From: "Steven Rostedt (Google)" <rostedt@goodmis.org>

A new "shutdown" timer state is being added to the generic timer code. One
of the functions to change the timer into the state is called
"timer_shutdown()". This means that there can not be other functions called
"timer_shutdown()" as the timer code owns the "timer_*" name space.

Rename timer_shutdown() to spear_timer_shutdown() to avoid this conflict.
