9ca5b0e842 quorum: Require WRITE perm with rewrite-corrupted
Using rewrite-corrupted means quorum may issue writes to its children
just from receiving read requests from its parents.  Thus, it must take
the WRITE permission when rewrite-corrupted is used.

ece4fa9152 file-posix: allow -EBUSY errors during write zeros on raw block devices
On Linux, fallocate(fd, FALLOC_FL_PUNCH_HOLE) when it is used on a block device,
without O_DIRECT can return -EBUSY if it races with another write to the same page.

Since this is rare and discard is not a critical operation, ignore this error

5aaabf9161 iotests: Replace deprecated ConfigParser.readfp()
iotest 277 fails on Fedora 33 (Python 3.9) because a deprecation warning
changes the output:

    nbd-fault-injector.py:230: DeprecationWarning: This method will be
    removed in future versions.  Use 'parser.read_file()' instead.

In fact, readfp() has already been deprecated in Python 3.2 and the
replacement has existed since the same version, so we can now
unconditionally switch to read_file().

6deb20f668 char-stdio: Fix QMP default for 'signal'
Commit 02c4bdf1 tried to make signal=on the default for stdio chardevs
except for '-serial mon:stdio', but it forgot about QMP and accidentally
switched the QMP default from true (except for -nographic) to false
(always). The documentation was kept unchanged and still describes the
opposite of the old behaviour (which is an even older documentation
bug).

Fix all of this by making signal=true the default in ChardevStdio and
documenting it as such.

575094b786 hw/sd: Fix 2 GiB card CSD register values
Per the SD spec, to indicate a 2 GiB card, BLOCK_LEN shall be 1024
bytes, hence the READ_BL_LEN field in the CSD register shall be 10
instead of 9.

This fixes the acceptance test error for the NetBSD 9.0 test of the
Orange Pi PC that has an expanded SD card image of 2 GiB size.

1370d61ae3 memory: Skip dirty tracking for un-migratable memory regions
It makes no sense to track dirty pages for those un-migratable memory
regions (e.g., Memory BAR region of the VFIO PCI device) and doing so
will potentially lead to some unpleasant issues during migration [1].

Skip dirty tracking for those regions by evaluating if the region is
migratable before setting dirty_log_mask (DIRTY_MEMORY_MIGRATION).

42ccce1981 target/i386: avoid theoretical leak on MCE injection
g_strdup_printf is used twice to write to the same variable, which
can theoretically cause a leak.  In practice, it is extremely
unlikely that a guest is seeing a recursive MCE and has disabled
CR4.MCE between the first and the second error, but we can fix it
and we can also make a slight improvement on the logic: CR4.MCE=0
causes a triple fault even for a non-recursive machine check, so
let's place its test first.

b430b51395 util/vfio-helpers.c: Use ram_block_discard_disable() in qemu_vfio_open_pci()
Currently, when using "nvme://" for a block device, like
    -drive file=nvme://0000:01:00.0/1,if=none,id=drive0 \
    -device virtio-blk,drive=drive0 \

VFIO may pin all guest memory, and discarding of RAM no longer works as
expected. I was able to reproduce this easily with my
    01:00.0 Non-Volatile memory controller: Samsung Electronics Co Ltd
            NVMe SSD Controller SM981/PM981/PM983

Similar to common VFIO, we have to disable it, making sure that:
a) virtio-balloon won't discard any memory ("silently disabled")
b) virtio-mem and nvme:// run mutually exclusive

2654ace151 kvm/i386: Set proper nested state format for SVM
Currently, the nested state format is hardcoded to VMX. This will result
in kvm_put_nested_state() returning an error because the KVM SVM support
checks for the nested state to be KVM_STATE_NESTED_FORMAT_SVM. As a
result, kvm_arch_put_registers() errors out early.

Update the setting of the format based on the virtualization feature:
  VMX - KVM_STATE_NESTED_FORMAT_VMX
  SVM - KVM_STATE_NESTED_FORMAT_SVM

Also, fix the code formatting while at it.

a8aa94b5f8 qga: update schema for guest-get-disks 'dependents' field
The recently-added 'guest-get-disk' command returns a list of
GuestDiskInfo entries, which in turn have a 'dependents' field which
lists devices these entries are dependent upon. Thus, 'dependencies'
is a better name for this field. Address this by renaming the field
accordingly.

Additionally, 'dependents' is specified as non-optional, even though
it's not implemented for w32. This is misleading, since it gives users
the impression that a particular disk might not have dependencies,
when in reality that information is simply not known to the guest
agent. Address this by making 'dependents' an optional field, and only
marking it as in-use when the facilities to obtain this information are
available to the guest agent.

7025111a19 .gitlab-ci.d/check-patch: tweak output for CI logs
We don't need running commentary for the CI logs and by keeping it
short we might just see the problem on the first page. While we are at
it flush the previous line so order is maintained between script and
sub process.

  This architecture does not have kernel memory protection.

This is a regression. Until someone figure out the problem,
disable the test to keep CI pipeline useful.

811c74fb65 hw/i386/acpi-build: Fix maybe-uninitialized error when ACPI hotplug off
GCC 9.3.0 thinks that 'method' can be left uninitialized. This code
is already in the "if (bsel || pcihp_bridge_en)" block statement,
but it isn't smart enough to figure it out.

Restrict the code to be used only in the "if (bsel || pcihp_bridge_en)"
block statement to fix (on Ubuntu):

  ../hw/i386/acpi-build.c: In function 'build_append_pci_bus_devices':
  ../hw/i386/acpi-build.c:496:9: error: 'method' may be used uninitialized
  in this function [-Werror=maybe-uninitialized]
    496 |         aml_append(parent_scope, method);
        |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  cc1: all warnings being treated as errors

0c3e41d408 meson.build: fix building of Xen support for aarch64
Xen is supported on ARM although weirdly using the i386-softmmu model.
Checking based on the host CPU meant we never enabled Xen support. It
would be nice to enable CONFIG_XEN for aarch64-softmmu to make it not
seem weird but that will require further build surgery.
