In cases where a device tries to read more bytes than the block device
contains, the error is vague: "device requires X bytes, block backend
provides Y bytes".
This patch changes the errors of this function to include the block

vfio/pci: Clear MSI-X IRQ index always
When doing device assignment of a physical device, MSI-X can be
enabled with no vectors enabled and this sets the IRQ index to
VFIO_PCI_MSIX_IRQ_INDEX. However, when MSI-X is disabled, the IRQ
index is left untouched if no vectors are in use. Then, when INTx
is enabled, the IRQ index value is considered incompatible (set to
MSI-X) and VFIO_DEVICE_SET_IRQS fails. QEMU complains with :

migration: Fix use-after-free of migration state object
We're currently allowing the process_incoming_migration_bh bottom-half
to run without holding a reference to the 'current_migration' object,
which leads to a segmentation fault if the BH is still live after
migration_shutdown() has dropped the last reference to
current_migration.
In my system the bug manifests as migrate_multifd() returning true
when it shouldn't and multifd_load_shutdown() calling
multifd_recv_terminate_threads() which crashes due to an uninitialized
multifd_recv_state.
Fix the issue by holding a reference to the object when scheduling the
BH and dropping it before returning from the BH. The same is already
done for the cleanup_bh at migrate_fd_cleanup_schedule().
Stop using outside knowledge about the io channels when registering
yank functions. Query for features instead.
The yank method for all channels used with migration code currently is
to call the qio_channel_shutdown() function, so query for
QIO_CHANNEL_FEATURE_SHUTDOWN. We could add a separate feature in the
future for indicating whether a channel supports yanking, but that
seems overkill at the moment.

Add a CI job that builds the lastest release of QEMU and another job
that uses that version plus an already present build of the current
version and run the migration tests with the two, both as source and
destination. I.e.:
old QEMU (n-1) -> current QEMU (development tree)
current QEMU (development tree) -> old QEMU (n-1)
The purpose of this CI job is to ensure the code we're about to merge
will not cause a migration compatibility problem when migrating the
next release (which will contain that code) to/from the previous
release.
The version of migration-test used will be the one matching the older
QEMU. That way we can avoid special-casing new tests that wouldn't be
compatible with the older QEMU.
Note: for user forks, the version tags need to be pushed to gitlab
otherwise it won't be able to checkout a different version.

cpu-exec: simplify jump cache management
Unless I'm missing something egregious, the jmp cache is only every
populated with a valid entry by the same thread that reads the cache.
Therefore, the contents of any valid entry are always consistent and
there is no need for any acquire/release magic.
Indeed ->tb has to be accessed with atomics, because concurrent
invalidations would otherwise cause data races. But ->pc is only ever
accessed by one thread, and accesses to ->tb and ->pc within tb_lookup
can never race with another tb_lookup. While the TranslationBlock
(especially the flags) could be modified by a concurrent invalidation,
store-release and load-acquire operations on the cache entry would
not add any additional ordering beyond what you get from performing
the accesses within a single thread.
Because of this, there is really nothing to win in splitting the CF_PCREL
and !CF_PCREL paths. It is easier to just always use the ->pc field in
the jump cache.
I noticed this while working on splitting commit 8ed558ec0cb
("accel/tcg: Introduce TARGET_TB_PCREL", 2022-10-04) into multiple
pieces, for the sake of finding a more fine-grained bisection
result for https://gitlab.com/qemu-project/qemu/-/issues/2092.
It does not (and does not intend to) fix that issue; therefore
it may make sense to not commit it until the root cause
of issue #2092 is found.

bswap.h: Fix const_le64() macro
The const_le64() macro introduced in commit 845d80a8c7b187 turns out
to have a bug which means that on big-endian systems the compiler
complains if the argument isn't already a 64-bit type. This hasn't
caused a problem yet, because there are no in-tree uses, but it
means it's not possible for anybody to add one without it failing CI.
This example is from an attempted use of it with the argument '0',
from the s390 CI runner's gcc:

Fix this by making all the constants in the macro have the ULL
suffix. This will cause them all to be 64-bit integers, which means
the result of the logical & will also be an unsigned 64-bit type,
even if the input to the macro is a smaller type, and so the shifts
will be in range.

target/arm: Fix A64 scalar SQSHRN and SQRSHRN
In commit 1b7bc9b5c8bf374dd we changed handle_vec_simd_sqshrn() so
that instead of starting with a 0 value and depositing in each new
element from the narrowing operation, it instead started with the raw
result of the narrowing operation of the first element.
This is fine in the vector case, because the deposit operations for
the second and subsequent elements will always overwrite any higher
bits that might have been in the first element's result value in
tcg_rd. However in the scalar case we only go through this loop
once. The effect is that for a signed narrowing operation, if the
result is negative then we will now return a value where the bits
above the first element are incorrectly 1 (because the narrowfn
returns a sign-extended result, not one that is truncated to the
element size).
Fix this by using an extract operation to get exactly the correct
bits of the output of the narrowfn for element 1, instead of a
plain move.

hw/char/imx_serial: Implement receive FIFO and ageing timer
This patch implements a 32 half word FIFO as per imx serial device
specifications. If a non empty FIFO is below the trigger level, an
ageing timer will tick for a duration of 8 characters. On expiry,
AGTIM will be set triggering an interrupt. AGTIM timer resets when
there is activity in the receive FIFO.
Otherwise, RRDY is set when trigger level is exceeded. The receive
trigger level is 8 in newer kernel versions and 1 in older ones.
This change will break migration compatibility for the imx boards.

docs/system/arm/virt.rst: Add note on CPU features off by default
Add a note on CPU features that are off by default in `virt` machines.
Some CPU features will remain off even if a CPU-capable CPU (e.g.,
`-cpu max`) is selected because they require support in both the CPU
itself and in the wider system. Therefore, the user, besides selecting a
CPU that supports such features, must also turn on the feature using a
machine option.

fsl-imx6ul: Add various missing unimplemented devices
Add MMDC, OCOTP, SQPI, CAAM, and USBMISC as unimplemented devices.
This allows operating systems such as Linux to run emulations such as
mcimx6ul-evk.
Before commit 0cd4926b85 ("Refactor i.MX6UL processor code"), the affected
memory ranges were covered by the unimplemented DAP device. The commit
reduced the DAP address range from 0x100000 to 4kB, and the emulation
thus no longer covered the various unimplemented devices in the affected
address range.
Various files in hw/arm/ don't require "cpu.h" anymore.
Except virt-acpi-build.c, all of them don't require any
ARM specific knowledge anymore and can be build once as
target agnostic units. Update meson accordingly.

target/arm: Move GTimer definitions to new 'gtimer.h' header
Move Arm A-class Generic Timer definitions to the new

target/arm: Move ARM_CPU_IRQ/FIQ definitions to 'cpu-qom.h' header
The ARM_CPU_IRQ/FIQ definitions are used to index the GPIO
IRQ created calling qdev_init_gpio_in() in ARMCPU instance_init()
handler. To allow non-ARM code to raise interrupt on ARM cores,
move they to 'target/arm/cpu-qom.h' which is non-ARM specific and
can be included by any hw/ file.
File list to include the new header generated using:
$ git grep -wEl 'ARM_CPU_(\w*IRQ|FIQ)'
