Linus Torvalds 4c551165e7 Updates for the interrupt subsystem:
- Consolidation of the machine_kexec_mask_interrupts() by providing a
     generic implementation and replacing the copy & pasta orgy in the
     relevant architectures.
 
   - Prevent unconditional operations on interrupt chips during kexec
     shutdown, which can trigger warnings in certain cases when the
     underlying interrupt has been shut down before.
 
   - Make the enforcement of interrupt handling in interrupt context
     unconditionally available, so that it actually works for non x86
     related interrupt chips. The earlier enablement for ARM GIC chips set
     the required chip flag, but did not notice that the check was hidden
     behind a config switch which is not selected by ARM[64].
 
   - Decrapify the handling of deferred interrupt affinity setting. Some
     interrupt chips require that affinity changes are made from the context
     of handling an interrupt to avoid certain race conditions. For x86 this
     was the default, but with interrupt remapping this requirement was
     lifted and a flag was introduced which tells the core code that
     affinity changes can be done in any context. Unrestricted affinity
     changes are the default for the majority of interrupt chips. RISCV has
     the requirement to add the deferred mode to one of it's interrupt
     controllers, but with the original implementation this would require to
     add the any context flag to all other RISC-V interrupt chips. That's
     backwards, so reverse the logic and require that chips, which need the
     deferred mode have to be marked accordingly. That avoids chasing the
     'sane' chips and marking them.
 
   - Add multi-node support to the Loongarch AVEC interrupt controller
     driver.
 
   - The usual tiny cleanups, fixes and improvements all over the place.

Pull interrupt subsystem updates from Thomas Gleixner:

 - Consolidate the machine_kexec_mask_interrupts() by providing a
   generic implementation and replacing the copy & pasta orgy in the
   relevant architectures.

 - Prevent unconditional operations on interrupt chips during kexec
   shutdown, which can trigger warnings in certain cases when the
   underlying interrupt has been shut down before.

 - Make the enforcement of interrupt handling in interrupt context
   unconditionally available, so that it actually works for non x86
   related interrupt chips. The earlier enablement for ARM GIC chips set
   the required chip flag, but did not notice that the check was hidden
   behind a config switch which is not selected by ARM[64].

   Some interrupt chips require that affinity changes are made from the
   context of handling an interrupt to avoid certain race conditions.
   For x86 this was the default, but with interrupt remapping this
   requirement was lifted and a flag was introduced which tells the core
   code that affinity changes can be done in any context. Unrestricted
   affinity changes are the default for the majority of interrupt chips.
