From: "Ken'ichi Ohmichi" This patch fixes the configuration dependencies in the vmcoreinfo data. i386's "node_data" is defined in arch/x86/mm/discontig_32.c, and x86_64's one is defined in arch/x86/mm/numa_64.c. They depend on CONFIG_NUMA: arch/x86/mm/Makefile_32:7 obj-$(CONFIG_NUMA) += discontig_32.o arch/x86/mm/Makefile_64:7 obj-$(CONFIG_NUMA) += numa_64.o ia64's "pgdat_list" is defined in arch/ia64/mm/discontig.c, and it depends on CONFIG_DISCONTIGMEM and CONFIG_SPARSEMEM: arch/ia64/mm/Makefile:9-10 obj-$(CONFIG_DISCONTIGMEM) += discontig.o obj-$(CONFIG_SPARSEMEM) += discontig.o ia64's "node_memblk" is defined in arch/ia64/mm/numa.c, and it depends on CONFIG_NUMA: arch/ia64/mm/Makefile:8 obj-$(CONFIG_NUMA) += numa.o Signed-off-by: Ken'ichi Ohmichi Acked-by: Simon Horman Cc: David Rientjes Signed-off-by: Andrew Morton --- arch/ia64/kernel/machine_kexec.c | 5 +++-- arch/x86/kernel/machine_kexec_32.c | 2 +- 2 files changed, 4 insertions(+), 3 deletions(-) diff -puN arch/ia64/kernel/machine_kexec.c~vmcoreinfo-fix-the-configuration-dependencies arch/ia64/kernel/machine_kexec.c --- a/arch/ia64/kernel/machine_kexec.c~vmcoreinfo-fix-the-configuration-dependencies +++ a/arch/ia64/kernel/machine_kexec.c @@ -129,10 +129,11 @@ void machine_kexec(struct kimage *image) void arch_crash_save_vmcoreinfo(void) { -#if defined(CONFIG_ARCH_DISCONTIGMEM_ENABLE) && defined(CONFIG_NUMA) +#if defined(CONFIG_DISCONTIGMEM) || defined(CONFIG_SPARSEMEM) VMCOREINFO_SYMBOL(pgdat_list); VMCOREINFO_LENGTH(pgdat_list, MAX_NUMNODES); - +#endif +#ifdef CONFIG_NUMA VMCOREINFO_SYMBOL(node_memblk); VMCOREINFO_LENGTH(node_memblk, NR_NODE_MEMBLKS); VMCOREINFO_STRUCT_SIZE(node_memblk_s); diff -puN arch/x86/kernel/machine_kexec_32.c~vmcoreinfo-fix-the-configuration-dependencies arch/x86/kernel/machine_kexec_32.c --- a/arch/x86/kernel/machine_kexec_32.c~vmcoreinfo-fix-the-configuration-dependencies +++ a/arch/x86/kernel/machine_kexec_32.c @@ -151,7 +151,7 @@ NORET_TYPE void machine_kexec(struct kim void arch_crash_save_vmcoreinfo(void) { -#ifdef CONFIG_ARCH_DISCONTIGMEM_ENABLE +#ifdef CONFIG_NUMA VMCOREINFO_SYMBOL(node_data); VMCOREINFO_LENGTH(node_data, MAX_NUMNODES); #endif _
