Subject: [RESEND PATCH 1/2] irqdesc: Add function to identify percpu_devid irqs
Date: Tue, 24 Oct 2017 15:46:10 +0100	[thread overview]
Message-ID: <20171024144610.GC14568@arm.com> (raw)
In-Reply-To: <20171013174422.GA6050@leverpostej>

I was hoping to merge this one via arm64 since it now has Marc's
Reviewed-by, but I'd really like your Ack on it too, if you don't mind.

Could you take a look, please?

Thanks,

Will
