f730cf8ad8 fs/poll: Fix poll_notify for CONFIG_BUILD_KERNEL 
With flat addressing the user pollfd list is given directly to the
drivers that perform the notification. This is fine when the addressing
is flat, as there is no ambiguity on who gets notified and the fds memory
is always mapped.

For kernel mode with MMU this does not work. The notification must be done
via a temporary buffer allocated from kernel memory.

Thus, create a copy of the user fds and pass the copy to the drivers.
Afterwards copy the output events back to the user.

reason:
epoll_close -> close -> epoll_do_close (free inode)
                     -> inode_release  (reuse inode, crash)

fix:
use the global inode to match the fd which will return to user.

d452a05910 pollnotify: we should send poll events before semaphore incrementes. 
There is a good case on sim platform:
When we input some cmd and click enter key to start application in terminal,
this context will change to application from IDLE loop. Althrough entey key '\r'
has been received to recv buffer and complete post semaphore of reader, but
pollnotify may not be called because context change. So when application run
poll function, because no events happend and poll enter wait, context will
again change to IDLE loop, this pollnotify of IDLE loop will run to send poll
events, poll function of applicaton will wake up. It's wrong!
