MIPS: secure_computing, syscall audit: syscall number should in r2, not r0.
As it is, audit_syscall_entry() and secure_computing() get the bogus value (0, in fact) Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Cc: linux-kernel@vger.kernel.org Cc: linux-arch@vger.kernel.org Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/1697/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
