[LTP] [PATCH v4 0/8] Cleanup the mmap testing suite

[Andrea Cervesato]

Some of the tests in the mmap testing suites are using old API, having
documentation which is not linked to the metadata or need to be cleaned
up a bit. This patch-set is meant to fix these issues. mmap11 is for
IA64 only and that will require a separate patch and discussion.
