this way we save a bit of space and should make build also slightly
faster, otherwise nothing should change.

This allows the sbuild to start much faster (lintian takes ~ minutes
for such big packages), and that without loss as sbuild will run
lintian on both binary and source package anyway.

When turning off the "KVM hardware virtualization" checkbox in Proxmox
VE, the TCG accelerator is used, so these fixes are relevant then.
The first patch is included to allow cherry-picking the others without
changes.

Required for the debian/edk2-vars-generator.py script in the
pve-edk2-firmware repository when building the edk2-stable202302

would hang indefinietly.

The patch 0008-memory-prevent-dma-reentracy-issues.patch introduced a
regression for the LSI SCSI controller leading to boot failures [0],
because, in its current form, it relies on reentrancy for a particular
ram_io region.

The patches were selected from the recent "Patch Round-up for stable
7.2.1" [0]. Those that should be relevant for our supported use-cases
(and the upcoming nvme use-case) were picked. Most of the patches
added now have not been submitted to qemu-stable before.
The follow-up for the virtio-rng-pci migration fix will break
migration between versions with the fix and without the fix when a
virtio-pci-rng(-non)-transitional device is used. Luckily Proxmox VE
only uses the virtio-pci-rng device, and this was fixed by
0006-virtio-rng-pci-fix-migration-compat-for-vectors.patch which was
applied before any public version of Proxmox VE's QEMU 7.2 package was
released.

The patch was incomplete and (re-)introduced an issue with a potential
failing assertion upon cancelation of the DMA request.
There is a patch on qemu-devel now[0], and it's the same as this one
code-wise (except for comments). But the discussion is still ongoing.
While there shouldn't be a real issue with the patch, there might be
better approaches. The plan is to use this as a stop-gap for now and
pick up the proper solution once it's ready.

In particular, the deadlock can occur, together with unlucky timing
between the QEMU threads, when the guest is issuing trim requests
during the start of a backup operation.

[ T: resolve trivial merge conflict in series file ]

In qemu-server, we already allocate 2 * $mem_size + 500 MiB for driver
state (which was 32 MiB long ago according to git history). It seems
likely that the 30 MiB cutoff in the savevm-async implementation was
chosen based on that.
In bug #4476 [0], another issue caused the iteration to not make any
progress and the state file filled up all the way to the 30 MiB +
pending_size cutoff. Since the guest is not stopped immediately after
the check, it can still dirty some RAM and the current cutoff is not
enough for a reproducer VM (was done while bug #4476 still was not
fixed), dirtying memory with
> stress-ng -B 2 --bigheap-growth 64.0M'
After entering the final stage, savevm actually filled up the state
file completely, leading to an I/O error. It's probably the same
scenario as reported in the bug report, the error message was fixed in
commit a020815 ("savevm-async: fix function name in error message")
after the bug report.
If not for the bug, the cutoff will only be reached by a VM that's
dirtying RAM faster than can be written to the storage, so increase
the cutoff to 100 MiB to have a bigger chance to finish successfully,
while still trying to not increase downtime too much for
non-hibernation snapshots.

when pend_postcopy is large. By definition, pend_postcopy won't
decrease when iterating, so a value larger than the cutoff of 400000
would lead to essentially empty iterations, filling up the state file
until only 30 MiB + pending_size remain and the second half of the
check would trigger.
Avoid this, by not considering pend_postcopy for the cutoff to enter
the final phase.

between QEMU less than 7.2 and QEMU 7.2 without the fix (both
directions are affected).
As mentioned in the patch message, this fix itself will break
migration between QEMU 7.2 and QEMU 7.2 with the fix (in both
directions, if a virtio-rng device is attached), but this is fine,
because no pve-qemu-kvm package with QEMU 7.2 has been publicly
released yet.

Commit d03e1b3 ("update submodule and patches to 7.2.0") argued that
slirp is not explicitly supported in PVE, but that is not true. In
qemu-server, user networking is supported (via CLI/API) when no bridge
is set on a virtual NIC. So slirp needs to stay to keep such NICs
working.
