All right, now we're talking! Could you test and review this patch:
https://lore.kernel.org/linux-arm-kernel/20260910-arm-generic-irq-entry-v7-1-v3-1-5fd90f6859e1@xxxxxxxxxx/

I do avoid touching the v7m path and it worked last time I tested
it  (on an STM32) but I'd like to see your take on it, AFAICT generic
entry is not really possible (easily) on v7m because of the
pendable service call mechanism but maybe we can think of a
really complicated solution? ;)

Yours,
