Subject: [PATCH 3/8] arm64: Add prototypes for functions called by entry.S
Date: Thu,  3 Oct 2019 18:16:37 +0100	[thread overview]
Message-ID: <20191003171642.135652-4-james.morse@arm.com> (raw)
In-Reply-To: <20191003171642.135652-1-james.morse@arm.com>

Functions that are only called by assembly don't always have a
C header file prototype.

Add the prototypes before moving the assembly callers to C.
