A typo in the implementation of isar_feature_aa64_tidcp1() means we
were checking the field in the wrong ID register, so we might have
provided the feature on CPUs that don't have it and not provided
it on CPUs that should have it. Correct this bug.

The const_le64() macro introduced in commit 845d80a8c7 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:
../block/blklogwrites.c: In function ‘blk_log_writes_co_do_log’:
../include/qemu/bswap.h:148:36: error: left shift count >= width of

cc1: all warnings being treated as errors
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.

In commit 1b7bc9b5c8 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.

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.

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.

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.

Convert the musicpal key input device to use
qemu_add_kbd_event_handler(). This lets us simplify it because we no
longer need to track whether we're in the middle of a PS/2 multibyte
key sequence.
In the conversion we move the keyboard handler registration from init
to realize, because devices shouldn't disturb the state of the
simulation by doing things like registering input handlers until
they're realized, so that device objects can be introspected
safely.
The behaviour where key-repeat is permitted for the arrow-keys only
is intentional (added in commit 7c6ce4baed), so we retain it,
and add a comment to that effect.
This is a migration compatibility break for musicpal.

In arm_deliver_fault() we check for whether the fault is caused
by a data abort due to an access to a FEAT_NV2 sysreg in the
memory pointed to by the VNCR. Unfortunately part of the
condition checks the wrong argument to the function, meaning
that it would spuriously trigger, resulting in some instruction
aborts being taken to the wrong EL and reported incorrectly.
Use the right variable in the condition.

r[id]tlb[01], [iw][id]tlb opcodes use TLB way index passed in a register
by the guest. The host uses 3 bits of the index for ITLB indexing and 4
bits for DTLB, but there's only 7 entries in the ITLB array and 10 in
the DTLB array, so a malicious guest may trigger out-of-bound access to
these arrays.
Change split_tlb_entry_spec return type to bool to indicate whether TLB
way passed to it is valid. Change get_tlb_entry to return NULL in case
invalid TLB way is requested. Add assertion to xtensa_tlb_get_entry that
requested TLB way and entry indices are valid. Add checks to the
[rwi]tlb helpers that requested TLB way is valid and return 0 or do
nothing when it's not.

We're seeing timeouts for this test on CI runs (specifically for
ubuntu-20.04-s390x-all). It doesn't fail consistently, but even the
successful runs take about 27 or 28 seconds, which is not very far from
the 30 seconds timeout.
Bump the timeout a bit to make failure less likely even on this CI host.

During the review of a fix for a concurrency issue in blklogwrites,
it was found that the driver needs an additional fix when enabling
multiqueue, which is a new feature introduced in QEMU 9.0, as the
driver state may be read and written by multiple threads at the same
time, which was not the case when the driver was originally written.
Fix the multi-threaded scenario by introducing a mutex to protect the
mutable fields in the driver state, and always having the mutex locked
by the current thread when accessing them. Also use the mutex and a
CoQueue to ensure that the super block is not being written to by
multiple threads concurrently and updates are properly serialized.
Additionally, add the const qualifier to a few BDRVBlkLogWritesState
pointer targets in contexts where the driver state is not written to.

When starting ioeventfd it is common practice to set the event notifier
so that the ioeventfd handler is triggered to run immediately. There may
be no requests waiting to be processed, but the idea is that if a
request snuck in then we guarantee that it will be detected.
One scenario where self-triggering the ioeventfd is necessary is when
virtio_blk_handle_output() is called from a vCPU thread before the
VIRTIO Device Status transitions to DRIVER_OK. In that case we need to
self-trigger the ioeventfd so that the kick handled by the vCPU thread
causes the vq AioContext thread to take over handling the request(s).

A virtio-blk device with the iothread-vq-mapping parameter has
per-virtqueue AioContexts. It is not thread-safe to process s->rq
requests in the BlockBackend AioContext since that may be different from
the virtqueue's AioContext to which this request belongs. The code
currently races and could crash.
Adapt virtio_blk_dma_restart_cb() to first split s->rq into per-vq lists
and then schedule a BH each vq's AioContext as necessary. This way
requests are safely processed in their vq's AioContext.
