[LTP] [PATCH v5 0/4] Hugetlb:Migrating the libhugetlbfs tests

[Tarun Sahu <tsahu@linux.ibm.com>]

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]
v3 -> v4
	1. Removed the needs_unlinked_hugetlb_file option in PATCH[1/4].
	2. Removed the redundant saved_oc_hugepages checks in PATCH[3/4].
	3. Updated the mntpoint checks in PATCH[1/4].
v4 -> v5
	1. Removed the needs_hugetlbfs check from needs_tmpdir function,
	because mntpoint is now mandatory option with needs_hugetlbfs.
	(PATCH[1/4])
