Merge tag 'pull-target-arm-20250210' of https://git.linaro.org/people/pmaydell/qemu-arm into staging

target-arm queue:
 * Deprecate pxa2xx CPUs, iwMMXt emulation, -old-param option
 * Drop unused AArch64DecodeTable typedefs
 * Minor code cleanups
 * hw/net/cadence_gem:  Fix the mask/compare/disable-mask logic
 * linux-user: Do not define struct sched_attr if libc headers do

  hw/net/cadence_gem:  Fix the mask/compare/disable-mask logic
  hw/cpu/arm: Declare CPU QOM types using DEFINE_TYPES() macro

Conflicts:
- The iwMMXt deprecation notice conflicted with the 32-bit host
  operating system deprecation notice. Add both notices.

 +Keeping 32-bit host support alive is a substantial burden for the

+ iwMMXt emulation and the ``pxa`` CPUs (since 10.0)
+ ''''''''''''''''''''''''''''''''''''''''''''''''''
+ 
+ The ``pxa`` CPU family (``pxa250``, ``pxa255``, ``pxa260``,
+ ``pxa261``, ``pxa262``, ``pxa270-a0``, ``pxa270-a1``, ``pxa270``,
+ ``pxa270-b0``, ``pxa270-b1``, ``pxa270-c0``, ``pxa270-c5``) are no
+ longer used in system emulation, because all the machine types which
+ used these CPUs were removed in the QEMU 9.2 release. These CPUs can
+ now only be used in linux-user mode, and to do that you would have to
+ explicitly select one of these CPUs with the ``-cpu`` command line
+ option or the ``QEMU_CPU`` environment variable.
+ 
+ We don't believe that anybody is using the iwMMXt emulation, and we do
+ not have any tests to validate it or any real hardware or similar
+ known-good implementation to test against. GCC is in the process of
+ dropping their support for iwMMXt codegen. These CPU types are
+ therefore deprecated in QEMU, and will be removed in a future release.
