Sometimes we may need to reload the browser to update the output since some options are changed. This patch creates a new key K_RELOAD. Once the __cmd_report() returns K_RELOAD, it would repeat the whole process, such as, read samples from data file, sort the data and display in the browser. v5: --- 1. Fix the 'make NO_SLANG=1' error. Define K_RELOAD in util/hist.h. 2. Skip setup_sorting() in repeat path if last key is K_RELOAD. v4: --- Need to quit in perf_evsel_menu__run if key is K_RELOAD.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
