After commit f7d5bcd35d42 ("selftests: kselftest: Mark functions that
unconditionally call exit() as __noreturn"), ksft_exit_...() functions
are marked as __noreturn, which means the return type should not be
'int' but 'void' because they are not returning anything (and never were
since exit() has always been called).
To facilitate updating the return type of these functions, remove
'return' before the calls to ksft_exit_...(), as __noreturn prevents the
compiler from warning that a caller of the ksft_exit functions does not
return a value because the program will terminate upon calling these
functions.

__FILE__ is not guaranteed to exist in current dir. Replace that with
argv[0] for memory map test.

Some architectures don't support userfaultfd. Skip running the whole test
on them instead of registering the failure.

Add pagemap ioctl tests. Add several different types of tests to judge
the correction of the interface.
