[PATCH v2 09/27] ftrace: Allow ftrace startup flags to exist without dynamic ftrace

[Steven Rostedt]

From: "Steven Rostedt (VMware)" <rostedt@xxxxxxxxxxx>

Some of the flags for ftrace_startup() may be exposed even when
CONFIG_DYNAMIC_FTRACE is not configured in. This is fine as the difference
between dynamic ftrace and static ftrace is done within the internals of
ftrace itself. No need to have use cases fail to compile because dynamic
ftrace is disabled.

This change is needed to move some of the logic of what is passed to
ftrace_startup() out of the parameters of ftrace_startup().
