Commit c0f4dfd4f9 ("rcu: Make RCU_FAST_NO_HZ take advantage of
numbered callbacks") removed the only instances of trace_rcu_prep_idle,
but did not remove the TRACE_EVENT() that creates it. As defined trace
events take up memory within the kernel even when they are not used,
this is a waste of space. Remove the obsolete event.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
