Subject: [PATCH 3.17-rc4 v7 3/6] arm64: Introduce dummy version of asm/fiq.h
Date: Wed, 17 Sep 2014 09:10:15 -0700 [thread overview]
Message-ID: <1410970218-28847-4-git-send-email-daniel.thompson@linaro.org> (raw)
In-Reply-To: <1410970218-28847-1-git-send-email-daniel.thompson@linaro.org>
Drivers that are shared between arm and arm64 and which employ
FIQ on arm cannot include asm/fiq.h without #ifdef'ing. This patch
introduces a dummy version of asm/fiq.h to arm64 to avoid this.
