Subject: [PATCH AUTOSEL 4.9 14/17] lib/mpi: Fix building for powerpc with clang
Date: Thu, 30 Apr 2020 09:54:30 -0400	[thread overview]
Message-ID: <20200430135433.21204-14-sashal@kernel.org> (raw)
In-Reply-To: <20200430135433.21204-1-sashal@kernel.org>

From: Nathan Chancellor <natechancellor@gmail.com>

[ Upstream commit 5990cdee689c6885b27c6d969a3d58b09002b0bc ]

0day reports over and over on an powerpc randconfig with clang:

lib/mpi/generic_mpih-mul1.c:37:13: error: invalid use of a cast in a
inline asm context requiring an l-value: remove the cast or build with
-fheinous-gnu-extensions

Remove the superfluous casts, which have been done previously for x86
and arm32 in commit dea632cadd12 ("lib/mpi: fix build with clang") and
commit 7b7c1df2883d ("lib/mpi/longlong.h: fix building with 32-bit
x86").
