On ppc64 with 64k pages, xfsdump fails with several assertions about page size
in relation to various other sizes.  In particular, these:

all trip.  xfsdump seems a bit confused about "PGSZ" (hard-coded to 4096) and
pgsz (actual machine page size) and what is part of the dump format, what is
optimal IO, what is required for proper IO alignment, etc.  However, I'll note
that simply commenting out the above ASSERTs on 64k ppc64 did allow all of the
xfsdump xfsqa tests to pass (with a kernel that has my fixed compat ioctls
hooked up, that is).
