POWER9 (arch v3) slightly changes the HPTE format. The B bits move
from the first to the second half of the HPTE, and the AVPN/ARPN
are slightly shorter.
However, under SPAPR, the hypercalls still take the old format
(and probably will for the foreseable future).
The simplest way to support this is thus to convert the HPTEs from
new to old format when reading them if the MMU model is v3 and there
is no virtual hypervisor, leaving the rest of the code unchanged.

With mttcg, we can have MMU lookups happening at the same time
as the guest modifying the page tables.
Since the HPTEs of the hash table MMU contains two words (or
double worlds on 64-bit), we need to make sure we read them
in the right order, with the correct memory barrier.
Additionally, when using emulated SPAPR mode, the hypercalls
writing to the hash table must also perform the udpates in
the right order.

Historically the 64-bit server MMU supports two way of configuring the
guest "real mode" mapping:
- The "RMA" with is a single chunk of physically contiguous
memory remapped as guest real, and controlled by the RMLS
field in the LPCR register and the RMOR register.
- The "VRMA" which uses special PTEs inserted in the partition
hash table by the hypervisor.
POWER9 deprecates the former, which is reflected by the filtering
done in ppc_store_lpcr() which effectively prevents setting of
the RMLS field.
However, when using fully emulated SPAPR machines, our qemu code
currently only knows how to define the guest real mode memory using
RMLS.
Thus you cannot run a SPAPR machine anymore with a POWER9 CPU
model today.
This works around it with a quirk in ppc_store_lpcr() to continue
allowing the RMLS field to be set when using a virtual hypervisor.
Ultimately we will want to implement configuring a VRMA instead
which will also be necessary if we want to migrate a SPAPR guest
between TCG and KVM but this is a lot more work.

The HW relies on LPCR:HR along with the PATE to determine whether
to use Radix or Hash mode. In fact it uses LPCR:HR more commonly
than the PATE.
For us, it's also more efficient to do so, especially since unlike
the HW we do not maintain a cache of the current PATE and HV PATE
in a generic place.
Prepare the grounds for that by ensuring that LPCR:HR is set
properly on SPAPR machines.
Another option would have been to use a callback to get the PATE
but this gets messy when implementing bare metal support, it's
much simpler (and faster) to use LPCR.
Since existing migration streams may not have it, fix it up in
spapr_post_load() as well based on the pseudo-PATE entry that
we keep.

The issue with testing asynchronous unplug requests it that they usually
require a running guest to handle the request. However, to test if
unplug of PCI devices works, we can apply a nice little trick on some
architectures:
On system reset, x86 ACPI, s390x and spapr will perform the unplug,
resulting in the device of interest to get deleted and a DEVICE_DELETED
event getting sent.
On s390x, we still get a warning
qemu-system-s390x: -device virtio-mouse-pci,id=dev0:
warning: Plugging a PCI/zPCI device without the 'zpci' CPU feature
enabled; the guest will not be able to see/use this device
This will be fixed soon, when we enable the zpci CPU feature always
(Conny already has a patch for this queued).

It's very easy for the CPU specific has_work() implementation
and the logic in ppc_hw_interrupt() to be subtly out of sync.
This can occasionally allow a CPU to wakeup from a PM state
and resume executing past the PM instruction when it should
resume at the 0x100 vector.
This detects if it happens and aborts, making it a lot easier
to catch such bugs when testing rather than chasing obscure
guest misbehaviour.

STOP must act differently based on PSSCR:EC on POWER9. When set, it
acts like the P7/P8 power management instructions and wake up at 0x100
based on the wakeup conditions in LPCR.
When PSSCR:EC is clear however it will wakeup at the next instruction
after STOP (if EE is clear) or take the corresponding interrupts (if
EE is set).

When issuing a power management instruction, we set MSR:EE
to force ppc_hw_interrupt() into calling powerpc_excp()
to deal with the fact that on P7 and P8, the system reset
caused by the wakeup needs to be generated regardless of
the MSR:EE value (using LPCR only).
This however means that the OS will see a bogus SRR1:EE
value which is a problem. It also prevents properly
implementing P9 STOP "light".
So fix this by instead putting some logic in ppc_hw_interrupt()
to decide whether to deliver or not by taking into account the
fact that we are waking up from sleep.
The LPCR isn't checked as this is done in the has_work() test.

Those instructions currently raise an exception from within
the helper. This tends to result in a bogus nip value in
the env context (typically the beginning of the TB). Such
a helper needs a gen_update_nip() first.
This fixes it with a different approach which is to throw the
exception from translate.c instead of the helper using
gen_exception_nip() which does the right thing. Exception
EXCP_HLT is also used instead of POWERPC_EXCP_STOP to effectively
exit from the CPU execution loop.

Adding a telnet monitor for no real purpose on a fixed port is not so
great. Just use a null monitor instead.

filter_qmp_testfiles() currently filters the filename only for specific
keys. However, there are more keys that take filenames (such as
block-commit's @top and @base, or ssh's @path), and it does not make
sense to list them all here. "$TEST_DIR/$PID-" should have enough
entropy not to appear anywhere randomly.

On Python 2.x, strings are not always unicode strings. This function
checks whether a given value is a plain string, or a unicode string (if
there is a difference).

With IMGOPTSSYNTAX, $TEST_IMG is useless for this test (it only tests
the file-posix protocol driver). Therefore, if $TEST_IMG_FILE is set,
use that instead.
Because this test requires the file protocol, $TEST_IMG_FILE will always
be set if $IMGOPTSSYNTAX is true.

math.ceil() returns an integer on Python 3.x, but a float on Python 2.x.
range() always needs integers, so we need an explicit conversion on 2.x
(which does not hurt on 3.x).
It is not quite clear whether we want to support Python 2.x for any
prolonged time, but this may as well be fixed along with the other
issues some iotests have right now.

A previous commit removed the default filters for qmp_log with the
intention to make them explicit; but this happened only for test 206.
There are more tests (for more exotic image formats than qcow2) which
require the filename filter, though.
Note that 237 is still broken for Python 2.x, which is fixed in the next
commit.

When BDSs are created by qemu itself (e.g. as filters in block jobs),
they may not have a "driver" option in their options QDict. When
generating a json:{} filename, however, it must always be present.

a strong option so not being able to should not stop us from generating

Both of the defaults we currently have in the curl driver are named
based on a slightly different schema, let's unify that and call both
CURL_BLOCK_OPT_${NAME}_DEFAULT.
While at it, we can add a macro for the third option for which a default
exists, namely "sslverify".

Currently, nvme's bdrv_refresh_filename() is an exact copy of null's
implementation. However, for null, "null-co://" and "null-aio://" are
indeed valid filenames -- for nvme, they are not, as a device address is
still required.
The correct implementation should generate a filename of the form
"nvme://[PCI address]/[namespace]" (as the comment above
nvme_parse_filename() describes).

If a format BDS's file BDS is in turn a format BDS, we cannot simply use
the same filename, because when opening a BDS tree based on a filename
alone, qemu will create only one format node on top of one protocol node
(disregarding a potential backing file).
