Just fold this patch into patch 1/6. Moreover, I think that patches 1-4 can be merged into one. -- Sincerely yours, Mike.

[PATCH v3 4/6] mm: don't export memory_add_physaddr_to_nid in arch specific directory
After a general version of __weak memory_add_physaddr_to_nid implemented and exported , it is no use exporting twice in arch directory even if e,g, ia64/x86 have their specific version. This is to suppress the modpost warning: WARNING: modpost: vmlinux: 'memory_add_physaddr_to_nid' exported twice. Previous export was in vmlinux Suggested-by: David Hildenbrand Signed-off-by: Jia He --- arch/ia64/mm/numa.c | 2 -- arch/x86/mm/numa.c | 1 - 2 files changed, 3 deletions(-) diff --git a/arch/ia64/mm/numa.c b/arch/ia64/mm/numa.c index 5e1015eb6d0d..f34964271101 100644 --- a/arch/ia64/mm/numa.c +++ b/arch/ia64/mm/numa.c @@ -106,7 +106,5 @@ int memory_add_physaddr_to_nid(u64 addr) return 0; return nid; } - -EXPORT_SYMBOL_GPL(memory_add_physaddr_to_nid); #endif #endif diff --git a/arch/x86/mm/numa.c b/arch/x86/mm/numa.c index 8ee952038c80..2a6e62af4636 100644 --- a/arch/x86/mm/numa.c +++ b/arch/x86/mm/numa.c @@ -929,5 +929,4 @@ int memory_add_physaddr_to_nid(u64 start) nid = numa_meminfo.blk[0].nid; return nid; } -EXPORT_SYMBOL_GPL(memory_add_physaddr_to_nid); #endif -- 2.17.1
