of additional descriptive trace events and remove an
always true assert.

When a zone append is processed the controller checks that validity of
the write before assigning the LBA to the append command. This causes
the boundary check to be wrong.
Fix this by checking the write *after* assigning the LBA. Remove the
append special case from the nvme_check_zone_write and open code it in
nvme_do_write, assigning the slba when basic sanity checks have been
performed. Then check the validity of the resulting write like any other
write command.
In the process, also fix a missing endianness conversion for the zone
append ALBA.

Currently, no features are saveable, so the current check is not wrong,
but add a check against the feature capabilities to make sure this will
not regress if saveable features are added later.
