Hi,
Libhugetlbfs is not being maintained actively, and some distro is dropping
support for it. There are some tests that are good for testing hugetlb
functionality in kernel.

As per previous dicussion in RFC[1], Here, this patch series consists
of hugetlb tests taken from libhugetlbfs modified to work in ltp
environment.

Based on suggestion[2], I am reposting the patches again. Also, I added
suggested changes at [3].

v1 -> v2
1. In (brk near huge) test [PATCH 1/3] removed unused library
function test_addr_huge() and read_maps().
v2 -> v3
1. Added a new patch commit for two new flags "needs_hugetlbfs" &
"needs_unlinked_hugetlb_file" in tst_test and modified tests to use
these flags.
2. Added taint check in test [PATCH 1/3].
3. Removed redundant Hopt and nr_opt option.
4. Corrected pre-processor ARCH based conditional flags in test
[PATCH 1/3]
