Subject: [PATCH 4.9 36/37] ia64: tools: remove duplicate definition of ia64_mf() on ia64
Date: Mon, 26 Apr 2021 09:29:37 +0200 [thread overview]
Message-ID: <20210426072818.480614303@linuxfoundation.org> (raw)
In-Reply-To: <20210426072817.245304364@linuxfoundation.org>
From: John Paul Adrian Glaubitz <glaubitz@physik.fu-berlin.de>
[ Upstream commit f4bf09dc3aaa4b07cd15630f2023f68cb2668809 ]
The ia64_mf() macro defined in tools/arch/ia64/include/asm/barrier.h is
already defined in <asm/gcc_intrin.h> on ia64 which causes libbpf
failing to build:

cc1: all warnings being treated as errors
Thus, remove the definition from tools/arch/ia64/include/asm/barrier.h.
