Subject: mm/page_alloc: make zone_pcp_update() static
Date: Fri, 16 Sep 2022 15:22:43 +0800
Since commit b92ca18e8ca5 ("mm/page_alloc: disassociate the pcp->high from
pcp->batch"), zone_pcp_update() is only used in mm/page_alloc.c. Move
zone_pcp_update() up to avoid forward declaration and then make it static.
No functional change intended.
