Subject: [RFC PATCH v1 3/9] genirq: Introduce irq_is_percpu_devid()
Date: Thu, 7 Sep 2017 16:25:36 -0700	[thread overview]
Message-ID: <20170907232542.20589-4-paul.burton@imgtec.com> (raw)
In-Reply-To: <20170907232542.20589-1-paul.burton@imgtec.com>

In preparation for allowing code to handle both percpu_devid interrupts
using the percpu interrupt APIs, and non-percpu_devid but still percpu
interrupts with the regular interrupt APIs, introduce a new
irq_is_percpu_devid() helper function to allow callers to check whether
an interrupt has the IRQ_PER_CPU_DEVID flag set.
