Subject: [PATCH] ftrace: make ftrace_profile_pages_init static

From: chongjiapeng <jiapeng.chong@...ux.alibaba.com>

This symbol is not used outside of ftrace.c, so marks it static.

Fixes the following sparse warning:

kernel/trace/ftrace.c:579:5: warning: symbol 'ftrace_profile_pages_init'
was not declared. Should it be static?

Reported-by: Abaci Robot <abaci@...ux.alibaba.com>
Fixes: cafb168a1c92 ("tracing: make the function profiler per cpu")
