Since it's just get/put_page_from_l1e I think we should just duplicate 
the required bits in the shadow code. Could the required parts be 
merged into shadow_get/put_page_from_l1e()? For example, non of the 
I/O-page mapping stuff is needed at all yet. We could for now BUG_ON 
!valid_mfn() and flags in L1_DISALLOW_MASK.
Could you split your original patch into the updated changes to shadow 
mode, and a separate patch for the actual mapcache logic?
