BookE does not have mtmsrd, switch to use wrteei to enable MSR[EE].

This wasn't caught by QEMU because it executes mtmsrd just fine on B

Hi Nick,
Thanks a lot for your patch! We will test it as soon as possible. You're

Do the same as commit f8f0d0b6fa20 ("mm: ptdump: reduce level numbers
by 1 in note_page()") and add missing p4d level.
This will align powerpc to the users of generic ptdump.

note_page_update_state() doesn't use page_size. Remove it.
Could also be removed to note_page() but as a following patch
will remove all current users of note_page(), just leave it as
is for now.
