Subject: [PATCH -next] ftrace: Make ftrace_profile_pages_init() static

The sparse tool complains as follows:

kernel/trace/ftrace.c:587:5: warning:
 symbol 'ftrace_profile_pages_init' was not declared. Should it be static?

ftrace_profile_pages_init() is not used out of ftrace.c, so
marks it static.
