Since the following commit arch_make_huge_pte() should be used directly in
generic memory subsystem as a platform provided page table helper, instead
of pte_mkhuge(). Change hugetlb_basic_tests() to call
arch_make_huge_pte() directly, and update its relevant documentation entry
as required.

It is enough to use a file name to cross-reference another rst document.
Jon says:
The right things will happen in the HTML output, readers of the
plain-text will know immediately where to go, and we don't have to add
the label clutter.
Drop reference markup and unnecessary labels and use plain file names.

Although pmd_present() might seem to indicate a valid and mapped pmd
entry, in reality it returns true when pmd_page() points to a valid page
in memory , regardless whether the pmd entry is mapped or not. Andrea
Arcangeli had earlier explained [1] the required semantics for
pmd_present(). This just updates the documentation for pmd_present() as
required.

so it will be consistent with code mm directory and with
Documentation/admin-guide/mm and won't be confused with virtual machines.
