tcg_s390_tod_updated() is always called with the iothread being locked
(e.g. from S390TODClass->set() e.g. via HELPER(sck) or on incoming
migration). The helper we call takes the lock itself - bad.
Let's change that by factoring out updating the ckc timer. This now looks
much nicer than having to call a helper from another function.
While touching it we also make sure that env->ckc is updated even if the
new value is -1ULL, for now it would not have been modified in that case.

Let's do this for completeness reason, although we don't support e.g.
PCDIMM/NVDIMM, which would use the alignment for placing the memory
region in guest physical memory. But maybe someday we would want to
support something like this - then we don't forget about this if
allowing multiple allocations in legacy_s390_alloc().
Use the same alignment as we would set in qemu_anon_ram_alloc(). Our
fixed address satisfies this alignment (1MB). This implicitly sets the
alignment of the underlying memory region.

We always allocate at a fixed address, a second allocation can therefore
of course never work. We would simply overwrite mappings.
This can e.g. happen in s390_memory_init(), if trying to allocate more

run_on_cpu() doesn't seem to work reliably until the CPU has been fully
created if the single-threaded TCG main loop is already running.
Therefore, hotplugging a CPU under single-threaded TCG does currently
not work. We should use the direct call instead of going via
run_on_cpu().
So let's use run_on_cpu() for KVM only - KVM requires it due to the initial
CPU reset ioctl. As a nice side effect, we get rid of the ifdef.

Previously we clean up the queues when we got CLOSED event. It was used
to make sure we won't send leftover replies/events of a old client to a
new client which makes perfect sense. However this will also drop the
replies/events even if the output port of the previous chardev backend
is still open, which can lead to missing of the last replies/events.
Now this patch does an extra operation to flush the response queue
before cleaning up.
In most cases, a QMP session will be based on a bidirectional channel (a
TCP port, for example, we read/write to the same socket handle), so in
port and out port of the backend chardev are fundamentally the same
port. In these cases, it does not really matter much on whether we'll
flush the response queue since flushing will fail anyway. However there
can be cases where in & out ports of the QMP monitor's backend chardev
are separated. Here is an example:
cat $QMP_COMMANDS | qemu -qmp stdio ... | filter_commands
In this case, the backend is fd-typed, and it is connected to stdio
where in port is stdin and out port is stdout. Now if we drop all the
events on the response queue then filter_command process might miss some
events that it might expect. The thing is that, when stdin closes,
stdout might still be there alive!
In practice, I encountered SHUTDOWN event missing when running test with
iotest 087 with Out-Of-Band enabled. Here is one of the ways that this
can happen (after "quit" command is executed and QEMU quits the main
loop):
1. [main thread] QEMU queues a SHUTDOWN event into response queue.
2. "cat" terminates (to distinguish it from the animal, I quote it).
3. [monitor iothread] QEMU's monitor iothread reads EOF from stdin.
4. [monitor iothread] QEMU's monitor iothread calls the CLOSED event
hook for the monitor, which will destroy the response queue of the
monitor, then the SHUTDOWN event is dropped.
5. [main thread] QEMU's main thread cleans up the monitors in
monitor_cleanup(). When trying to flush pending responses, it sees
nothing. SHUTDOWN is lost forever.
Note that before the monitor iothread was introduced, step [4]/[5] could
never happen since the main loop was the only place to detect the EOF
event of stdin and run the CLOSED event hooks. Now things can happen in
parallel in the iothread.
Without this patch, iotest 087 will have ~10% chance to miss the
SHUTDOWN event and fail when with Out-Of-Band enabled:

Leave ARM_CP_SVE, removing ARM_CP_FPU; the sve_access_check
produced by the flag already includes fp_access_check. If
we also check ARM_CP_FPU the double fp_access_check asserts.

We already check for the same condition within the normal integer
sdiv and sdiv64 helpers. Use a slightly different formation that
does not require deducing the expression type.

We don't actually implement SD command CRC checking, because
for almost all of our SD controllers the CRC generation is
done in hardware, and so modelling CRC generation and checking
would be a bit pointless. (The exception is that milkymist-memcard
makes the guest software compute the CRC.)
As a result almost all of our SD controller models don't bother
to set the SDRequest crc field, and the SD card model doesn't
check it. So the tracing of it in sdbus_do_command() provokes
Coverity warnings about use of uninitialized data.
Drop the CRC field from the trace; we can always add it back
if and when we do anything useful with the CRC.
Fixes Coverity issues 1386072, 1386074, 1386076, 1390571.

KVM implies V7VE, which implies ARM_DIV and THUMB_DIV. The conditional
detection here is therefore unnecessary. Because V7VE is already
unconditionally specified for all KVM hosts, ARM_DIV and THUMB_DIV are
already indirectly specified and do not need to be included here at all.

Since kernel commit a86bd139f2 (arm64: arch_timer: Enable CNTVCT_EL0
trap..), released in kernel version v4.12, user-space has been able
to read these system registers. As we can't use QEMUTimer's in
linux-user mode we just directly call cpu_get_clock().
