[Xen-devel] pagetable maps itself

[David Becker <becker@xxxxxxxxxxx>]

I'm trying to put the shared_info page entry(0x001b6007) in
a pte at 0xc0116404 and get
(XEN) DOM77: (file=memory.c, line=1821) PTWR failure! Pagetable maps itself at 
c0116404

Doubtless this is operator error, but I'm at a loss as to what my error is.
I am confident the pte address is correct and that the domain build says the 
share_info mfn is 0x1b6.

The pgd page entry for 0xc0116404 is 0x01c28067, which also appears OK.  

I don't understand how my table is mapping itself when I write that pte.
