Russ Anderson f9228b204f mm: zone_end_pfn is too small ... Booting with 32 TBytes memory hits BUG at mm/page_alloc.c:552! (output below). The key hint is "page 4294967296 outside zone". 4294967296 = 0x100000000 (bit 32 is set). The problem is in include/linux/mmzone.h: 530 static inline unsigned zone_end_pfn(const struct zone *zone) 531 { 532 return zone->zone_start_pfn + zone->spanned_pages; 533 } zone_end_pfn is "unsigned" (32 bits). Changing it to "unsigned long" (64 bits) fixes the problem. zone_end_pfn() was added recently in commit 108bcc96ef ("mm: add & use zone_end_pfn() and zone_spans_pfn()") Output from the failure. No AGP bridge found page 4294967296 outside zone [ 4294967296 - 4327469056 ] ------------[ cut here ]------------ kernel BUG at mm/page_alloc.c:552! invalid opcode: 0000 [#1] SMP Modules linked in: CPU 0 Pid: 0, comm: swapper Not tainted 3.9.0-rc2.dtp+ #10 RIP: free_one_page+0x382/0x430 Process swapper (pid: 0, threadinfo ffffffff81942000, task ffffffff81955420) Call Trace: __free_pages_ok+0x96/0xb0 __free_pages+0x25/0x50 __free_pages_bootmem+0x8a/0x8c __free_memory_core+0xea/0x131 free_low_memory_core_early+0x4a/0x98 free_all_bootmem+0x45/0x47 mem_init+0x7b/0x14c start_kernel+0x216/0x433 x86_64_start_reservations+0x2a/0x2c x86_64_start_kernel+0x144/0x153 Code: 89 f1 ba 01 00 00 00 31 f6 d3 e2 4c 89 ef e8 66 a4 01 00 e9 2c fe ff ff 0f 0b eb fe 0f 0b 66 66 2e 0f 1f 84 00 00 00 00 00 eb f3 <0f> 0b eb fe 0f 0b 0f 1f 84 00 00 00 00 00 eb f6 0f 0b eb fe 49 Signed-off-by: Russ Anderson <rja@sgi.com> Reported-by: George Beshers <gbeshers@sgi.com> Acked-by: Hedi Berriche <hedi@sgi.com> Cc: Cody P Schafer <cody@linux.vnet.ibm.com> Cc: Michal Hocko <mhocko@suse.cz> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2013-03-22 16:41:20 -07:00
