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
