James Clark c36c1ef6f6 perf cs-etm: Start reading 'Z' --itrace option
Recently the 'Z' --itrace option was added to override detection
of timeless decoding. This is also useful in Coresight to work around
issues with invalid timestamps on some hardware.

When the 'Z' option is provided, the existing timeless decoding mode
will be used, even if timestamps were recorded.

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.
