Adrian Hunter 26f19c2eb7 perf intel-pt: Fix itrace defaults for perf script 
Commit 4eb0681571 ("perf script: Make itrace script default to all
calls") does not work because 'use_browser' is being used to determine
whether to default to periodic sampling (i.e. better for perf report).
The result is that nothing but CBR events display for perf script when
no --itrace option is specified.

Fix by using 'default_no_sample' and 'inject' instead.

Example:

 Before:

  $ perf record -e intel_pt/cyc/u ls
  $ perf script > cmp1.txt
  $ perf script --itrace=cepwx > cmp2.txt
  $ diff -sq cmp1.txt cmp2.txt
  Files cmp1.txt and cmp2.txt differ

 After:

  $ perf script > cmp1.txt
  $ perf script --itrace=cepwx > cmp2.txt
  $ diff -sq cmp1.txt cmp2.txt
  Files cmp1.txt and cmp2.txt are identical

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.
