add mmap test in v7

updated patch

Moving to POST  for patch review.

Is the intent here to add a new hwcert test or a new qa use only test?

(In reply to comment #5)
> Is the intent here to add a new hwcert test or a new qa use only test?

According the meeting and follow-up discussion. I think we can put this kind of memory tests into existed memory test item, and creating a new qa/non-hwcert test for other kernel tier tests.

What is the run time?  What is the technical argument to add this test both as it compares to the existing v7 tests and why we should block a system which fails this test.  Is this duplicate to another portion of the existing v7 tests?

Comments on patch: probably nobody external will care that it is a ported test, perhaps those should be comments in code instead of announcement in the run logs?

add mmap test in v7 (new test)

I create a new tag "kerneltier1" for running Kernel Tier 1 tests, and
mark this test as non-certification test. Since there are many tests
needed to port to v7, customers maybe not accept if we integrate them
to existed tests unless we have a solid technical argument of adding
them.

New test basic information:

Runtime: 5m

Architecture: All

Function: test memory mapping by firstly allocating part of file space,
    mmaping whole file into memory, then allocating rest part of file
    space, then sync file with memory map. To validate mmap works, seek
    to certain file place, confirm the content is the same as in the
    memory map or not.

PASS/FAIL criteria: if the test returns non-zero value, the test would
fail, else the test gets passed.

Technical Argument: this test is used to test mmap() functionality, as
well as kernel memory functions. If the test fails, there may be
something incorrect with glibc, kernel or memory hardware. Additionally,
this test is ported from Kernel Tier 1 tests, which are used to run as
key tests suite before a kernel is confirmed to be usable.

Signed-off-by: Caspar Zhang <czhang>

Since it's not tagged as "certification" test, you cannot directly run via `v7 run -t kt1_mmap1', you should add -g option: -g osqa (existed tag) or -g kerneltier1 (required by Jeff and Kernel QE, newly added in the patch)

A running result:
