When running "qemu-system-x86_64 -M pc,help" I noticed that some
properties were still missing their description. Add them now so
that users get at least a slightly better idea what they are all
about.

cherry picked from b259772afc29ef6af4e911d8e695dd7e2ed31066
vhost_dev_init calls vhost_dev_cleanup in case of an error during
initialization, which zeroes out the entire vsc->dev as well as the
vsc->dev.vqs pointer. This prevents us from properly freeing it in free_vqs.
Keep a local copy of the pointer so we can free it later.

Subject: [PATCH] i386/sev: Avoid SEV-ES crash due to missing MSR_EFER_LMA
bit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Commit 7191f24c7fcf ("accel/kvm/kvm-all: Handle register access errors")
added error checking for KVM_SET_SREGS/KVM_SET_SREGS2. In doing so, it
exposed a long-running bug in current KVM support for SEV-ES where the
kernel assumes that MSR_EFER_LMA will be set explicitly by the guest
kernel, in which case EFER write traps would result in KVM eventually
seeing MSR_EFER_LMA get set and recording it in such a way that it would
be subsequently visible when accessing it via KVM_GET_SREGS/etc.
However, guest kernels currently rely on MSR_EFER_LMA getting set
automatically when MSR_EFER_LME is set and paging is enabled via
CR0_PG_MASK. As a result, the EFER write traps don't actually expose the
MSR_EFER_LMA bit, even though it is set internally, and when QEMU
subsequently tries to pass this EFER value back to KVM via
KVM_SET_SREGS* it will fail various sanity checks and return -EINVAL,
which is now considered fatal due to the aforementioned QEMU commit.
This can be addressed by inferring the MSR_EFER_LMA bit being set when
paging is enabled and MSR_EFER_LME is set, and synthesizing it to ensure
the expected bits are all present in subsequent handling on the host
side.
Ultimately, this handling will be implemented in the host kernel, but to
avoid breaking QEMU's SEV-ES support when using older host kernels, the
same handling can be done in QEMU just after fetching the register
values via KVM_GET_SREGS*. Implement that here.

Subject: [PATCH] iotests: fix default machine type detection
The machine type is being detected based on "-M help" output, and we're
searching for the line ending with " (default)". However, in downstream
one of the machine types s marked as deprecated might become the
default, in which case this logic breaks as the line would now end with
" (default) (deprecated)". To fix potential issues here, let's relax
that requirement and detect the mere presence of " (default)" line
instead.

Subject: [PATCH] migration: Set downtime_start even for postcopy
cheery-pick from 62f5da7dd10a594fb30cebb5569dc738456f7131
Postcopy calculates its downtime separately. It always sets
MigrationState.downtime properly, but not MigrationState.downtime_start.
Make postcopy do the same as other modes on properly recording the
timestamp when the VM is going to be stopped. Drop the temporary variable
in postcopy_start() along the way.

Subject: [PATCH] revert "tcg/loongarch64: Fix tcg_out_mov() Aborted"
openEuler loongarch64 does not support qemu tcg,
so no TCG-related patch is required for synchronization.

Subject: [PATCH] s390x: Fix spelling errors
mainline inclusion
commit 44ee69ea16bd0390082ed88d4e82d6cea3a18b46
category: bugfix
---------------------------------------------------------------
Fix typos (discovered with the 'codespell' utility).
Note: Though "migrateable" still seems to be a valid spelling, we change
it to "migratable" since this is the way more common spelling here.

I missed this when going through the recent failure logs. I can run
the test 30 times without failure locally but it seems to hang pretty
reliably on GitLab's CI infra-structure.

Commit d921fea338 ("ui/vnc-clipboard: fix infinite loop in
inflate_buffer (CVE-2023-3255)") removed this hunk, but it is still
required, because it can happen that stream.avail_in becomes zero
before coming across a return value of Z_STREAM_END in the loop.
This fixes the host->guest direction of the clipboard with noVNC and
TigerVNC as clients.

When vdpa device not started, we don't need to suspend vdpa device
and send vdpa device state information. Therefore, add the suspended
flag of vdpa device to distinguish whether the device is suspended and
use it to determine whether the device needs to resume in dest qemu.

Subject: [PATCH] vdpa: set vring enable only if the vring address has already
been set
Currently, vhost-vdpa does not determine the status of each vring when
performing the enable operation on vring. When the vBIOS(EDK2) is running,
the driver will not enable all vrings. In this case, setting all vrings
to enable is isconsistent with the actual situation.
Add logic when enabling vring, make a judement on the vring status. If the
vring address is not set, the vring will not enabled.

Subject: [PATCH] virtio/vhost-vsock: don't double close vhostfd, remove
redundant cleanup
cherry picked from d731ab31196579144457c7f2fa3649338bfb21f2
In case of an error during initialization in vhost_dev_init, vhostfd is
closed in vhost_dev_cleanup. Remove close from err_virtio as it's both
redundant and causes a double close on vhostfd.
