Arnd Bergmann f8109d9e7d infiniband: cxgb4: use ktime_get for timestamps
The debugfs file prints the difference between host timestamps as a
seconds/nanoseconds tuple, along with a 64-bit nanoseconds hardware
timestamp. The host time is read using getnstimeofday() which is
deprecated because of the y2038 overflow, and it suffers from time jumps
during settimeofday() and leap seconds.

Converting to ktime_get_ts64() would solve those two, but I'm going
a little further here by changing to ktime_get() and printing 64-bit
nanoseconds on both host and hw timestamps.  This simplifies the code
further and makes the output easier to understand.

The format of the debugfs file obviously changes here, but this should
only be read by humans and not scripts, so I assume it's fine.

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.
