168d46749d m48t59-test: avoid possible overflow on ABS
Originally meant to avoid a shadowed variable "s", which was fixed by
renaming the outer declaration to "qts".  Avoid the chance of an overflow
in the computation of ABS(t - s).

ea985d235b pc_piix: remove pc-i440fx-1.4 up to pc-i440fx-1.7
These are the last users of the 128K SeaBIOS blob in the i440FX family.
Removing them allows us to drop PCI support from the 128K blob,
thus making it easier to update SeaBIOS to newer versions.

0189c279af iotests: use TEST_IMG_FILE instead of TEST_IMG in _require_large_file
We need to check that we are able to create large enough file which is
used as an export base rather than connection URL. Unfortunately, there
are cases when the TEST_IMG_FILE is not defined. We should fallback to
TEST_IMG in that case.

This problem has been detected when running
    ./check -nbd 5
The test should be able to run while it does not.

5f7b71fb99 target/arm: Update user-mode ID reg mask values
For user-only mode we reveal a subset of the AArch64 ID registers
to the guest, to emulate the kernel's trap-and-emulate-ID-regs
handling. Update the feature bit masks to match upstream kernel
commit a48fa7efaf1161c1c.

None of these features are yet implemented by QEMU, so this
doesn't yet have a behavioural change, but implementation of
FEAT_MOPS and FEAT_HBC is imminent.

e6d3486d9a tests: fix broken deduplication check in parallels format test
Original check is broken as supposed reading from 2 different clusters
results in read from the same file offset twice. This is definitely
wrong.

We should be sure that
* the content of both clusters is correct after repair
* clusters are at the different offsets after repair
In order to check the latter we write some content into the first one
and validate that fact.

    parallels: Image repairing in parallels_open()
there is a potential pit fall with calling
    qemu-io -c "read"
The image is opened in read-write mode and thus could be potentially
repaired. This could ruin testing process.

The patch forces read-only opening for reads. In that case repairing
is impossible.

c8bf923d5e test-bdrv-drain: avoid race with BH in IOThread drain test
This patch fixes a race condition in test-bdrv-drain that is difficult
to reproduce. test-bdrv-drain sometimes fails without an error message
on the block pull request sent by Kevin Wolf on Sep 4, 2023. I was able
to reproduce it locally and found that "block-backend: process I/O in
the current AioContext" (in this patch series) is the first commit where
it reproduces.

I do not know why "block-backend: process I/O in the current AioContext"
exposes this bug. It might be related to the fact that the test's preadv
request runs in the main thread instead of IOThread a after my commit.
That might simply change the timing of the test.

Now on to the race condition in test-bdrv-drain. The main thread
schedules a BH in IOThread a and then drains the BDS:

  aio_bh_schedule_oneshot(ctx_a, test_iothread_main_thread_bh, &data);

  /* The request is running on the IOThread a. Draining its block device
   * will make sure that it has completed as far as the BDS is concerned,
   * but the drain in this thread can continue immediately after
   * bdrv_dec_in_flight() and aio_ret might be assigned only slightly
   * later. */
  do_drain_begin(drain_type, bs);

If the BH completes before do_drain_begin() then there is nothing to
worry about.

If the BH invokes bdrv_flush() before do_drain_begin(), then
do_drain_begin() waits for it to complete.

The problematic case is when do_drain_begin() runs before the BH enters
bdrv_flush(). Then do_drain_begin() misses the BH and the drain
mechanism has failed in quiescing I/O.

Fix this by incrementing the in_flight counter so that do_drain_begin()
waits for test_iothread_main_thread_bh().

52b10c9c0c qemu-img: map: report compressed data blocks
Right now "qemu-img map" reports compressed blocks as containing data
but having no host offset.  This is not very informative.  Instead,
let's add another boolean field named "compressed" in case JSON output
mode is specified.  This is achieved by utilizing new allocation status
flag BDRV_BLOCK_COMPRESSED for bdrv_block_status().

Also update the expected qemu-iotests outputs to contain the new field.

Instead of taking the writer lock internally, require callers to already

already hold the graph lock once the locking work is completed, which
