I thought about it but it doesn't prevent new inclusions of asm/guest_access.h.
For instance, the following would still compile:
#include <xen/guest_access.h>
[...]
#include <asm/guest_access.h>
But where's the problem with this? The first #include will already
have resulted in the inclusion of asm/guest_access.h, so the second
#include is simply a no-op.
A couple of reasons:
1) I don't consider this solving completely your original request [1]
2) I don't see how this is more important to prevent including
<asm/guest_access.h> before and not after. Both will still compile fine,
we just want to avoid it.
