Linus Torvalds cb69d86550 Updates for the interrupt subsystem: ... - Core: - Remove a global lock in the affinity setting code The lock protects a cpumask for intermediate results and the lock causes a bottleneck on simultaneous start of multiple virtual machines. Replace the lock and the static cpumask with a per CPU cpumask which is nicely serialized by raw spinlock held when executing this code. - Provide support for giving a suffix to interrupt domain names. That's required to support devices with subfunctions so that the domain names are distinct even if they originate from the same device node. - The usual set of cleanups and enhancements all over the place - Drivers: - Support for longarch AVEC interrupt chip - Refurbishment of the Armada driver so it can be extended for new variants. - The usual set of cleanups and enhancements all over the place -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmbn5p8THHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoRFtD/43eB3h5usY2OPW0JmDqrE6qnzsvjPZ 1H52BcmMcOuI6yCfTnbi/fBB52mwSEGq9Dmt1GXradyq9/CJDIqZ1ajI1rA2jzW2 YdbeTDpKm1rS2ddzfp2LT2BryrNt+7etrRO7qHn4EKSuOcNuV2f58WPbIIqasvaK uPbUDVDPrvXxLNcjoab6SqaKrEoAaHSyKpd0MvDd80wHrtcSC/QouW7JDSUXv699 RwvLebN1OF6mQ2J8Z3DLeCQpcbAs+UT8UvID7kYUJi1g71J/ZY+xpMLoX/gHiDNr isBtsuEAiZeNaFpksc7A6Jgu5ljZf2/aLCqbPLlHaduHFNmo94x9KUbIF2cpEMN+ rsf5Ff7AVh1otz3cUwLLsm+cFLWRRoZdLuncn7rrgB4Yg0gll7qzyLO6YGvQHr8U Ocj1RXtvvWsMk4XzhgCt1AH/42cO6go+bhA4HspeYykNpsIldIUl1MeFbO8sWiDJ kybuwiwHp3oaMLjEK4Lpq65u7Ll8Lju2zRde65YUJN2nbNmJFORrOLmeC1qsr6ri dpend6n2qD9UD1oAt32ej/uXnG160nm7UKescyxiZNeTm1+ez8GW31hY128ifTY3 4R3urGS38p3gazXBsfw6eqkeKx0kEoDNoQqrO5gBvb8kowYTvoZtkwMGAN9OADwj w6vvU0i+NIyVMA== =JlJ2 -----END PGP SIGNATURE----- Merge tag 'irq-core-2024-09-16' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq updates from Thomas Gleixner: "Core: - Remove a global lock in the affinity setting code The lock protects a cpumask for intermediate results and the lock causes a bottleneck on simultaneous start of multiple virtual machines.
