The patch titled
Subject: mm/page_alloc.c: rework code layout in memmap_init_zone()
has been removed from the -mm tree. Its filename was
mm-page_allocc-rework-code-layout-in-memmap_init_zone.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: mm/page_alloc.c: rework code layout in memmap_init_zone()
This function is getting full of weird tricks to avoid word-wrapping. Use
a goto to eliminate a tab stop then use the new space
