 - Core:

   - Add tracepoints for tasklet callbacks which makes it possible to
     analyze individual tasklet functions instead of guess working
     from the overall duration of tasklet processing

   - Ensure that secondary interrupt threads have their affinity adjusted
     correctly.

 - Drivers:

   - A large rework of the RISC-V IPI management to prepare for a new
     RISC-V interrupt architecture

   - Small fixes and enhancements all over the place

   - Removal of support for various obsolete hardware platforms and the
     related code
