Subject: [PATCH 0/2] irqchip/genirq/msi: Use irq_domain_alloc_irqs()
Date: Tue, 13 Dec 2022 15:08:42 +0100	[thread overview]
Message-ID: <20221213140844.15470-1-johan+linaro@kernel.org> (raw)

When reworking the irqdomain locking I noticed that we had quite a few
users of the __irq_domain_alloc_irqs() interface which was initially
only intended for some legacy x86 use cases.

This first patch updates the irqchip driver so that the
irq_domain_alloc_irqs() wrapper is instead used consistently.

The second patch adds a matching irq_domain_alloc_irqs_affinity() helper
which can be used when an affinity hint needs to be provided and updates
the sole user.

With this update to gpiolib:

	https://lore.kernel.org/lkml/20221213135227.14398-1-johan+linaro@kernel.org

the only remaining users of the full interface (with preallocated
descriptors) are the two original calls in x86/io_apic and the later
added one for IPI.
