Subject: linux-next: build failure after merge of the edac tree

Hi all,

After merging the edac tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/ras/amd/atl/umc.c: In function 'get_die_id':
drivers/ras/amd/atl/umc.c:318:44: error: implicit declaration of function 'amd_get_nodes_per_socket' [-Werror=implicit-function-declaration]
  318 |         return topology_die_id(err->cpu) % amd_get_nodes_per_socket();
      |                                            ^~~~~~~~~~~~~~~~~~~~~~~~

Caused by commit

  3f3174996be6 ("RAS: Introduce AMD Address Translation Library")

interacting with commit

  c749ce393b8f ("x86/cpu: Use common topology code for AMD")

from the tip tree.

I applied the following merge resolution patch.
