[ANNOUNCE] v6.12.96-rt19

Hello RT-list!

I'm pleased to announce the 6.12.96-rt19 stable release.

This updates to the latest stable release. Since the latest stable=20
backports a
number of ARM patches that touch the RT code, this is not a straightforward
update. I tried various update strategies, and doing the rebase and=20
replacing
one patch resulted in the cleanest diff, making it the least likely to=20
introduce
regressions in this area.

The main change in the stable-rt tree is the removal of

 =20
patches/ARM__enable_irq_in_translation_section_permission_fault_handlers.pa=
tch

which is replaced by

   59e4f3b45b96a ("ARM: ensure interrupts are enabled in __do_user_fault()"=
)

The remaining changes are small context updates to the existing patches.

Last time I reported latency spikes in my test lab. Lukas Beckmann (thanks!=
)
tracked down the root cause:

ilbox.org/

All of the deadline scheduler fixes have since been merged into the=20
stable tree,
so this RT release picks them up as well.
