target/arm: Implement MVE integer vector-vs-scalar comparisons
Implement the MVE integer vector comparison instructions that compare
each element against a scalar from a general purpose register. These

encodings T4, T5 and T6.
We have to move the decodetree pattern for VPST, because it
overlaps with VCMP T4 with size = 0b11.

target/arm: Implement MVE VMULL (polynomial)
Implement the MVE VMULL (polynomial) insn. Unlike Neon, this comes
in two flavours: 8x8->16 and a 16x16->32. Also unlike Neon, the
inputs are in either the low or the high half of each double-width
element.
The assembler for this insn indicates the size with "P8" or "P16",
encoded into bit 28 as size = 0 or 1. We choose to follow the
same encoding as VQDMULL and decode this into a->size as MO_16

carries through to the helper function names where it then
matches up with the existing pmull_h() which does an 8x8->16
operation and a new pmull_w() which does the 16x16->32.

target/arm: Fix 48-bit saturating shifts
In do_sqrshl48_d() and do_uqrshl48_d() we got some of the edge
cases wrong and failed to saturate correctly:
(1) In do_sqrshl48_d() we used the same code that do_shrshl_bhs()
does to obtain the saturated most-negative and most-positive 48-bit
signed values for the large-shift-left case. This gives (1 << 47)
for saturate-to-most-negative, but we weren't sign-extending this
value to the 64-bit output as the pseudocode requires.
(2) For left shifts by less than 48, we copied the "8/16 bit" code
from do_sqrshl_bhs() and do_uqrshl_bhs(). This doesn't do the right
thing because it assumes the C type we're working with is at least
twice the number of bits we're saturating to (so that a shift left by
bits-1 can't shift anything off the top of the value). This isn't
true for bits == 48, so we would incorrectly return 0 rather than the
most-positive value for situations like "shift (1 << 44) right by
20". Instead check for saturation by doing the shift and signextend
and then testing whether shifting back left again gives the original
value.

target/arm: Fix mask handling for MVE narrowing operations
In the MVE helpers for the narrowing operations (DO_VSHRN and
DO_VSHRN_SAT) we were using the wrong bits of the predicate mask for
the 'top' versions of the insn. This is because the loop works over
the double-sized input elements and shifts the predicate mask by that
many bits each time, but when we write out the half-sized output we
must look at the mask bits for whichever half of the element we are
writing to.
Correct this by shifting the whole mask right by ESIZE bits for the
'top' insns. This allows us also to simplify the saturation bit
checking (where we had noticed that we needed to look at a different
mask bit for the 'top' insn.)

fuzz: avoid building twice, when running on gitlab
On oss-fuzz, we build twice, to put together a build that is portable to
the runner containers. On gitlab ci, this is wasteful and contributes to
timeouts on the build-oss-fuzz job. Avoid building twice on gitlab, at
the remote cost of potentially missing some cases that break oss-fuzz

The windows cross builds still take way too long in gitlab CI, so need
more targets to be skipped. We don't want to hurt coverage of other

The audio migration vmstate is empty, and always has been; we can't
just remove it though because an old qemu might send it us.
Changes with -audiodev now mean it's sometimes created when it didn't

Change it so that vmstate_audio is never sent; if it's received it
should still be accepted, and old qemu's shouldn't be too upset if it's

Commit
584af1f1d9 ("ui/gtk: add a keyboard fifo to the VTE
consoles") changed the VTE chardev backend code to rely on the
chr_accept_input() callback function. The code expects a
chr_accept_input() call whenever qemu_chr_be_can_write() bytes
were written. It turns out this is wrong. Some chardev
frontends only call this callback after can_write was 0.
Change the code to send data until the keyboard fifo is empty

meson: fix logic for gnutls check
The logic before was
if not get_option('gnutls').auto() or have_system
Which is equivalent to
if get_option('gnutls').enabled() or get_option('gnutls').disabled() or have_system
This means that the check for gnutls is performed even if gnutls is
disabled, which means that the build system will insist on having
libtasn1 if gnutls is found, even if gnutls support is disabled.
When gnutls is disabled, the check for gnutls shouldn't be performed,
to ensure that further build system logic (like the check for
libtasn1) doesn't make decisions based on the presence of gnutls,
rather than the gnutls option.
After making this change, I can successfully ./configure --disable-gnutls
on my system with gnutls installed, but not libtasn1.

