e2cce18f5c target/arm: Add VHE system register redirection and aliasing
Several of the EL1/0 registers are redirected to the EL2 version when in
EL2 and HCR_EL2.E2H is set.  Many of these registers have side effects.
Link together the two ARMCPRegInfo structures after they have been
properly instantiated.  Install common dispatch routines to all of the
relevant registers.

The same set of registers that are redirected also have additional
EL12/EL02 aliases created to access the original register that was
redirected.

Omit the generic timer registers from redirection here, because we'll
need multiple kinds of redirection from both EL0 and EL2.

Use the correct sctlr for EL2&0 regime.  Due to header ordering,

79cabf1f47 target/arm: Recover 4 bits from TBFLAGs
We had completely run out of TBFLAG bits.
Split A- and M-profile bits into two overlapping buckets.
This results in 4 free bits.

We used to initialize all of the a32 and m32 fields in DisasContext
by assignment, in arm_tr_init_disas_context.  Now we only initialize
either the a32 or m32 by assignment, because the bits overlap in
tbflags.  So zero the entire structure in gen_intermediate_code.

0999a4ba87 target/arm/monitor: query-cpu-model-expansion crashed qemu when using machine type none
Commit e19afd5667 mentioned that target-arm only supports queryable
cpu models 'max', 'host', and the current type when KVM is in use.
The logic works well until using machine type none.

For machine type none, cpu_type will be null if cpu option is not
set by command line, strlen(cpu_type) will terminate process.
So We add a check above it.

This won't affect i386 and s390x since they do not use current_cpu.

416b71906e docs: stop documenting the e1000 NIC model as the default
The default NIC model for QEMU varies per machine type, and is liable to
change across machine type versions. Documenting e1000 NIC as the
default for PC/i386 is thus misleading to users at best. In particular
the PC q35 machine type switched to use e1000e, but only in machine
type versions after 2.11.

Rather than try to explain which NIC model is used for each machine
type version, remove mention of e1000 as the default, and steer users
towards always specifying their desired model.

c64e1e7538 io/channel-websock: treat 'binary' and no sub-protocol as the same
noVNC doesn't use 'binary' protocol by default after
commit c912230309806aacbae4295faf7ad6406da97617.

It will cause qemu return 400 when handshaking.

To overcome this problem and remain compatibility of
older noVNC client.

We treat 'binary' and no sub-protocol as the same
so that we can support different version of noVNC
client.

Tested on noVNC before c912230 and after c912230.

29d62771c8 hw/vfio: Move the IGD quirk code to a separate file
The IGD quirk code defines a separate device, the so-called
"vfio-pci-igd-lpc-bridge" which shows up as a user-creatable
device in all QEMU binaries that include the vfio code. This
is a little bit unfortunate for two reasons: First, this device
is completely useless in binaries like qemu-system-s390x.
Second we also would like to disable it in downstream RHEL
which currently requires some extra patches there since the
device does not have a proper Kconfig-style switch yet.

So it would be good if the device could be disabled more easily,
thus let's move the code to a separate file instead and introduce
a proper Kconfig switch for it which gets only enabled by default
if we also have CONFIG_PC_PCI enabled.

ed2a4a7941 audio: proper support for float samples in mixeng
This adds proper support for float samples in mixeng by adding a new
audio format for it.

Limitations: only native endianness is supported.  None of the virtual
sound cards support float samples (it looks like most of them only
support 8 and 16 bit, only hda supports 32 bit), it is only used for the
audio backends (i.e. host side).

180b044ffd coreaudio: fix coreaudio playback
There are reports that since commit 2ceb8240fa "coreaudio: port
to the new audio backend api" audio playback with CoreAudio is
broken. This patch reverts some parts the commit.

Because of changes in the audio subsystem the audio clip
function in v4.1.0 of coreaudio.c had to be moved to mixeng.c
and the generic buffer management code needed a hint about the
size of the float type.

This patch is based on a patch from Zoltán Kővágó found at
https://lists.nongnu.org/archive/html/qemu-devel/2020-01/msg02142.html.

We can't access top after call bdrv_backup_top_drop, as it is already
freed at this time.

Also, no needs to unref target child by hand, it will be unrefed on
bdrv_close() automatically.

So, just do bdrv_backup_top_drop if append succeed and one bdrv_unref
otherwise.

Note, that in !appended case bdrv_unref(top) moved into drained section
on source. It doesn't really matter, but just for code simplicity.

da86f8cbad qcow2: Use bs->bl.request_alignment when updating an L1 entry
When updating an L1 entry the qcow2 driver writes a (512-byte) sector
worth of data to avoid a read-modify-write cycle. Instead of always
writing 512 bytes we should follow the alignment requirements of the
storage backend.

(the only exception is when the alignment is larger than the cluster
size because then we could be overwriting data after the L1 table)

ce95a15e42 iotests: Enable more tests in the 'auto' group to improve test coverage
According to Kevin, tests 030, 040 and 041 are among the most valuable
tests that we have, so we should always run them if possible, even if
they take a little bit longer.

According to Max, it would be good to have a test for iothreads and
migration. 127 and 256 seem to be good candidates for iothreads. For
migration, let's enable 181 and 203 (which also tests iothreads).
(091 would be a good candidate for migration, too, but Alex Bennée
reported that this test fails on ZFS file systems, so it can't be
included yet)

cd2058289b iotests: Skip Python-based tests if QEMU does not support virtio-blk
We are going to enable some of the python-based tests in the "auto" group,
and these tests require virtio-blk to work properly. Running iotests
without virtio-blk likely does not make too much sense anyway, so instead
of adding a check for the availability of virtio-blk to each and every
test (which does not sound very appealing), let's rather add a check for
this a central spot in the "check" script instead (so that it is still
possible to run "make check" for qemu-system-tricore for example).
