Steven Rostedt (VMware) 2db7ab6b4c tracing: Have ftrace_dump_on_oops kernel parameter take numbers
The kernel parameter for ftrace_dump_on_oops can take a single assignment.
That is, it can be:

  ftrace_dump_on_oops or ftrace_dump_on_oops=orig_cpu

But the content in the sysctl file is a number.

 0 for disabled
 1 for ftrace_dump_on_oops (all CPUs)
 2 for ftrace_dump_on_oops (orig CPU)

Allow the kernel command line to take a number as well to match the sysctl
numbers.

That is:

  ftrace_dump_on_oops=1 is the same as ftrace_dump_on_oops

and

  ftrace_dump_on_oops=2 is the same as ftrace_dump_on_oops=orig_cpu

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.
