[GIT PATCHES FOR 3.2] add poll_requested_events() function

[Hans Verkuil]

Since there have been no more comment on RFCv4 of this patch series
(http://comments.gmane.org/gmane.linux.kernel/1196926), I'm posting this
pull request for v3.2.

I never received any acks or comments from Al Viro (or anyone else from
linux-fsdevel for that matter), so I'm following Andrew's suggestion and I just
go ahead with this.

This series should be pulled in via the media git repository since the media
drivers are the primary users of the new poll_requested_events() function.

Regards,

	Hans
