Adhemerval Zanella bc6d79f4ae malloc: Improve MAP_HUGETLB with glibc.malloc.hugetlb=2 
Even for explicit large page support, allocation might use mmap without
the hugepage bit set if the requested size is smaller than
mmap_threshold.  For this case where mmap is issued, MAP_HUGETLB is set
iff the allocation size is larger than the used large page.

To force such allocations to use large pages, also tune the mmap_threhold
(if it is not explicit set by a tunable).  This forces allocation to
follow the sbrk path, which will fall back to mmap (which will try large
pages before galling back to default mmap).

Checked on x86_64-linux-gnu.
