Subject: [PATCH v4 6/8] arm: Break cyclic percpu include
Date: Tue, 23 Jun 2020 10:36:51 +0200 [thread overview]
Message-ID: <20200623083721.454517573@infradead.org> (raw)
In-Reply-To: 20200623083645.277342609@infradead.org
In order to use <asm/percpu.h> in irqflags.h, we need to make sure
asm/percpu.h does not itself depend on irqflags.h.
