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
