JFYI, the change

-#define audit_syscall_entry(ta,a,b,c,d,e) do { ; } while (0)
+static inline void audit_syscall_entry(int arch, int major, unsigned long a0,
+ unsigned long a1, unsigned long a2,
+ unsigned long a3)
+{ }

uncovers a bug on OpenRISC.


audit_syscall_entry(audit_arch(), regs->gpr[11],
regs->gpr[3], regs->gpr[4],
regs->gpr[5], regs->gpr[6]);

just expanded to nothing if CONFIG_AUDITSYSCALL was not set.
Now, it fails to compile with:

arch/openrisc/kernel/ptrace.c:190:2: error: implicit declaration of
function 'audit_arch'
