    mm: move hugepage test examples to tools/testing/selftests/vm · f0f57b2b
    Dave Young authored
    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
