From 92df5c3e38c0a0a66a456926039548275dfb3328 Mon Sep 17 00:00:00 2001 From: Ken'ichi Ohmichi Date: Thu, 7 Feb 2008 00:15:23 -0800 Subject: [PATCH] vmcoreinfo: fix the configuration dependencies 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 Signed-off-by: Linus Torvalds --- arch/ia64/kernel/machine_kexec.c | 5 +++-- arch/x86/kernel/machine_kexec_32.c | 2 +- arch/x86/kernel/machine_kexec_64.c | 5 +++++ 3 files changed, 9 insertions(+), 3 deletions(-) diff --git a/arch/ia64/kernel/machine_kexec.c b/arch/ia64/kernel/machine_kexec.c index 6e725eff271..0823de1f6eb 100644 --- a/arch/ia64/kernel/machine_kexec.c +++ b/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 --git a/arch/x86/kernel/machine_kexec_32.c b/arch/x86/kernel/machine_kexec_32.c index c1cfd60639d..d0b234c9fc3 100644 --- a/arch/x86/kernel/machine_kexec_32.c +++ b/arch/x86/kernel/machine_kexec_32.c @@ -151,7 +151,7 @@ NORET_TYPE void machine_kexec(struct kimage *image) 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 diff --git a/arch/x86/kernel/machine_kexec_64.c b/arch/x86/kernel/machine_kexec_64.c index a1fef42f8cd..236d2f8f7dd 100644 --- a/arch/x86/kernel/machine_kexec_64.c +++ b/arch/x86/kernel/machine_kexec_64.c @@ -234,5 +234,10 @@ NORET_TYPE void machine_kexec(struct kimage *image) void arch_crash_save_vmcoreinfo(void) { VMCOREINFO_SYMBOL(init_level4_pgt); + +#ifdef CONFIG_NUMA + VMCOREINFO_SYMBOL(node_data); + VMCOREINFO_LENGTH(node_data, MAX_NUMNODES); +#endif } -- 2.41.0
