[Xen-devel] page table modification in Xen

Hi, folks.
I'm trying to intercept every page table(L1) modification in Xen. So, I'm tracking all mappings to build a sort of reverse mapping table. So I'm intercepting mapping changes in mod_l1_entry() and [alloc,free]_l1_table() and it seemed to work for some page tables, but I'm still missing some mapping changes. where else these mapping can change? where to intercept? I'm working on IA32, no pae,.
thanks in advance.
