Subject: [PATCH] alpha: Wire up missing/new syscalls

This wire up the: fallocate, timerfd_create, timerfd_settime, timerfd_gettime
signalfd4, eventfd2, epoll_create1, dup3, pipe2, inotify_init1, preadv,
pwritev and rt_tgsigqueueinfo syscalls for the alpha port.

For umount2, alpha have an "old" and "new" version called: oldumount and umount;
so ignore umount2.
