Subject: [PATCH] compat: fix sys_fanotify_mark

Commit 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.
