Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq updates from Thomas Gleixner:
- Consolidation of softirq pending:
The softirq mask and its accessors/mutators have many implementations
scattered around many architectures. Most do the same things
consisting in a field in a per-cpu struct (often irq_cpustat_t)
accessed through per-cpu ops. We can provide instead a generic
efficient version that most of them can use. In fact s390 is the only
exception because the field is stored in lowcore.
- Support for level!?! triggered MSI (ARM)
Over the past couple of years, we've seen some SoCs coming up with
ways of signalling level interrupts using a new flavor of MSIs, where
the MSI controller uses two distinct messages: one that raises a
virtual line, and one that lowers it. The target MSI controller is in
charge of maintaining the state of the line.
This allows for a much simplified HW signal routing (no need to have
hundreds of discrete lines to signal level interrupts if you already
have a memory bus), but results in a departure from the current idea
the kernel has of MSIs.
- Support for Meson-AXG GPIO irqchip
- Large stm32 irqchip rework (suspend/resume, hierarchical domains)
- More SPDX conversions