Later, commit

Revert "acpi/gpex: Inform os to keep firmware resource map"
This reverts commit
0cf8882fd06ba0aeb1e90fa6f23fce85504d7e14.
Which this commit, with aarch64 when using efi PCI devices with IO ports
do not work. The reason is that EFI creates I/O port mappings below
0x1000 (in fact, at 0). However Linux, for legacy reasons, does not
support I/O ports <= 0x1000 on PCI, so the I/O assignment created by EFI
is rejected.
EFI creates the mappings primarily for itself, and up until DSM #5
started to be enforced, all PCI resource allocations that existed at
boot were ignored by Linux and recreated from scratch.
Also, the commit in question looks dubious - it seems unlikely that
Linux would fail to create a resource tree. What does
happen is that BARs get moved around, which may cause trouble in some
cases: for instance, Linux had to add special code to the EFI framebuffer
driver to copy with framebuffer BARs being relocated.
DSM #5 has a long history of debate and misinterpretation.

ACPI Error: Aborting method \_GPE._E01 due to previous error (AE_NOT_FOUND) (
20201113/psparse-531)
ACPI Error: AE_NOT_FOUND, while evaluating GPE method [_E01] (
20201113/evgpe-515)
cause is that QEMU's ACPI hotplug never supported functions other then 0
and due to bug it was generating notification entries for not described
functions.
Technically there is no reason not to describe cold-plugged bridges
(root ports) on functions other then 0, as they similarly to bridge
on function 0 are unpluggable.
So since we need to describe multifunction devices iterate over
fuctions as well. But describe only cold-plugged bridges[root ports]
on functions other than 0 as well.

hw/pcie-root-port: Fix hotplug for PCI devices requiring IO
Q35 has now ACPI hotplug enabled by default for PCI(e) devices.
As opposed to native PCIe hotplug, guests like Fedora 34
will not assign IO range to pcie-root-ports not supporting
native hotplug, resulting into a regression.
Reproduce by:
qemu-bin -M q35 -device pcie-root-port,id=p1 -monitor stdio
device_add e1000,bus=p1
In the Guest OS the respective pcie-root-port will have the IO range
disabled.
Fix it by setting the "reserve-io" hint capability of the
pcie-root-ports so the firmware will allocate the IO range instead.

block: Fix in_flight leak in request padding error path
When bdrv_pad_request() fails in bdrv_co_preadv_part(), bs->in_flight
has been increased, but is never decreased again. This leads to a hang
when trying to drain the block node.
This bug was observed with Windows guests which issue a request that
fully uses IOV_MAX during installation, so that when padding is
necessary (O_DIRECT with a 4k sector size block device on the host),
adding another entry causes failure.
Call bdrv_dec_in_flight() to fix this. There is a larger problem to
solve here because this request shouldn't even fail, but Windows doesn't
seem to care and with this minimal fix the installation succeeds. So
given that we're already in freeze, let's take this minimal fix for 6.1.

linux-user/s390x: signal with SIGFPE on compare-and-trap
Currently when a compare-and-trap instruction is executed, qemu will
always raise a SIGILL signal. On real hardware, a SIGFPE is raised.
Change the PGM_DATA case in cpu_loop to follow the behavior in
linux kernel /arch/s390/kernel/traps.c.
* Only raise SIGILL if DXC == 0
* If DXC matches a non-simulated IEEE exception, raise SIGFPE with
correct si_code
* Raise SIGFPE with si_code == 0 for everything else

target/s390x: Fix SIGILL and SIGFPE psw.addr reporting
For SIGILL, SIGFPE and SIGTRAP the PSW must point after the

Fix by advancing psw.addr for these signals.

qga-win/msi: fix missing libstdc++-6 DLL in MSI installer
libstdc++ is required for the qga-vss.dll that provides fsfreeze
functionality. Currently it is not provided by the MSI installer,
resulting in fsfreeze being disabled in guest environments where it has
not been installed by other means.
In the future this would be better handled via gcc-cpp ComponentGroup
provided by msitools, but that would be better handled with a general
rework of DLL dependency handling in the installer build. Keep it
simple for now to fix this regression.
Tested with Fedora 34 mingw build environment.
