Subject: [PATCH] mm: remove the exporting of totalram_pages

Previously totalram_pages was the global variable. Currently,
totalram_pages is the static inline function from the include/linux/mm.h
However, the function is also marked as EXPORT_SYMBOL, which is at best
an odd combination. Because there is no point for the static inline
function from a public header to be exported, this commit removes the
EXPORT_SYMBOL() marking. It will be still possible to use the function in
modules because all the symbols it depends on are exported.

Fixes: ca79b0c211af6 ("mm: convert totalram_pages and totalhigh_pages variables to atomic")
