user-mode pointers. Change types used in the structures definitions to
properly-sized architecture-specific types.

what Linux does. This is because robust futexes are mostly
userspace thing which we cannot alter. Two syscalls maintain
pointer to userspace list and when process exits a routine
walks this list waking up processes sleeping on futexes
from that list.

so the annoying message is not printed.
o Don't warn about FUTEX_FD not being implemented
and return ENOSYS instead of 0 (eg. success).
o Clear FUTEX_PRIVATE_FLAG as we actually implement
only private futexes so there is no reason to
return ENOSYS when app asks for a private futex.
We don't reject shared futexes because they worked
just fine with our implementation so far.

semi-automatic style(9)
The futex stuff already differs a lot (only a small part does not differ)
from NetBSD, so we are already way off and can't apply changes from NetBSD
automatically. As we need to merge everything by hand already, we can even
make the files comply to our world order.
Please don't style(9) the NetBSD code, we want to stay in sync. Not imported
on a vendor branch since we need local changes.
