History
Mark Johnston 847ab36bf2 Include the psind in data returned by mincore(2). 
Currently we use a single bit to indicate whether the virtual page is
part of a superpage.  To support a forthcoming implementation of
non-transparent 1GB superpages, it is useful to provide more detailed
information about large page sizes.

The change converts MINCORE_SUPER into a mask for MINCORE_PSIND(psind)
values, indicating a mapping of size psind, where psind is an index into
the pagesizes array returned by getpagesizes(3), which in turn comes
from the hw.pagesizes sysctl.  MINCORE_PSIND(1) is equal to the old
value of MINCORE_SUPER.

For now, two bits are used to record the page size, permitting values
of MAXPAGESIZES up to 4.
