The documentation of the xvYCC601 Y'CbCr encoding was part of the SMPTE 170M (SDTV) colorspace, but it should have been part of the Rec. 709 (HDTV) colorspace as per the xvYCC standard.

2015-02-26[media] media.h: mark alsa struct in media_entity_desc as TODOHans Verkuil1-1/+15
The alsa struct in struct media_entity_desc is now marked as deprecated. However, the alsa struct should remain as it is since it cannot be replaced by a simple major/minor device node description. The alsa struct was designed to be used as an alsa card description so V4L2 drivers could use this to expose the alsa card that they create to carry the captured audio. Such a card is not just a PCM device, but also needs to contain the alsa subdevice information, and it may map to multiple devices, e.g. a PCM and a mixer device, such as the au0828 usb stick creates. This is exactly as intended and this cannot and should not be replaced by a simple major/minor. However, whether this information is in the right form for an ALSA device such that it can handle udev renaming rules as well is another matter. So mark this alsa struct as TODO and document the problems involved. Updated the documentation as well to reflect this and to add the 'major' and 'minor' field documentation. Updated the documentation to clearly state that struct dev is to be used for (sub-)devices that create a single device node. Other devices need their own structure here.

This new function allows us to support hole-punch for DAX files by zeroing a partial page, as opposed to the dax_truncate_page() function which can only truncate to the end of the page. Reimplement dax_truncate_page() to call dax_zero_page_range().

2015-02-16ext2: get rid of most mentions of XIP in ext2Matthew Wilcox1-2/+3
To help people transition, accept the 'xip' mount option (and report it in /proc/mounts), but print a message encouraging people to switch over to the 'dax' option.

2015-02-16vfs: remove get_xip_memMatthew Wilcox2-10/+0
All callers of get_xip_mem() are now gone. Remove checks for it, initialisers of it, documentation of it and the only implementation of it. Also remove mm/filemap_xip.c as it is now empty. Also remove documentation of the long-gone get_xip_page().

2015-02-16dax: replace XIP documentation with DAX documentationMatthew Wilcox3-73/+92
Based on the original XIP documentation, this documents the current state of affairs, and includes instructions on how users can enable DAX if their devices and kernel support it.
