288a5fe980 target/alpha: Drop goto_tb path in gen_call_pal
We are certain of a page crossing here, entering the
PALcode image, so the call to use_goto_tb that should
have been here will never succeed.

We are shortly going to add an assert to tcg_gen_goto_tb
that would trigger for this case.

d7ddd0a161 linux-aio: limit the batch size using aio-max-batch parameter
When there are multiple queues attached to the same AIO context,
some requests may experience high latency, since in the worst case
the AIO engine queue is only flushed when it is full (MAX_EVENTS) or
there are no more queues plugged.

Commit 2558cb8dd4 ("linux-aio: increasing MAX_EVENTS to a larger
hardcoded value") changed MAX_EVENTS from 128 to 1024, to increase
the number of in-flight requests. But this change also increased
the potential maximum batch to 1024 elements.

When there is a single queue attached to the AIO context, the issue
is mitigated from laio_io_unplug() that will flush the queue every
time is invoked since there can't be others queue plugged.

Let's use the new `aio-max-batch` IOThread parameter to mitigate
this issue, limiting the number of requests in a batch.

We also define a default value (32): this value is obtained running
some benchmarks and it represents a good tradeoff between the latency
increase while a request is queued and the cost of the io_submit(2)
system call.

1793ad0247 iothread: add aio-max-batch parameter
The `aio-max-batch` parameter will be propagated to AIO engines
and it will be used to control the maximum number of queued requests.

When there are in queue a number of requests equal to `aio-max-batch`,
the engine invokes the system call to forward the requests to the kernel.

This parameter allows us to control the maximum batch size to reduce
the latency that requests might accumulate while queued in the AIO
engine queue.

If `aio-max-batch` is equal to 0 (default value), the AIO engine will
use its default maximum batch size value.

d1751d8b5d hw/ppc/Kconfig: Add dependency PEGASOS2 -> ATI_VGA
The ATI VGA device isn't a requisite for the Pegasos2 machine
because Linux only uses the serial console; see commit ba7e5ac18e
("hw/ppc: Add emulation of Genesi/bPlan Pegasos II") for rationale.

Using the default devices we don't have any problem:

  $ qemu-system-ppc -M pegasos2
  qemu-system-ppc: standard VGA not available

But when trying to explicitly use the ATI device we get an error:

  $ qemu-system-ppc -M pegasos2 -vga none -bios pegasos2.rom -device ati-vga,romfile=
  qemu-system-ppc: -device ati-vga,romfile=: 'ati-vga' is not a valid device model name

Add it as an implicit Kconfig dependency.

461fea9bf1 qemu-config: fix memory leak on ferror()
The leak is basically impossible to reach, since the only common way
to get ferror(fp) is by passing a directory to -readconfig.  In that
case, the error occurs before qdict is set to anything non-NULL.
However, it's theoretically possible to get there after an EIO.

8573823f3b block/export: Conditionally ignore set-context error
When invoking block-export-add with some iothread and
fixed-iothread=false, and changing the node's iothread fails, the error
is supposed to be ignored.

However, it is still stored in *errp, which is wrong.  If a second error
occurs, the "*errp must be NULL" assertion in error_setv() fails:

  qemu-system-x86_64: ../util/error.c:59: error_setv: Assertion
  `*errp == NULL' failed.

So if fixed-iothread=false, we should ignore the error by passing NULL
to bdrv_try_set_aio_context().

c2cf0ecab5 replication: Remove workaround
Remove the workaround introduced in commit
6ecbc6c526
"replication: Avoid blk_make_empty() on read-only child".

It is not needed anymore since s->hidden_disk is guaranteed to be
writable when secondary_do_checkpoint() runs. Because replication_start(),
_do_checkpoint() and _stop() are only called by COLO migration code
and COLO-migration activates all disks via bdrv_invalidate_cache_all()
before it calls these functions.

3b78420bb1 replication: Properly attach children
The replication driver needs access to the children block-nodes of
it's child so it can issue bdrv_make_empty() and bdrv_co_pwritev()
to manage the replication. However, it does this by directly copying
the BdrvChilds, which is wrong.

Fix this by properly attaching the block-nodes with
bdrv_attach_child() and requesting the required permissions.

This ultimatively fixes a potential crash in replication_co_writev(),
because it may write to s->secondary_disk if it is in state
BLOCK_REPLICATION_FAILOVER_FAILED, without requesting write
permissions first. And now the workaround in
secondary_do_checkpoint() can be removed.

Commit 7abb479c7a ("PPC: E500: Add FSL I2C controller and integrate
RTC with it") added a global dependency on the DS1338 model, instead
of a machine one (via Kconfig). This gives trouble when building
standalone machines not exposing I2C bus:

  The following clauses were found for DS1338

      CONFIG_DS1338=y
      config DS1338 depends on I2C

Fix by selecting the DS1338 symbol in the single machine requiring
it, the E500.

ee9ffe0c8e hw/arm/Kconfig: Add missing SDHCI symbol to FSL_IMX25
Commit bfae1772c4 ("hw/arm/fsl-imx25: Wire up eSDHC controllers")
added a dependency on the TYPE_IMX_USDHC model, but forgot to add
the Kconfig selector. Fix that to solve when built stand-alone:

  $ qemu-system-arm -M imx25-pdk
  qemu-system-arm: missing object type 'imx-usdhc'
  Aborted (core dumped)

7795b6e152 hw/arm/Kconfig: Remove unused DS1338 symbol from i.MX25 PDK Board
In commit c4f00daa5b ("imx25-pdk: create ds1338 for qtest inside
the test") we removed the DS1338 device from the i.MX25 machine
but forgot to remove it in the machine Kconfig definitions, do
it now.

d43bb04c84 hw/arm/Kconfig: Add missing dependency NPCM7XX -> SMBUS
The TYPE_NPCM7XX_SMBUS device model exposes an SMBus, but
this isn't advertised with proper Kconfig symbol, leading
to an early build failure when building NPCM7XX machines
standalone:

  The following clauses were found for AT24C

      config AT24C depends on I2C
      select AT24C if NPCM7XX

Fix by adding SMBUS to NPCM7XX.

27d764c9c0 hw/ide/Kconfig: Add missing dependency PCI -> IDE_QDEV
The pci_ide_create_devs() function is declared i hw/ide/qdev.c:

 $ git grep ide_create_drive
 hw/ide/pci.c:491:            ide_create_drive(d->bus + bus[i], unit[i], hd_table[i]);

 include/hw/ide/internal.h:653:IDEDevice *ide_create_drive(IDEBus *bus, int unit, DriveInfo *drive);

Fix the correct symbol dependency to avoid build failure when
deselecting some machines:

  hw/ide/pci.c:491: undefined reference to `ide_create_drive'
