0e60fc8093 vnc: fix crash when no console attached
Since commit e99441a379 ("ui/curses: Do not use console_select()")
qemu_text_console_put_keysym() no longer checks for NULL console
argument, which leads to a later crash:

fa9ddb1caf qemu-keymap: Release local allocation references
Commit 2523baf7fb ("qemu-keymap: Make references to allocations
static") made references to allocations static to ensure LeakSanitizer
can track them. This trick unfortunately did not work with gcc version
14.0.1; that compiler is clever enough to know that the value of the
"state" variable is only referred in the current execution of the
function and to put it on the stack.

Release references to allocations and suppress the error once for all.

7bd9b0b41d hw/audio/virtio-snd: Remove unnecessary "exec/tswap.h" header
We were including the "exec/tswap.h" header to get
target_words_bigendian() declaration, but since commit a276ec8e26
("hw/audio/virtio-snd: Always use little endian audio format")
removed this method call, we don't need this header anymore.

e5a0070018 tests/tcg/s390x: Test modifying an EXECUTE target
QEMU correctly implements the tracking of EXECUTE target modifications
by storing the instruction text in env->ex_value and tb->cs_base, the
latter of which is used for lookups.

Still, EXECUTE is a tricky corner of the s390x emulation, which can
benefit from having a regression test.

Could not access KVM kernel module: No such file or directory

To:
$ ./qemu-system-x86_64 --accel kvm

87e82951c1 kvm/i386: fix return values of is_host_cpu_intel()
is_host_cpu_intel() should return TRUE if the host cpu in Intel based, otherwise
it should return FALSE. Currently, it returns zero (FALSE) when the host CPU
is INTEL and non-zero otherwise. Fix the function so that it agrees more with
the semantics. Adjust the calling logic accordingly. RAPL needs Intel host cpus.
If the host CPU is not Intel baseed, we should report error.

89d26d34ce tests/unit: remove block layer code from test-nested-aio-poll
GCC is reporting a NULL pointer dereference when compiling aio_wait_kick()
with LTO.

The issue is that test-nested-aio-poll.c does not call qemu_init_main_loop().
It doesn't _need_ to because it never calls AIO_WAIT_WHILE(), but it seems
that LTO does not do enough dead-code elimination to catch that.

Fortunately aio_wait_kick() is only used in few places, and only in block
layer or system emulation code; and this test only needs the core event loop
functionality.  It does not even need iothreads.   So remove everything that
calls aio_wait_kick(), which is nice for coverage compared to adding the call
to qemu_init_main_loop().

qemu_clock_get_main_loop_timerlist and timerlist_get_clock have been
unused since they were originally added in

Remove them.

73ceb12960 Remove the unused sh4eb target
Since the "shix" machine has been removed, the "r2d" machine is the only
machine that is still available for the sh4 and sh4eb targets. However,
the "r2d" machine apparently does not work in big endian mode, see here:

 https://lore.kernel.org/qemu-devel/87a5fwjjew.wl-ysato@users.sourceforge.jp/

So there is no working machine left in the sh4eb-softmmu target, i.e. it
is currently completely useless. Thus remove it from the configuration
now. (Note: The linux-user binary is not removed since it might still
be used to run sh4 binaries in big endian mode).

01063ba5e7 configs: Fix typo in the sh4-softmmu devices config file
This is the config file for the little endian target, so there
should not be a "eb" in here.

c60473d292 testing: bump mips64el cross to bookworm and fix package list
The mips64el cross setup is very broken for bullseye which has now
entered LTS support so is unlikely to be fixed. While we still can't
build the container with all packages for bookworm due to a single
missing dependency that will hopefully get fixed in due course. For
the sake of keeping the CI green we disable the problematic packages
via the lcitool's mappings.yml file.

b3bd7617db qapi/block-core: Drop drive-backup's "Any other error" documentation
We've always been rather lax about documenting errors.  Many "Errors"
sections are obviously not exhaustive.  Only drive-backup is explicit
about this: "Any other error returns a GenericError".

Not useful.  Drop.
