Subject: [PATCH v2 1/1] mm: page_alloc: Avoid defining unused function

In some configurations I got
mm/page_alloc.c:656:20: warning: unused function 'add_to_free_list' [-Wunused-function]
Becuase the only user is guarged with a certain ifdeffery,
do the same for add_to_free_list().

Signed-off-by: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>
---
v2: moved the function down to the respective ifdeffery block (Liam)
