Linus Torvalds 9413cd7792 Two fixes for the interrupt subsystem:
- Make the handling of the firmware node consistent and do not free the
    node after the domain has been created successfully. The core code
    stores a pointer to it which can lead to a use after free or double
    free.
 
    This used to "work" because the pointer was not stored when the initial
    code was written, but at some point later it was required to store
    it. Of course nobody noticed that the existing users break that way.
 
  - Handle affinity setting on inactive interrupts correctly when
    hierarchical irq domains are enabled. When interrupts are inactive with
    the modern hierarchical irqdomain design, the interrupt chips are not
    necessarily in a state where affinity changes can be handled. The legacy
    irq chip design allowed this because interrupts are immediately fully
    initialized at allocation time. X86 has a hacky workaround for this, but
    other implementations do not. This cased malfunction on GIC-V3. Instead
    of playing whack a mole to find all affected drivers, change the core
    code to store the requested affinity setting and then establish it when
    the interrupt is allocated, which makes the X86 hack go away.
