Nothing looked particularly suspicious, but I've found that I've missed the definition of pfn_to_nid() is for DISCONTIGMEM only, maybe making it available for SPARSE would help :) I'm pretty much shooting in the dark here, but can you please try the patch below on top of the original one: diff --git a/arch/mips/include/asm/mmzone.h b/arch/mips/include/asm/mmzone.h index b826b84..273290e 100644 --- a/arch/mips/include/asm/mmzone.h +++ b/arch/mips/include/asm/mmzone.h @@ -20,10 +20,10 @@ #define nid_to_addrbase(nid) 0 #endif -#ifdef CONFIG_DISCONTIGMEM +/* #ifdef CONFIG_DISCONTIGMEM */ #define pfn_to_nid(pfn) pa_to_nid((pfn) << PAGE_SHIFT) -#endif /* CONFIG_DISCONTIGMEM */ +/* #endif /\* CONFIG_DISCONTIGMEM *\/ */ #endif /* _ASM_MMZONE_H_ */ > Linux version 5.3.0-rc5-01209-gad9238e45ea0-dirty (tbogendoerfer@samweis) > (gcc version 6.1.1 20160621 (Red Hat Cross 6.1.1-2) (GCC)) #759 SMP Thu Sep 5 > 15:04:55 CEST 2019 > ARCH: SGI-IP27 > PROMLIB: ARC firmware Version 64 Revision 0 > Discovered 8 cpus on 4 nodes > ************** Topology ******************** > 00 01 02 03 > 00 0 1 2 2 > 01 1 0 2 2 > 02 2 2 0 1 > 03 2 2 1 0 > Router 0: r 1 0 r > Router 1: r 3 2 r > printk: bootconsole [early0] enabled > CPU0 revision is: 00000e23 (R12000) > FPU revision is: 00000900 > Checking for the multiply/shift bug... no. > Checking for the daddiu bug... no. > IP27: Running on node 0. > Node 0 has a primary CPU, CPU is running. > Node 0 has a secondary CPU, CPU is running. > Machine is in M mode. > Determined physical RAM map: > memory: 00000000006ec000 @ 000000000001c000 (usable) > memory: 0000000000058000 @ 0000000000708000 (usable after init) > memory: 000000000002f000 @ 0000000000760000 (usable) > sparse init > REPLICATION: ON nasid 0, ktext from nasid 0, kdata from nasid 0 > REPLICATION: ON nasid 1, ktext from nasid 0, kdata from nasid 0 > REPLICATION: ON nasid 2, ktext from nasid 0, kdata from nasid 0 > REPLICATION: ON nasid 3, ktext from nasid 0, kdata from nasid 0 > Primary instruction cache 32kB, VIPT, 2-way, linesize 64 bytes. > Primary data cache 32kB, 2-way, VIPT, no aliases, linesize 32 bytes > Unified secondary cache 8192kB 2-way, linesize 128 bytes. > Zone ranges: > Normal [mem 0x0000000000000000-0x000000035bffffff] > Movable zone start for each node > Early memory node ranges > node 0: [mem 0x0000000000000000-0x0000000023ffffff] > node 0: [mem 0x0000000028000000-0x000000002bffffff] > node 0: [mem 0x0000000030000000-0x0000000033ffffff] > node 0: [mem 0x0000000038000000-0x000000003bffffff] > node 1: [mem 0x0000000100000000-0x0000000123ffffff] > node 1: [mem 0x0000000128000000-0x000000012bffffff] > node 1: [mem 0x0000000130000000-0x0000000133ffffff] > node 1: [mem 0x0000000138000000-0x000000013bffffff] > node 2: [mem 0x0000000200000000-0x0000000203ffffff] > node 2: [mem 0x0000000208000000-0x000000020bffffff] > node 2: [mem 0x0000000210000000-0x0000000213ffffff] > node 2: [mem 0x0000000218000000-0x000000021bffffff] > node 2: [mem 0x0000000220000000-0x0000000223ffffff] > node 2: [mem 0x0000000228000000-0x000000022bffffff] > node 2: [mem 0x0000000230000000-0x0000000233ffffff] > node 2: [mem 0x0000000238000000-0x000000023bffffff] > node 3: [mem 0x0000000300000000-0x0000000303ffffff] > node 3: [mem 0x0000000308000000-0x000000030bffffff] > node 3: [mem 0x0000000310000000-0x0000000313ffffff] > node 3: [mem 0x0000000318000000-0x000000031bffffff] > node 3: [mem 0x0000000320000000-0x0000000323ffffff] > node 3: [mem 0x0000000328000000-0x000000032bffffff] > node 3: [mem 0x0000000330000000-0x0000000333ffffff] > node 3: [mem 0x0000000338000000-0x000000033bffffff] > node 3: [mem 0x0000000340000000-0x0000000343ffffff] > node 3: [mem 0x0000000348000000-0x000000034bffffff] > node 3: [mem 0x0000000350000000-0x0000000353ffffff] > node 3: [mem 0x0000000358000000-0x000000035bffffff] > Zeroed struct page in unavailable ranges: 442368 pages > Initmem setup node 0 [mem 0x0000000000000000-0x000000003bffffff] > Initmem setup node 1 [mem 0x0000000100000000-0x000000013bffffff] > Initmem setup node 2 [mem 0x0000000200000000-0x000000023bffffff] > Initmem setup node 3 [mem 0x0000000300000000-0x000000035bffffff] > percpu: Embedded 19 pages/cpu s39584 r8192 d30048 u77824 > CPU 0 clock is 300MHz. > Built 4 zonelists, mobility grouping on.
