We currently do not document MAP_HUGETLB, which is closely related and 
not really simple to describe.  The manual page and kernel documentation 
do not cover it in detail, either.  The page size selection in 
particular is missing, and I would have to research how an application 
can discover supported hugepage sizes.

In short, this is not exactly a trivial request, and I would kindly ask 
you to reconsider.

Thanks,
Florian
