Subject: [PATCH v2 03/19] arm64: asm-offsets: Remove potential circular dependency
Date: Mon, 11 Dec 2017 14:49:21 +0000 [thread overview]
Message-ID: <20171211144937.4537-4-marc.zyngier@arm.com> (raw)
In-Reply-To: <20171211144937.4537-1-marc.zyngier@arm.com>
So far, we've been lucky enough that none of the include files
that asm-offsets.c requires do include asm-offsets.h. This is
about to change, and would introduce a nasty circular dependency...
Let's now guard the inclusion of asm-offsets.h so that it never
gets pulled from asm-offsets.c.
Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
