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 <oomichi@mxs.nes.nec.co.jp> Acked-by: Simon Horman <horms@verge.net.au> Cc: David Rientjes <rientjes@google.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
