Subject: let __dec_zone_page_state use __dec_zone_state
X-Git-Tag: firefly_0821_release~22244
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=57ce36feb4d1281247755bc445bae77728298955;p=firefly-linux-kernel-4.4.55.git

let __dec_zone_page_state use __dec_zone_state

This removes code duplication and makes __dec_zone_page_state look like
__inc_zone_page_state.
