Create the config file in each directory of testcase which need
more kernel configuration than the default defconfig. User could
use these configs with merge_config.sh script:
Enable config for specific testcase:
(export ARCH=xxx #for cross compiling)
./scripts/kconfig/merge_config.sh .config \
tools/testing/selftests/xxx/config
Enable configs for all testcases:
(export ARCH=xxx #for cross compiling)

Test the mmap() flag, and the mlockall() flag. These tests ensure that
pages are not faulted in until they are accessed, that the pages are
unevictable once faulted in, and that VMA splitting and merging works with
the new VM flag. The second test ensures that mlock limits are respected.
Note that the limit test needs to be run a normal user.
Also add tests to use the new mlock2 family of system calls.

Add the usr/include subdirectory of the top-level tree to the include
path, and make sure to include headers without relative paths to make
sure the sanitized headers get picked up. Otherwise the compiler will
not be able to find the linux/compiler.h header included by the non-
sanitized include/uapi/linux/userfaultfd.h.
While at it, make sure to only hardcode the syscall numbers on x86 and
PowerPC if they haven't been properly picked up from the headers.

Commit commit 5bbe3547aa3b ("mm: allow compaction of unevictable pages")
introduced a sysctl that allows userspace to enable scanning of locked
pages for compaction. This patch introduces a new test which fragments
main memory and attempts to allocate a number of huge pages to exercise
this compaction logic.
Tested on machines with up to 32 GB RAM. With the patch a much larger
number of huge pages can be allocated than on the kernel without the
patch.
Example output:
On a machine with 16 GB RAM:
sudo make run_tests vm
...
-----------------------
running compaction_test
-----------------------
No of huge pages allocated = 3834
[PASS]

When MAP_HUGETLB memory is unmapped, the length must be hugepage aligned,
otherwise it fails with -EINVAL.
All tests currently behave correctly, but it's better to explcitly test
the return value for completeness and document the requirement, especially
if users copy map_hugetlb.c as a sample implementation.

This adds make install support to selftests. The basic usage is:
$ cd tools/testing/selftests
$ make install
That installs into tools/testing/selftests/install, which can then be
copied where ever necessary.
The install destination is also configurable using eg:
$ INSTALL_PATH=/mnt/selftests make install
The implementation uses two targets in the child makefiles. The first
"install" is expected to install all files into $(INSTALL_PATH).
The second, "emit_tests", is expected to emit the test instructions (ie.
bash script) on stdout. Separating this from install means the child
makefiles need no knowledge of the location of the test script.

This adds a Make include file which most selftests can then include to
get the run_tests logic.
On its own this has the advantage of some reduction in repetition, and
also means the pass/fail message is defined in fewer places.
However the key advantage is it will allow us to implement install very
simply in a subsequent patch.
The default implementation just executes each program in $(TEST_PROGS).
We use a variable to hold the default implementation of $(RUN_TESTS)
because that gives us a clean way to override it if necessary, ie. using
override. The mount, memory-hotplug and mqueue tests use that to provide
a different implementation.
Tests are not run via /bin/bash, so if they are scripts they must be
executable, we add a+x to several.

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
