Maarten Lankhorst 3a0d137de0 drm/i915: Nuke skl_update_plane debug message from the pipe update critical section 
printks are slow so we should not be doing them from the vblank evade
critical section. These could explain why we sometimes seem to
blow past our 100 usec deadline.

The problem has been there ever since commit c331879ce8 ("drm/i915:
skylake sprite plane scaling using shared scalers.") but it may not have
been readily visible until commit e1edbd44e2 ("drm/i915: Complain
if we take too long under vblank evasion.") increased our chances
of noticing it.

README 

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
