Pull documentation update from Jonathan Corbet:
 "A fairly normal cycle for documentation stuff. We have a new document
  on perf security, more Italian translations, more improvements to the
  memory-management docs, improvements to the pathname lookup
  documentation, and the usual array of smaller fixes.

  As is often the case, there are a few reaches outside of
  Documentation/ to adjust kerneldoc comments"

media: docs: fix some GPL licensing ambiguity at the text

2018-12-17T15:57:20+00:00

Those files are meant to be dual GPL 2.0 and GFDL without
implicit sections. However, by a wrong cut-and-paste, I ended
by applying a GPL 2+ license text to it, while still using the
GPL 2.0 SPDX tag, with would cause an ambiguity about the
licensing model.

Solve this by explicitly mentioning that the dual licensing
is between GPL 2.0 and GFDL and correcting the text.

media: v4l2: clarify H.264 loop filter offset controls

2018-12-07T13:17:21+00:00

The venus and s5p-mfc drivers add the loop filter alpha/beta offset
controls V4L2_CID_MPEG_VIDEO_H264_LOOP_FILTER_ALPHA/BETA with a range of
-6 to +6, inclusive. This is exactly the range specified for the slice
header fields slice_alpha_c0_offset_div2 and slice_beta_offset_div2,
which store half the actual filter offsets FilterOffsetA/B.

Clarify that this control contains the halved offsets.
