Hugetlbfs file mappings are handled differently than regular files:
- pager_req_create will tell us the file is in a hugetlbfs
- allocate memory upfront, we need to fail if not enough memory
- the memory needs to be given again if another process maps the same
file
This implementation still has some hacks, in particular, the memory
needs to be freed when all mappings are done and the file has been
deleted/closed by all processes.
We cannot know when the file is closed/unlinked easily, so clean up
memory when all processes have exited.
To test, install libhugetlbfs and link a program with the additional
LDFLAGS += -B /usr/share/libhugetlbfs -Wl,--hugetlbfs-align
Then run with HUGETLB_ELFMAP=RW set, you can check this works with
HUGETLB_DEBUG=1 HUGETLB_VERBOSE=2

Add new file with common functions for tests to use.
- loads config file
- checks for mcexec etc
- checks for LTP and OSTEST if required
- handle mcstop / mcreboot if required, and provide function for it
At the same time, make a few changes to mck_test_config:
- move to ~/.mck_test_config
- add boot params to the config, tests the require specific params can
overwite it
- make the config "set-if-variable-is-empty", so someone can overwrite
any param by setting the environment value e.g. LTP=.... ./test.sh
will use the value given

Device map with MAP_PRIVATE is copied when forking using copy_user_pte.
So the map isn't copied by those statements.
