The patch titled
Subject: mm/page_alloc.c: set a zone_start_pfn value in zone_spanned_pages_in_node
has been removed from the -mm tree. Its filename was
mm-calculate-zone_start_pfn-at-zone_spanned_pages_in_node-fix.patch
This patch was dropped because it had testing failures
------------------------------------------------------
From: Arnd Bergmann <arnd@xxxxxxxx>
Subject: mm/page_alloc.c: set a zone_start_pfn value in zone_spanned_pages_in_node
We got a new build warning in linux-next:
mm/page_alloc.c: In function 'free_area_init_node':
mm/page_alloc.c:5278:25: warning: 'zone_start_pfn' may be used uninitialized in this function [-Wmaybe-uninitialized]
zone->zone_start_pfn = zone_start_pfn;
mm/page_alloc.c:5265:17: note: 'zone_start_pfn' was declared here
unsigned long zone_start_pfn, zone_end_pfn;
The code indeed looks wrong, but this is just a guess of what the
fix might be: I have not looked it in detail, so please treat this
as a bug report.
