Subject: compat: fix sys_fanotify_mark
91c2e0bcae72 ("unify compat fanotify_mark(2), switch to
COMPAT_SYSCALL_DEFINE") added a new unified compat fanotify_mark syscall
to be used by all architectures. Unfortunately the unified version merges
the split mask parameter in a wrong way: the lower and higher word got
swapped.
This was discovered with glibc's tst-fanotify test case.
