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 -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmF+8BUTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoWs2EACeNbL93aIFokd2/RllRSr4VvMjKNyW PpA0RYDOz1Jh4ldK+7b/EYapKgAkR3yyOtz+jyjRE7jsQK0pQeLtYNLd3cTzsD7K LCvl8rq6cbRqyFoSC15UKKNbQ/f+o/3LeGPoipr5NQZRMepxk2J/yBCNRXHvIbe6 oLMQJUgw7KKtvCrCUX9OSei4F09T1qsNrIYb7QafP5+v0zndAT7uKNivWrKGFrsh Uk9epoH3hIkvQERkpmzwJEJaq6oyqhoYQy7ZRGayEPwIdCyivJGZrVX0mZk1LX58 uc8u5grIslX9MqZEQWBweR5y7nISB494NGKmoCInu66U/+3DSOg3AGH2Rfw8PNFZ lMKdXzYoDgv2y6LeiLtTUKV4K1NBRXo0BhwSGbPw0o6C03/x003kG824Y+/naU75 6q05BZSia1PagPV3e0UAm0A2Rnjj/5uso2fEk0eGBSGM27jf9SQcSE8DVrEiLRd1 2N5uAXbMdfu4xACsEI1Uxu1KNOSQnUhBCy0X6Ppj1a083kLG7jg/126ebb05R8G4 MF79PFt+xUPSzmuKc/xwCdANtW+zzoyjYl5w6mwELBJ9veNbPShokGBTN/qzjXKZ vdr3/pXx95lRAzFnGOnETesm3IyObruU4K8NbMKd2b+eYa0w1WuZCKnutGLfsqxg byhCEw459e3P2g== =r6ln -----END PGP SIGNATURE----- Merge tag 'irq-core-2021-10-31' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq updates from Thomas Gleixner: "Updates for the interrupt subsystem: Core changes: - Prevent a potential deadlock when initial priority is assigned to a newly created interrupt thread.
