Subject: [PATCH 4.10 10/48] MIPS: ip22: Fix ip28 build for modern gcc
Date: Thu, 16 Mar 2017 23:29:54 +0900 [thread overview]
Message-ID: <20170316142921.306302744@linuxfoundation.org> (raw)
In-Reply-To: <20170316142920.761502205@linuxfoundation.org>
4.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@arndb.de>
commit 23ca9b522383d3b9b7991d8586db30118992af4a upstream.
kernelci reports a failure of the ip28_defconfig build after upgrading its
gcc version:
arch/mips/sgi-ip22/Platform:29: *** gcc doesn't support needed option -mr10k-cache-barrier=store. Stop.
The problem apparently is that the -mr10k-cache-barrier=store option is now
rejected for CPUs other than r10k. Explicitly including the CPU in the
check fixes this and is safe because both options were introduced in
gcc-4.4.
