__cacheline_aligned is already part of the definition of DEFINE_RWLOCK
for -rt

However it is not always used for the tasklist_lock in non-rt, so it can't
simply be added to the definition of DEFINE_RWLOCK in non-rt, so I modified
the definition in fork.c
-ENOPARSE

The real question is whether RWLOCKS should be cacheline aligned in
general or the RT addon is just overkill. Slapping an ifdef around
does not answer that.

Thanks,
