-Subject: x86/32on64: don't allow recursive page tables from L3
-
-L3 entries are special in PAE mode, and hence can't reasonably be used
-for setting up recursive (and hence linear) page table mappings. Since
-abuse is possible when the guest in fact gets run on 4-level page
-tables, this needs to be excluded explicitly.
-
-This is XSA-185.
