Subject: [PATCH 3/8] vop: Add definition of readq/writeq if missing
Date: Wed, 16 Jan 2019 17:32:48 +0100 [thread overview]
Message-ID: <20190116163253.23780-4-vincent.whitchurch@axis.com> (raw)
In-Reply-To: <20190116163253.23780-1-vincent.whitchurch@axis.com>
Include <linux/io-64-nonatomic-lo-hi.h> so that readq/writeq are
replaced by two readl/writel on systems that do not support them. The
values read/written are pointers which will be 32-bit on 32-bit systems
so the non-atomicity should not matter.
Signed-off-by: Vincent Whitchurch <vincent.whitchurch@axis.com>
