Kan Liang 626af862da perf top: Fix annoying fallback message on older kernels 
On older (e.g. v4.4) kernels, an annoying fallback message can be
observed in 'perf top':

	┌─Warning:──────────────────────┐
	│fall back to non-overwrite mode│
	│                               │
	│                               │
	│Press any key...               │
	└───────────────────────────────┘

The 'perf top' utility has been changed to overwrite mode since commit
ebebbf0823 ("perf top: Switch default mode to overwrite mode").

For older kernels which don't have overwrite mode support, 'perf top'
will fall back to non-overwrite mode and print out the fallback message
using ui__warning(), which needs user's input to close.

The fallback message is not critical for end users. Turning it to debug
message which is printed when running with -vv.

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.
