effe47ff48 target/arm: Drop ARM_FEATURE_IWMMXT handling
We have now removed all the CPU types which had the Intel XScale
extensions indicated via ARM_FEATURE_IWMMXT, so this feature bit
is never set. Remove all the code that can only be reached when
using this flag.

cdafe5bd90 target/arm: Remove XScale and iWMMXt translate.c code
Remove all the translator code that is accessible only via
ARM_FEATURE_XSCALE or ARM_FEATURE_IWMMXT.  This includes the
xscale-only cp15_cpar TB flags and cpu_{V0,V1,M0} TCG temps.

The no-longer-used helper functions will be removed in a separate
commit.

5b3764d9e3 target/arm: Remove deprecated pxa CPU family
In 10.0 we deprecated the pxa CPU family (pxa250, pxa255, pxa260
pxa261, pxa262, pxa270-a0, pxa270-a1, pxa270, pxa270-b0, pxa270-b1,
pxa270-c0, pxa270-c5).  Now we have released 10.1 we can remove them.

This commit removes only the top level CPU definitions and updates
the documentation. Removing the CPUs means that there is now a lot
of dead iwMMXt code, which we will delete in subsequent commits.

cc2c5027dc hw/arm/raspi4b: remove redundant check in raspi_add_memory_node
The if (acells == 0 || scells == 0) check is redundant in
raspi_add_memory_node, since it is already checked in the call
chain, arm_load_dtb. Also the return value of the function is
not checked/used so it's removed.

exception codes: uncategorized (do_el0_undef),
systemregistertrap (do_el0_sys), smetrap (do_sme_acc),
btitrap (do_el0_bti) and illegalstate (bad_el0_sync).
Only pacfail uses ILL_ILLOPN (do_el0_fpac).

Note that EC_MOP (do_el0_mops) ought not signal at all.
For now, preserve existing behavior signalling ILL_ILLOPN.

List all other exception codes and document why they do
not apply to user-only.

424dc390ec tests, scripts: Don't import print_function from __future__
Some of our Python scripts still include the line
  from __future__ import print_function

which is intended to allow a Python 2 to handle the Python 3 print()
syntax. This particular part of the future arrived many years ago,
and our minimum Python version is 3.9, so we don't need to keep
this line around.

NB: the scripts in tests/tcg/*/gdbstub/ are run with whatever Python
gdb was built against, but we can safely assume that that was a
Python 3 because our supported distros are all on Python 3.  In any
case these are only run as part of "make check-tcg", not by
end-users.

Commit created with:

 sed -i -e '/import print_function/d' $(git grep -l 'from __future__')

606978500c block/curl: fix curl internal handles handling
block/curl.c uses CURLMOPT_SOCKETFUNCTION to register a socket callback.
According to the documentation, this callback is called not just with
application-created sockets but also with internal curl sockets, - and
for such sockets, user data pointer is not set by the application, so
the result qemu crashing.

Pass BDRVCURLState directly to the callback function as user pointer,
instead of relying on CURLINFO_PRIVATE.

This problem started happening with update of libcurl from 8.9 to 8.10 --
apparently with this change curl started using private handles more.

(CURLINFO_PRIVATE is used in one more place, in curl_multi_check_completion() -
it might need a similar fix too)

Now that the isapc logic has been split out of pc_piix.c, the PCI Host Bridge
(phb) object is now always set in pc_init1().

Since phb is now guaranteed not to be NULL, Coverity reports that the if()
statement surrounding ioapic_init_gsi() is now unnecessary and can be removed
along with the phb NULL initialiser.

This happens because we declared the MemoryDeviceInfoList *md_list
with g_autofree, which will free the direct memory with g_free() but
doesn't free all the other data structures referenced by it.  Instead
what we want is to declare the pointer with g_autoptr(), which will
automatically call the qapi_free_MemoryDeviceInfoList() cleanup
function when the variable goes out of scope.

we realize the dpcd with qdev_realize() and the edid with

Instead, explicitly object_unref() after we have added the objects as
child properties of the device.  This means they will automatically
be freed when this device is deinited.  When we do this,
qdev_realize() is the correct way to realize them in
xlnx_dp_realize().

4dec497264 hw/misc/xlnx-versal-cframe-reg: Free FIFO, g_tree on deinit
In the xlnx-versal-cframe-reg device we create a FIFO in
instance_init but don't destroy it on deinit, causing ASAN
to report a leak in the device-introspect-test:

Direct leak of 400 byte(s) in 1 object(s) allocated from:

3284d1c07c hw/gpio/pca9554: Avoid leak in pca9554_set_pin()
In pca9554_set_pin() we have a string property which we parse in
order to set some non-string fields in the device state.  So we call
visit_type_str(), passing it the address of the local variable
state_str.

visit_type_str() will allocate a new copy of the string; we
never free this string, so the result is a memory leak, detected
by ASAN during a "make check" run:

Direct leak of 5 byte(s) in 1 object(s) allocated from:

Make the state_str g_autofree, so that we will always free
it, on both error-exit and success codepaths.

f905be6237 hw/ide/ich.c: Use qemu_init_irq_child() to avoid memory leak
The ICH9 PCI device uses qemu_init_irq() in its instance_init method,
but fails to clean it up in its uninit. This results in a leak,
detected by ASAN when running the device-introspect-test:

Direct leak of 96 byte(s) in 1 object(s) allocated from:

We could call qemu_free_irq() in pci_ich9_uninit(), but
since we have a method of initializing the IRQ that doesn't
need manual freeing, use that instead: qemu_init_irq_child().
