Hello,

the biggest thing is probably #1, no longer trying (and failing) to
charge replacement pages during migration and thus compaction.  The
rest is cleanups and tiny optimizations that move some checks out of
the charge and uncharge core paths that do not apply to all types of
pages alike.

Nice clean up Johannes.
Thanks!
