Especially the "LOAD_PGD()" related operations. Should not we have two instances of the VHPT miss handler: one for the 3 and one for the 4 level page tables, and should no we copy the selected one into the trap table at init. time? (The source will be more readable, and one could see e.g. with "gdb vmlinux" how the final code will look like.) Thanks, Zoltan
