The usual comment for such changes: could you please clean this up and
just use something like "depends on HAVE_ARCH_AUDITSYSCALL"?
Do you agree to this change?
If so, I can create a patch, but have some concerns:
1) I can't verify it on other architectures than (arm &) arm64.
2) Some architectures (microblaze, mips, openrisc) are not listed here, but
their ptrace.c have a call to audit_syscall_entry/exit().
(audit_syscall_entry/exit are null if !AUDITSYSCALL, though)
So I'm afraid that the change might break someone's assumption.
Thanks,
