The Debian and GNU architecture names match very often, even though
there are common cases (32-bit Arm or 64-bit x86) where they do not
and other cases in which the GNU triplet is actually a quadruplet.
But it is still possible to group the common case into a single
case inside probe_target_compiler.

Keep together all the conditions that lead to disabling plugins, and

Since the option was not in SKIP_OPTIONS, it was present twice in

Remove the duplication and take the occasion to document the option as
autodetected, which it is.

xen_ss is added unconditionally to arm_ss and i386_ss (the only
targets that can have CONFIG_XEN enabled) and its contents are gated by
CONFIG_XEN; xen_specific_ss has no condition for its constituent files
but is gated on CONFIG_XEN when its added to specific_ss.
So xen_ss is a duplicate of xen_specific_ss, though defined in a
different way. Merge the two by eliminating xen_ss.

Say QEMU is configured with bindir = "/usr/bin" and a firmware path
that starts with "/usr/share/qemu". Ever since QEMU 5.2, QEMU's
install has been relocatable: if you move qemu-system-x86_64 from
/usr/bin to /home/username/bin, it will start looking for firmware in
/home/username/share/qemu. Previously, you would get a non-relocatable
install where the moved QEMU will keep looking for firmware in
/usr/share/qemu.
Windows almost always wants relocatable installs, and in fact that
is why QEMU 5.2 introduced relocatability in the first place.
However, newfangled distribution mechanisms such as AppImage
(https://docs.appimage.org/reference/best-practices.html), and
possibly NixOS, also dislike using at runtime the absolute paths
that were established at build time.
On POSIX systems you almost never care; if you do, your usecase
dictates which one is desirable, so there's no single answer.
Obviously relocatability works fine most of the time, because not many
people have complained about QEMU's switch to relocatable install,
and that's why until now there was no way to disable relocatability.
But a non-relocatable, non-modular binary can help if you want to do
experiments with old firmware and new QEMU or vice versa (because you
can just upgrade/downgrade the firmware package, and use rpm2cpio or
similar to extract the QEMU binaries outside /usr), so allow both.
This patch allows one to build a non-relocatable install using a new
option to configure. Why? Because it's not too hard, and because
it helps the user double check the relocatability of their install.
Note that the same code that handles relocation also lets you run QEMU
from the build tree and pick e.g. firmware files from the source tree
transparently. Therefore that part remains active with this patch,
even if you configure with --disable-relocatable.

Meson tries to run scripts via the shebang line if they files are
marked as executable. If "python3" is not in the $PATH, or if it
is a version that is too old, then the script execution fails.
We should make sure to run scripts via the python3 interpreter
that is used for Meson itself. For this, the files need to be marked
as non-executable, then meson will use the python3 binary that has
been used to run itself.

Merge tag 'mem-2023-10-12' of https://github.com/davidhildenbrand/qemu into staging
Hi,
"Host Memory Backends" and "Memory devices" queue ("mem"):
- Support memory devices with multiple memslots
- Support memory devices that dynamically consume memslots
- Support memory devices that can automatically decide on the number of
memslots to use
- virtio-mem support for exposing memory dynamically via multiple
memslots
- Some required cleanups/refactorings

Fixed four ufs-related coverity issues.
The coverity issues and fixes are as follows
1. CID 1519042: Security issue with the rand() function
Changed to use a fixed value (0xab) instead of rand() as
the value for testing
2. CID 1519043: Dereference after null check
Removed useless (redundant) null checks
3. CID 1519050: Out-of-bounds access issue
Fix to pass an array type variable to find_first_bit and
find_next_bit using DECLARE_BITMAP()
4. CID 1519051: Out-of-bounds read issue
Fix incorrect range check for lun
Fix coverity CID: 1519042 1519043 1519050 1519051

The system test shutdown uses the 'loongarch_virt_pm' region.
We can use the write AcpiFadtData.sleep_clt register to realize the shutdown.

The LoongArch 'virt' machine doesn't use its ISA I/O region.
If a ISA device were to be mapped there, there is no support
for ISA IRQ. Unlikely useful. Simply remove.

In many cases we just want an effect of qmp command and want to raise
on failure. Use vm.cmd() method which does exactly this.
The commit is generated by command
git grep -l '\.qmp(' | xargs ./scripts/python_qmp_updater.py
And then, fix self.assertRaises to expect ExecuteError exception in
tests/qemu-iotests/124
