Dear RT folks!

I'm pleased to announce the v5.12-rc3-rt3 patch set.

My little rpi4b is fairly unhappy with 5.12-rt, whereas 5.11-rt works
fine on it.  The below spew is endless, making boot endless.  I turned
it into a WARN_ON_ONCE to see if the thing would finish boot, and
surprisingly, it seems perfectly fine with that bad idea. Having not
the foggiest clue what I'm doing down in arm arch-land, bug is in no
immediate danger :)

Yeah, I've had the same issue with my Marvell
ESPRESSObin. WARN_ON_ONCE() made it boot and it runs without any
problems since then. Thanks!

Thanks,
Kurt
