[PATCH] Cleaned /dev/epoll patch ...

[Davide Libenzi]

The /dev/epoll patch has been cleaned and slightly changed :

1) moved the file callback list handling from fs/file.c to fs/fcblist.c

2) moved the functions definitions from include/linux/file.h to
        include/linux/fcblist.h

3) renamed the patch from /dev/poll to /dev/epoll ( event poll )

4) renamed the devpoll.c(.h) files into eventpoll.c(.h)

5) configuration variable from CONFIG_DEVPOLL to CONFIG_EVENTPOLL

6) fixed a locking issue on SMP

7) kmalloc/vmalloc switch for big chunks of mem

8) increased the maximum number of fds to 128000 ( maybe I'll change this to be
        unbounded )

9) changed device MINOR to 124
