Subject: [RFC PATCH 12/12] selftests/seccomp: Add powerpc support
Date: Wed, 15 Jul 2015 17:37:14 +1000	[thread overview]
Message-ID: <1436945834-26660-12-git-send-email-mpe@ellerman.id.au> (raw)
In-Reply-To: <1436945834-26660-1-git-send-email-mpe@ellerman.id.au>

Wire up the syscall number and regs so the tests work on powerpc.
