Hi Pavel,

Actually, thinking a bit more about this, it might make sense to remove
__paginginit altogether and keep only __meminit.
Looking at the original commit, I think that it was put as a way to abstract it.

After the patchset [1] has been applied, only two functions marked as __paginginit
remain, so it will be less hassle to replace that with __meminit.

I will send a v2 tomorrow to be applied on top of [1].
