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

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.

block: Add option to use driver whitelist even in tools
Currently, the block driver whitelists are only applied for the system
emulator. All other binaries still give unrestricted access to all block
drivers. There are use cases where this made sense because the main
concern was avoiding customers running VMs on less optimised block
drivers and getting bad performance. Allowing the same image format e.g.
as a target for 'qemu-img convert' is not a problem then.
However, if the concern is the supportability of the driver in general,
either in full or when used read-write, not applying the list driver
whitelist in tools doesn't help - especially since qemu-nbd and
qemu-storage-daemon now give access to more or less the same operations
in block drivers as running a system emulator.
In order to address this, introduce a new configure option that enforces
the driver whitelist in all binaries.

QEMU currently crashes when the user tries to do something like:

This happens because net_tx_pkt_init() is called with max_frags == 0 and
thus the allocation
p->raw = g_new(struct iovec, max_frags);
results in a NULL pointer that causes the
assert(pkt->raw);
in net_tx_pkt_reset() to fail later. To fix this issue we can check
that max_raw_frags was not zero before asserting that pkt->raw is
a non-NULL pointer.

configure: Fix endianess test with LTO
If a user is trying to compile QEMU with link-time optimization

then the endianess test is failing since the magic values do not
show up in the intermediate object files there. If the host is
a big endian machine (like s390x), the QEMU binary is then unusable
since the corresponding variable "bigendian" is pre-initialized
with "no".
To fix this issue, we should rather create a full binary and look
for the magic strings there instead.
And we really should not continue the build if the endianess check
failed, to make it clear right from the start that something went
wrong here, thus let's also add some "exit 1" statements here
after emitting the error message.

hw/acpi/ich9: Set ACPI PCI hot-plug as default on Q35
Q35 has three different types of PCI devices hot-plug: PCIe Native,
SHPC Native and ACPI hot-plug. This patch changes the default choice
for cold-plugged bridges from PCIe Native to ACPI Hot-plug with
ability to use SHPC and PCIe Native for hot-plugged bridges.
This is a list of the PCIe Native hot-plug issues that led to this
change:
* no racy behavior during boot (see 110c477c2ed)
* no delay during deleting - after the actual power off software
must wait at least 1 second before indicating about it. This case
is quite important for users, it even has its own bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1594168
* no timer-based behavior - in addition to the previous example,
the attention button has a 5-second waiting period, during which
the operation can be canceled with a second press. While this
looks fine for manual button control, automation will result in
the need to queue or drop events, and the software receiving
events in all sort of unspecified combinations of attention/power
indicator states, which is racy and uppredictable.
* fixes:
* https://bugzilla.redhat.com/show_bug.cgi?id=1752465
* https://bugzilla.redhat.com/show_bug.cgi?id=1690256
To return to PCIe Native hot-plug:
-global ICH9-LPC.acpi-pci-hotplug-with-bridge-support=off
Known issue: older linux guests need the following flag
to allow hotplugged pci express devices to use io:
-device pcie-root-port,io-reserve=4096.
io is unusual for pci express so this seems minor.
We'll fix this by a follow up patch.

Currently the firmware dynamic info (fw_dyn) is put right after

fw_dynamic uses ld to read contents from 'struct fw_dynamic_info',
which expects fw_dyn to be on the 8-byte boundary, otherwise the
misaligned load exception may happen. Fortunately this does not
cause any issue on QEMU, as QEMU does support misaligned load.
RV32 does not have any issue as it is 4-byte aligned already.

This adds a new section in the documentation to demonstrate how to
use the new direct kernel boot feature for Microchip Icicle Kit,

as an example.
It also updates the truth table to have a new '-dtb' column which is

Introduce the X86_FW_OVMF Kconfig symbol for OVMF-specific code.
Move the OVMF-specific code from pc_sysfw.c to pc_sysfw_ovmf.c,
adding a pair of stubs.
Update MAINTAINERS to reach OVMF maintainers when these new
files are modified.
This fixes when building the microvm machine standalone:

Add assertion in pc_system_ovmf_table_find that verifies that the flash
was indeed previously parsed (looking for the OVMF table) by
pc_system_parse_ovmf_flash.
Now pc_system_ovmf_table_find distinguishes between "no one called
pc_system_parse_ovmf_flash" (which will abort due to assertion failure)
and "the flash was parsed but no OVMF table was found, or it is invalid"
(which will return false).

gitlab-ci: Extract EDK2 job rules to reusable section
All jobs depending on 'docker-edk2' job must use at most all
the rules that triggers it. The simplest way to ensure that
is to always use the same rules. Extract all the rules to a
reusable section, and include this section (with the 'extends'
keyword) in both 'docker-edk2' and 'build-edk2' jobs.
The problem was introduced in commit 71920809cea ("gitlab-ci.yml:
Add jobs to build EDK2 firmware binaries"), but was revealed in
commit 1925468ddbf ("docker: EDK2 build job depends on EDK2
container") and eventually failed on CI:

vfio: Fix CID 1458134 in vfio_register_ram_discard_listener()
CID 1458134: Integer handling issues (BAD_SHIFT)
In expression "1 << ctz64(container->pgsizes)", left shifting by more
than 31 bits has undefined behavior. The shift amount,
"ctz64(container->pgsizes)", is 64.
Commit 5e3b981c330c ("vfio: Support for RamDiscardManager in the !vIOMMU
case") added an assertion that our granularity is at least as big as the
page size.
Although unlikely, we could have a page size that does not fit into
32 bit. In that case, we'd try shifting by more than 31 bit.
Let's use 1ULL instead and make sure we're not shifting by more than 63
bit by asserting that any bit in container->pgsizes is set.

tcg/plugins: enable by default for most TCG builds
Aside from a minor bloat to file size the ability to have TCG plugins
has no real impact on performance unless a plugin is actively loaded.
Even then the libempty.so plugin shows only a minor degradation in
performance caused by the extra book keeping the TCG has to do to keep
track of instructions. As it's a useful feature lets just enable it by
default and reduce our testing matrix a little.
We need to move our linker testing earlier so we can be sure we can
enable the loader module required. As we have ruled out static &
plugins in an earlier patch we can also reduce the indent a little.
