Subject: [PATCH 13/37] softirq: Macrofy softirq vectors
Date: Thu, 28 Feb 2019 18:12:18 +0100	[thread overview]
Message-ID: <20190228171242.32144-14-frederic@kernel.org> (raw)
In-Reply-To: <20190228171242.32144-1-frederic@kernel.org>

Define the softirq vectors through macros so that we can later include
them in the automated definition of lockdep usage states.
