The patch titled
Subject: mm/page_alloc.c: remove zone_type argument of build_zonelists_node
has been removed from the -mm tree. Its filename was
mm-remove-zone_type-argument-of-build_zonelists_node.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Zhang Yanfei <zhangyanfei@xxxxxxxxxxxxxx>
Subject: mm/page_alloc.c: remove zone_type argument of build_zonelists_node
The callers of build_zonelists_node always pass MAX_NR_ZONES -1 as the
zone_type argument, so we can directly use the value in
build_zonelists_node and remove zone_type argument.
