Arnaldo Carvalho de Melo 94e87a8bd5 perf hists browser: Remove leftover from row returned from refresh
The per-browser screen refresh routine (ui_browser->refresh()) should
return the first row that should be cleaned after the rows just printed,
in case not all rows available on the screen gets filled.

When moving the extra title lines logic from the hists browser to the
generic ui_browser class, one piece of that logic remained in the hists
browser and then when going back from the annotate browser to the hists
browser in a case where fewer lines were displayed in the hists browser,
for instance when filtering the entries per substring, one line of the
annotate browser would remain on the screen, fix that.

Example of the screen artifact:

================================================================================
Samples: 73K of event 'cycles:ppp', 4000 Hz, Event count (approx.): 45172901394
Overhead  Shared O  Symbol
   0.30%  [kernel]  [k] __indirect_thunk_start
   0.09%  [kernel]  [k] __x86_indirect_thunk_r10
       │      lfence
================================================================================

Here from 'perf top' the view was zoomed with '/thunk' to functions
having that substring, then the first was annotated and from the
annotate browser ESC was pressed, then the first lines were overwritten,
but the 'lfence' line remained due to the off by one bug fixed in this
cset.

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.
