Subject: [PATCH 12/13] MIPS: ip22: fix ip28 build for modern gcc
Date: Tue, 17 Jan 2017 16:18:46 +0100 [thread overview]
Message-ID: <20170117151911.4109452-12-arnd@arndb.de> (raw)
In-Reply-To: <20170117151911.4109452-1-arnd@arndb.de>
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.
