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.
Before,
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'
