[PATCH 00/11] Remove the parent_node() for each arch

[PATCH 00/11] Remove the parent_node() for each arch

[Dou Liyang]

Michael reports the parent_node() will never be invoked since the
Commit a7be6e5a7f8d ("mm: drop useless local parameters of
__register_one_node()") removes the last user of it. 

So we start removing it from the topology.h headers for each arch.

Dou Liyang (11):
  arm64: numa: Remove the unused parent_node() macro
  ia64: topology: Remove the unused parent_node() macro
  metag/numa: Remove the unused parent_node() macro
  MIPS: numa: Remove the unused parent_node() macro
  powerpc/numa: Remove the unused parent_node() macro
  s390/topology: Remove the unused parent_node() macro
  sh/numa: Remove the unused parent_node() macro
  sparc64/topology: Remove the unused parent_node() macro
  tile/topology: Remove the unused parent_node() macro
  x86/topology: Remove the unused parent_node() macro
  asm-generic: numa: Remove the unused parent_node() macro
