however gsi base is hard-coded in linux kernel loongarch system,
else system fails to boot.
This patch renames macro PCH_PIC_IRQ_OFFSET with VIRT_GSI_BASE,

When virt ACPI files were added, lots of duplicates were created because
we forgot that there's a no-prefix fallback: e.g. if
tests/data/acpi/virt/APIC.memhp is not there then test will use
tests/data/acpi/virt/APIC.
Drop these.
These were found with
$find tests/data/acpi/ -type f -exec sha256sum '{}' ';'|sort -d|uniq -w 64 --all-repeated=separate
(trick: -d does a dictionary sort so a no-suffix file ends up first).
Note: there are still a bunch of issues with duplicates left even after this.
First pc and q35 are often identical.
Second, sometimes files are identical but not identical to the default
fallback, e.g.
tests/data/acpi/pc/SLIT.cphp and tests/data/acpi/pc/SLIT.memhp
or
tests/data/acpi/q35/HMAT.acpihmat-noinitiator and tests/data/acpi/virt/HMAT.acpihmatvirt
Finding a way to deduplicate these is still a TODO item - softlinks
maybe?
We also need to make rebuild-expected-aml.sh smarter about not creating
these duplicates in the 1st place.
And maybe we should use softlinks instead of relying on a fallback
to make it explicit what version does each test expect?

The cel_uuid was programatically generated previously because there was
no static initializer for network order UUIDs.
Use the new network order initializer for cel_uuid. Adjust
cxl_initialize_mailbox() because it can't fail now.

In char_socket_finalize after s->listener freed, event callback function
vhost_user_blk_event will be called to handle CHR_EVENT_CLOSED.
vhost_user_blk_event is calling qio_net_listener_set_client_func_full which
is still using s->listener.
Setting s->listener = NULL after object_unref(OBJECT(s->listener)) can
solve this issue.

In vhost_svq_poll(), if vhost_svq_get_buf() fails due to a device

According to g_tree_foreach() documentation:
"The tree may not be modified while iterating over it (you can't
add/remove items)."
compare_trees()/diff_tree() fail to respect this rule.
Historically GLib2 used a slice allocator for the GTree APIs
which did not immediately release the memory back to the system
allocator. As a result QEMU's use-after-free bug was not visible.
With GLib > 2.75.3 however, GLib2 has switched to using malloc
and now a SIGSEGV can be observed while running test-vmstate.
Get rid of the node removal within the tree traversal. Also
check the trees have the same number of nodes before the actual
diff.

It's cleaner and removes the curious '+ 1' required to skip the DMA

To avoid the SPI transactions fetching instructions from the FMC CE0
flash device and speed up boot, a ROM can be created if a drive is
available.
Reverse the logic to allow a machine to boot without a drive, using a
block device instead :
-blockdev node-name=fmc0,driver=file,filename=/path/to/flash.img \
-device mx66u51235f,bus=ssi.0,drive=fmc0

The default boot address of the Aspeed SoCs is 0x0. For this reason,
the FMC flash device contents are remapped by HW on the first 256MB of
the address space. In QEMU, this is currently done in the machine init
with the setup of a region alias.
Move this code to the SoC and introduce an extra container to prepare
ground for the boot ROM region which will overlap the FMC flash
remapping.

The auto completion does not work in some cases.
Case 1.
1. (qemu) info reg
2. Press 'Tab'.
3. It does not auto complete.
Case 2.
1. (qemu) block_resize flo
2. Press 'Tab'.
3. It does not auto complete 'floppy0'.
Since the readline_add_completion_of() may add any completion when
strlen(pfx) is zero, we remove the check with (name[0] == '\0') because
strlen() always returns zero in that case.

bsd-user: Helper routines h2g_old_sysctl
bsd-user: various helper routines for sysctl
]
This group of patches gets the basic framework for sysctl upstreamed. There's a
lot more to translate far too many binary blobs the kernel publishes via
sysctls, but I'm leaving those out in the name of simplicity.
There's also a bug fix from Doug Rabson that fixes a long int confusion leading
to a trunctation of addresses (oops)
There's a fix for the -static option, since clang hates -no-pie and needs only
-fno-pie.
Finally, I'm changing how I'm upstreaming a little. I'm doing a little deeper
dives into our rather chaotic repo to find a couple of authors I might have
missed. From here on out, I'll be using the original author's name as the git
author. I'll also tag the co-authors better as well when there's multiple people
that did something (other than reformat and/or move code around). I've
discovered more code moved about than I'd previously known. This seems more in
line with standard practice.
v3->pull:
o minor tweaks in the conditional reviews around formatting
o fix all errors for check patch and am OK with remaining warnings for
line length that's only slightly too long
o edited letter for changes in review process
v3:
o Removed -strict, it's not ready and needs a complete rethink.
o Add g_assert_not_reached()
o target -> guest in most places
o Use MIN() to simplify things
o Better types in many places (abi_int instead of int32_t)
o Use ARRAY_COUNT
o fix tabs copied from FreeBSD sources to spaces
v2:
o Created various helper functions to make the code a little better
o split a few patches that I thought would be approved together but
that generated commentary. It's easier to manage 1 per patch for
those.
o Add/delete G_GNU_UNUSED to ensure all patches compile w/o warnings
o Fix 64-bit running 32-bit binary to get a LONG or ULONG. Add a
bounce buffer for these so we don't overflow anything on the target
and return all the elements of arrays.
o Fixed a number of nits noticed in the review.
o Add or improve comments to explain things there were questions on
during the review.
o fix noted typos
o fix host != target page size differences
o Add pointers to FreeBSD source code, as appropriate
o fix locking (mostly unlocking) on error paths
o Note: -strict feedback not yet applied due to large numbers of changes
from the rest. Next round.
