Dhinakaran Pandiyan f4c0468e4b drm/atomic: Handle 64-bit return from drm_crtc_vblank_count() 
570e86963a ("drm: Widen vblank count to 64-bits [v3]") changed the
return type for drm_crtc_vblank_count() to u64.

The flip ioctl receives a 32-bit target sequence from user space and is
compared against the current sequence from drm_crtc_vblank_count(). So,
typecast return from drm_crtc_vblank_count() explicitly to add clarity.

__drm_crtcs_state.last_vblank_count however only ever stores the value from
drm_crtc_vblank_count() and can be upgraded to u64.

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.
