Documentation/vm: use better value for MAP_HUGETLB

89bbfb6b · Carlo Marcelo Arenas Belon <[email protected]> · 2010-05-23 17:02:30 -07:00

documentation: slightly more correct value for MAP_HUGETLB in map_hugetlb.c

still not correct for alpha, mips, parisc or xtensa but working out of
the box in the most common architectures without having to deal with
complicated macros or including architecture specific headers.
