This patch specifies and implements the master/slave communication
to support device IOTLB in slave.
The vhost_iotlb_msg structure introduced for kernel backends is
re-used, making the design close between the two backends.
An exception is the use of the secondary channel to enable the
slave to send IOTLB miss requests to the master.

Since commit d4c19cdeeb ("virtio-serial:
add missing virtio_detach_element() call") the following commands may
cause QEMU to segfault:
$ qemu -M accel=kvm -cpu host -m 1G \
-drive if=virtio,file=test.img,format=raw \
-device virtio-serial-pci,id=virtio-serial0 \
-chardev socket,id=channel1,path=/tmp/chardev.sock,server,nowait \
-device virtserialport,chardev=channel1,bus=virtio-serial0.0,id=port1
$ nc -U /tmp/chardev.sock
^C
(guest)$ cat /dev/zero >/dev/vport0p1
The segfault is non-deterministic: if the event loop notices the socket
has been closed then there is no crash. The disconnect has to happen
right before QEMU attempts to write data to the socket.
The backtrace is as follows:
Thread 1 "qemu-system-x86" received signal SIGSEGV, Segmentation fault.

The do_flush_queued_data() function does not anticipate chardev close
events during vsc->have_data(). It expects port->elem to remain
non-NULL for the duration its for loop.
The fix is simply to return from do_flush_queued_data() if the port
closes because the close event already frees port->elem and drains the
virtqueue - there is nothing left for do_flush_queued_data() to do.

Virtio serial device controls the lifetime of virtio-serial-bus and
virtio-serial-bus links back to the device via its hotplug-handler
property. This extra ref-count prevents the device from getting
finalized, leaving the VirtIODevice memory listener registered and
leading to use-after-free later on.
This patch addresses the same issue as Fam Zheng's
"virtio-scsi: Unset hotplug handler when unrealize"
only for a different virtio device.

The M series MPU is almost the same as the already implemented R
profile MPU (v7 PMSA). So all we need to implement here is the MPU
register interface in the system register space.
This implementation has the same restriction as the R profile MPU
that it doesn't permit regions to be sized down smaller than 1K.
We also do not yet implement support for MPU_CTRL.HFNMIENA; this
bit should if zero disable use of the MPU when running HardFault,
NMI or with FAULTMASK set to 1 (ie at an execution priority of
less than zero) -- if the MPU is enabled we don't treat these
cases any differently.

When we calculate the mask to use to get the group priority from
an interrupt priority, the way that NS BPR1 is handled differs
from how BPR0 and S BPR1 work -- a BPR1 value of 1 means
the group priority is in bits [7:1], whereas for BPR0 and S BPR1
this is indicated by a 0 BPR value.
Subtract 1 from the BPR value before creating the mask if
we're using the NS BPR value, for both hardware and virtual
interrupts, as the GICv3 pseudocode does, and fix the comments
accordingly.

icc_bpr_write() was not enforcing that writing a value below the
minimum for the BPR should behave as if the BPR was set to the
minimum value. This doesn't make a difference for the secure
BPRs (since we define the minimum for the QEMU implementation
as zero) but did mean we were allowing the NS BPR1 to be set to
0 when 1 should be the lowest value.

Assorted accumulated patches. These are nearly all bugfixes at one
level or another - some for longstanding problems, others for some
regressions caused by more recent cleanups.
This includes preliminary patches towards fixing migration for Radix
Page Table guests under POWER9 and also fixing some migration
regressions due to the re-organization of the interrupt controller
code. Not all the pieces are there yet, so those still won't quite
work, but the preliminary changes make sense on their own.

ehci registers ehci_frame_timer as both timer and bottom half, which
turned out to be a bad idea as it can be called as bottom half then
while it is running as timer, and it isn't prepared to handle recursive
calls.
Change the timer func to just schedule the bottom half to avoid this.

PORT_STAT_C_SUSPEND should be set even on host-initiated wake-up,
i.e. on ClearPortFeature(PORT_SUSPEND). Windows is known to not
work properly otherwise.
Side note, since PORT_ENABLE looks similar and might appear to
have the same issue: According to 11.24.2.7.2.2 C_PORT_ENABLE:
"This bit is set when the PORT_ENABLE bit changes from one to
zero as a result of a Port Error condition (see Section 11.8.1).
This bit is not set on any other changes to PORT_ENABLE."

In case the frame timer doesn't run for a while due to the host being
busy skipped_uframes can become big enough that UFRAME_TIMER_NS *
skipped_uframes overflows. Which in turn throws off all subsequent
ehci frame timer calculations.

For reasons unknown, Windows won't online all memory, both at command
line and hot-plugged later, unless the hotplug mem hole SRAT entry
specifies a node greater than or equal to the ones where memory is
added.
Using the highest node on the machine makes recent versions of Windows
happy.
With this example command line:
... \
-m 1024,slots=4,maxmem=32G \
-numa node,nodeid=0 \
-numa node,nodeid=1 \
-numa node,nodeid=2 \
-numa node,nodeid=3 \
-object memory-backend-ram,size=1G,id=mem-mem1 \
-device pc-dimm,id=dimm-mem1,memdev=mem-mem1,node=1
Windows reports a total of 1G of RAM without this commit and the expected
2G with this commit.
