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
