Changbin Du 69c5f3ca16 perf: script: add raw|disasm arguments to --insn-trace option
[ Upstream commit 6750ba4b6442fa5ea4bf5c0e4b4ff8b0249ef71d ]

Now '--insn-trace' accept a argument to specify the output format:
  - raw: display raw instructions.
  - disasm: display mnemonic instructions (if capstone is installed).

$ sudo perf script --insn-trace=raw

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.
