Adrian Hunter 37c1f991b1 perf scripts python: export-to-sqlite.py: Export switch events
Export switch events to a new table 'context_switches' and create a view
'context_switches_view'. The table and view will show automatically in
the exported-sql-viewer.py script.

If the table ends up empty, then it and the view are dropped.

Committer testing:

Use the exported-sql-viewer.py and look at "Tables" ->
"context_switches":

  id  machine_id  time             cpu  thread_out_id  comm_out_id  thread_in_id  comm_in_id  flags

README

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.
