Patch logs MCE AO, AR messages injected to guest or taken by QEMU itself.
We print the QEMU address for guest MCEs, helps on hypervisors that have
another source of MCE logging like mce log, and when they go missing.
For example we found these QEMU logs:
September 26th 2019, 17:36:02.309 Droplet-153258224: Guest MCE Memory Error at qemu addr 0x7f8ce14f5000 and guest 3d6f5000 addr of type BUS_MCEERR_AR injected qemu-system-x86_64 amsN ams3nodeNNNN
September 27th 2019, 06:25:03.234 Droplet-153258224: Guest MCE Memory Error at qemu addr 0x7f8ce14f5000 and guest 3d6f5000 addr of type BUS_MCEERR_AR injected qemu-system-x86_64 amsN ams3nodeNNNN
The first log had a corresponding mce log entry, the second didnt (logging
thresholds) we can infer from second entry same PA and mce type.

If we try to start QEMU with "-k en-us", qemu prints a message and exits
with:
qemu-system-i386: could not read keymap file: 'en-us'
It's because this function is called way too early, before
qemu_add_data_dir() is called, and so qemu_find_file() fails.
To fix that, move init_keyboard_layout() from the class init function to the
instance init function.

The current code does not correctly pass the color pair information to

This patch fixes this by using PAIR_NUMBER() to retrieve the color pair

macOS API documentation says that before applicationDidFinishLaunching
is called, any events will not be processed. However, some events are
fired before it is called in macOS Catalina. This causes deadlock of
iothread_lock in handleEvent while it will be released after the
app_started_sem is posted.
This patch avoids processing events before the app_started_sem is
posted to prevent this deadlock.

With stereo playback, they need about 375 minutes of continuous audio
playback to overflow, which is usually not a problem (as stopping and
later resuming playback resets the counters). But with 7.1 audio, they
only need about 95 minutes to overflow.
After the overflow, the buf->prod % USBAUDIO_PACKET_SIZE(channels)
assertion no longer holds true, which will result in overflowing the
buffer. With 64 bit variables, it would take about 762000 years to
overflow.

This will allow us to disable mixeng when we use a decent backend.
Disabling mixeng have a few advantages:
* we no longer convert the audio output from one format to another, when
the underlying audio system would just convert it to a third format.
We no longer convert, only the underlying system, when needed.
* the underlying system probably has better resampling and sample format
converting methods anyway...
* we may support formats that the mixeng currently does not support (S24
or float samples, more than two channels)
* when using an audio server (like pulseaudio) different sound card
outputs will show up as separate streams, even if we use only one
backend
Disadvantages:
* audio capturing no longer works (wavcapture, and vnc audio extension)
* some backends only support a single playback stream or very picky
about the audio format. In this case we can't disable mixeng.
Originally thw two main use cases of the disabled option was: using
unsupported audio formats (5.1 and 7.1 audio) and having different
pulseaudio streams per audio frontend. Since we can have multiple
-audiodevs, the latter is not that important, so currently you only need
this option if you want to use 5.1 or 7.1 audio (implemented in a later
patch), otherwise it's probably better to stick to the old and tried
mixeng, since it's less picky about the backends.
The ideal solution would be to port as much as possible to gstreamer,
but this is currently out of scope:

qcow2_reopen_bitmaps_ro wants to store bitmaps and then mark them all
readonly. But the latter don't work, as
qcow2_store_persistent_dirty_bitmaps removes bitmaps after storing.
It's OK for inactivation but bad idea for reopen-ro. And this leads to
the following bug:
Assume we have persistent bitmap 'bitmap0'.
Create external snapshot
bitmap0 is stored and therefore removed
Commit snapshot
now we have no bitmaps
Do some writes from guest (*)
they are not marked in bitmap
Shutdown
Start
bitmap0 is loaded as valid, but it is actually broken! It misses
writes (*)
Incremental backup
it will be inconsistent
So, let's stop removing bitmaps on reopen-ro. But don't rejoice:
reopening bitmaps to rw is broken too, so the whole scenario will not
work after this patch and we can't enable corresponding test cases in
260 iotests still. Reopening bitmaps rw will be fixed in the following
patches.

It may provoke bugs, like in recently fixed write-blocking mode of

there are possible unrelated dirty bytes, covered by rounded-up region
and information of this unrelated "dirtiness" will be lost.
Make hbitmap_reset strict: assert that arguments are aligned, allowing

sphinx-build is buggy when multiple processes are using the same
doctree directory in parallel. See the 3-year-old Sphinx bug
report at: https://github.com/sphinx-doc/sphinx/issues/2946
Instead of avoiding parallel builds or adding some kind of
locking, I'm using the simplest solution: just using a different
doctree cache for each builder.

Add new version of Snowridge CPU model that removes MPX feature.
MPX support is being phased out by Intel. GCC has dropped it, Linux kernel
and KVM are also going to do that in the future.

KVM has a 80-entry limit at KVM_SET_CPUID2. With the
introduction of CPUID[0x1F], it is now possible to hit this limit
with unusual CPU configurations, e.g.:
$ ./x86_64-softmmu/qemu-system-x86_64 \
-smp 1,dies=2,maxcpus=2 \
-cpu EPYC,check=off,enforce=off \
-machine accel=kvm
qemu-system-x86_64: kvm_init_vcpu failed: Argument list too long
This happens because QEMU adds a lot of all-zeroes CPUID entries
for unused CPUID leaves. In the example above, we end up
creating 48 all-zeroes CPUID entries.
KVM already returns all-zeroes when emulating the CPUID
instruction if an entry is missing, so the all-zeroes entries are
redundant. Skip those entries. This reduces the CPUID table
size by half while keeping CPUID output unchanged.

Drop the duplicated definition of cpuid AVX512_VBMI macro and rename
it as CPUID_7_0_ECX_AVX512_VBMI. Rename CPUID_7_0_ECX_VBMI2 as
CPUID_7_0_ECX_AVX512_VBMI2.

Add some comments, clean up comments over 80 chars per line. And there

The memory-device list built by memory_device_build_list is ordered by
its address, this means if the tmp range exceed the hinted range, all
the following range will not overlap with it.
And this won't change default pc-dimm mapping and address assignment stay
the same as before this change.
