c4c124f331 Parallels format driver:
* regular calculation of cluster used bitmap of the image file
 * cluster allocation on the base of that bitmap (effectively allocation of
   new clusters could be done inside the image if that offset space is unused)
 * support of DISCARD and WRITE_ZEROES operations
 * image check bugfixes
 * unit tests fixes
 * unit tests covering new functionality

3a2a1f97ea target/i386: Export GDS_NO bit to guests
Gather Data Sampling (GDS) is a side-channel attack using Gather
instructions. Some Intel processors will set ARCH_CAP_GDS_NO bit in
MSR IA32_ARCH_CAPABILITIES to report that they are not vulnerable to
GDS.

Make this bit available to guests.

de5bbfc602 hw/cxl: Fix out of bound array access
According to cxl_interleave_ways_enc(), fw->num_targets is allowed to be up
to 16. This also corresponds to CXL r3.0 spec. So, the fw->target_hbs[]
array is iterated from 0 to 15. But it is statically declared of length 8.
Thus, out of bound array access may occur.

Both of these warts come from commit 0657c657eb ("hw/i386/pc: add max
combined fw size as machine configuration option", 2020-12-09); clean them

Arguably, it's also better to be consistent with the binary units (such as

cb8a8b2ca9 Block-TLB support and linux-user fixes for hppa target
All 32-bit hppa CPUs allow a fixed number of TLB entries to have a
 different page size than the default 4k.
 Those are called "Block-TLBs" and are created at startup by the
 operating system and managed by the firmware of hppa machines
 through the firmware PDC_BLOCK_TLB call.
 
 This patchset adds the necessary glue to SeaBIOS-hppa and
 qemu to allow up to 16 BTLB entries in the emulation.
 
 Two patches from Mikulas Patocka fix signal delivery issues
 in linux-user on hppa.

Block-TLB support and linux-user fixes for hppa target

All 32-bit hppa CPUs allow a fixed number of TLB entries to have a
different page size than the default 4k.
Those are called "Block-TLBs" and are created at startup by the
operating system and managed by the firmware of hppa machines
through the firmware PDC_BLOCK_TLB call.

This patchset adds the necessary glue to SeaBIOS-hppa and
qemu to allow up to 16 BTLB entries in the emulation.

Two patches from Mikulas Patocka fix signal delivery issues
in linux-user on hppa.

c428b39259 block: mark aio_poll as non-coroutine
It is forbidden to block on the event loop during a coroutine, as that
can cause deadlocks due to recursive locking.

0f86afde66 block-backend: process zoned requests in the current AioContext
Process zoned requests in the current thread's AioContext instead of in
the BlockBackend's AioContext.

There is no need to use the BlockBackend's AioContext thanks to CoMutex
bs->wps->colock, which protects zone metadata.

46eb6e861b block-backend: process I/O in the current AioContext
Switch blk_aio_*() APIs over to multi-queue by using
qemu_get_current_aio_context() instead of blk_get_aio_context(). This
change will allow devices to process I/O in multiple IOThreads in the
future.

I audited existing blk_aio_*() callers:
- migration/block.c: blk_mig_lock() protects the data accessed by the
  completion callback.
- The remaining emulated devices and exports run with
  qemu_get_aio_context() == blk_get_aio_context().

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().

652b0dd808 block: remove AIOCBInfo->get_aio_context()
The synchronous bdrv_aio_cancel() function needs the acb's AioContext so
it can call aio_poll() to wait for cancellation.

It turns out that all users run under the BQL in the main AioContext, so
this callback is not needed.

Remove the callback, mark bdrv_aio_cancel() GLOBAL_STATE_CODE just like
its blk_aio_cancel() caller, and poll the main loop AioContext.

The purpose of this cleanup is to identify bdrv_aio_cancel() as an API
that does not work with the multi-queue block layer.

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.
