Ralf, I'm sorry for misunderstanding.  Original kernel does panic in this situation. 
In my patch it went to panic with
+		else if (pgd_page_vaddr(*pgd) != pgd_page_vaddr(*pgd_k))
+				goto no_context;

Actually it was the reason of this patch.

But looks like we need go immediately to no_context for 64 bit and do not do this checks.

Maxim.
