Hmm, so I applied this and now my machine panics when we hit userspace. I
think the issue is that we no longer generate our syscall table in
arch/arm64/kernel/sys.c, because unistd.h is already included via
linux/syscalls.h but without the __SYSCALL definition.
So, a couple of questions:
(1) Is the lack of header guards actually causing you a problem?
(2) How did you test this?
I've dropped the patch.
