This series needs to be prepended with the original series[1][2][3]
Except the first patch in the original series(which is merged into this
as last patch), there is no other change(apart from function signature)
I am posting only this part for feedback separately for review as the
original series is already reviewed. Once this part is review and aknowledged
I will combine the complete series and post it.

Hi Rob,

Since the compatible 'ibm,ppc-interrupt-server#s' is one-off and for
historical reasons, if future architectures are adhering to ePAPR,
IMO having a weak definition of arch_of_cpu_get_node as you suggested
could lead to it's misuse in future. So I didn't take that approach.


Sudeep KarkadaNagesha (4):
  microblaze: remove undefined of_get_cpu_node declaration
  openrisc: remove undefined of_get_cpu_node declaration
  powerpc: refactor of_get_cpu_node to support other architectures
  of: move of_get_cpu_node implementation to DT core library
