I was going to rediff the memory present patches, but as -mm has
picked these up already here is a simple patch to clean up this
errant comment and address a benign call to memory_present().
Applies onto the existing patches.
-apw
Tidy up the comments for the ppc64 flat memory support and fix
a currently benign double call to memory_present() for the first
memory block.
