Core:
- Move the interrupt affinity spreading mechanism into lib/group_cpus
so it can be used for similar spreading requirements, e.g. in the
block multi-queue code.
This also contains a first usecase in the block multi-queue code which
Jens asked to take along with the librarization.
- Improve irqdomain locking to close a number race conditions which
can be observed with massive parallel device driver probing.
- Enforce and document the semantics of disable_irq() which cannot be
invoked safely from non-sleepable context.
- Move the IPI multiplexing code from the Apple AIC driver into the
core. so it can be reused by RISCV.
Drivers:
- Plug OF node refcounting leaks in various drivers.
- Correctly mark level triggered interrupts in the Broadcom L2 drivers.
- The usual small fixes and improvements.
- No new drivers for the record!
