Linus Torvalds 5a47ebe98e Updates for the interrupt subsystem:
Core changes:
 
   - Prevent a potential deadlock when initial priority is assigned to a
     newly created interrupt thread. A recent change to plug a race between
     cpuset and __sched_setscheduler() introduced a new lock dependency
     which is now triggered. Break the lock dependency chain by moving the
     priority assignment to the thread function.
 
   - A couple of small updates to make the irq core RT safe.
 
   - Confine the irq_cpu_online/offline() API to the only left unfixable
     user Cavium Octeon so that it does not grow new usage.
 
   - A small documentation update
 
  Driver changes:
 
   - A large cross architecture rework to move irq_enter/exit() into the
     architecture code to make addressing the NOHZ_FULL/RCU issues simpler.
 
   - The obligatory new irq chip driver for Microchip EIC
 
   - Modularize a few irq chip drivers
 
   - Expand usage of devm_*() helpers throughout the driver code
 
   - The usual small fixes and improvements all over the place
