Merge tag 'irq-core-2020-12-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq updates from Thomas Gleixner: "This is the second attempt after the first one failed miserably and got zapped to unblock the rest of the interrupt related patches. A treewide cleanup of interrupt descriptor (ab)use with all sorts of racy accesses, inefficient and disfunctional code. The goal is to remove the export of irq_to_desc() to prevent these things from creeping up again" * tag 'irq-core-2020-12-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (30 commits) genirq: Restrict export of irq_to_desc() xen/events: Implement irq distribution xen/events: Reduce irq_info:: Spurious_cnt storage size xen/events: Only force affinity mask for percpu interrupts xen/events: Use immediate affinity setting xen/events: Remove disfunct affinity spreading xen/events: Remove unused bind_evtchn_to_irq_lateeoi() net/mlx5: Use effective interrupt affinity net/mlx5: Replace irq_to_desc() abuse net/mlx4: Use effective interrupt affinity net/mlx4: Replace irq_to_desc() abuse PCI: mobiveil: Use irq_data_get_irq_chip_data() PCI: xilinx-nwl: Use irq_data_get_irq_chip_data() NTB/msi: Use irq_has_action() mfd: ab8500-debugfs: Remove the racy fiddling with irq_desc pinctrl: nomadik: Use irq_has_action() drm/i915/pmu: Replace open coded kstat_irqs() copy drm/i915/lpe_audio: Remove pointless irq_to_desc() usage s390/irq: Use irq_desc_kstat_cpu() in show_msi_interrupt() parisc/irq: Use irq_desc_kstat_cpu() in show_interrupts() ...
