[GIT PULL FOR v3.6] Core and vb2 enhancements

[Hans Verkuil <hverkuil@xxxxxxxxx>]

Hi all,

This is the pull request for the RFC patch series adding core and vb2 enhancements.

Changes since the RFCv3 (http://www.spinics.net/lists/linux-media/msg49583.html):

- Added vb2_fop_get_unmapped_area (thanks to Scott Jiang for catching that one).
- Added vb2_ops_wait_prepare/finish helpers and use them in pwc.
- Improved the locking documentation in v4l2-framework.txt.
- Rebased to the latest 3.6 code.

Regards,

	Hans
