As the confusing naming indicates, this test has some overlap with
pre-existing tests. Would be nice to merge them eventually. But since it
is only test code, cleanliness is much less important than mere existence.

thuge-gen was forgotten. Fix it by removing the duplication, so we don't
get too many repeats.

In case this ever gets scripted, it should return 0 on success and 1 on
failure. Parsing the output should be left to meatbags.

hugepage-mmap.c, hugepage-shm.c and map_hugetlb.c in Documentation/vm are
simple pass/fail tests, It's better to promote them to
tools/testing/selftests.
Thanks suggestion of Andrew Morton about this. They all need firstly
setting up proper nr_hugepages and hugepage-mmap need to mount hugetlbfs.
So I add a shell script run_vmtests to do such work which will call the
three test programs and check the return value of them.
Changes to original code including below:
a. add run_vmtests script
b. return error when read_bytes mismatch with writed bytes.
c. coding style fixes: do not use assignment in if condition
[akpm@linux-foundation.org: build the targets before trying to execute them]
[akpm@linux-foundation.org: Documentation/vm/ no longer has a Makefile. Fixes "make clean"]
