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

Hi all,

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

arch/x86/kernel/cpu/amd.c: In function 'bsp_init_amd':
arch/x86/kernel/cpu/amd.c:545:3: error: '__max_die_per_package' undeclared (first use in this function); did you mean 'topology_max_die_per_package'?
  545 |   __max_die_per_package = nodes_per_socket = ((ecx >> 8) & 7) + 1;
      |   ^~~~~~~~~~~~~~~~~~~~~
      |   topology_max_die_per_package

Caused by commit

  76e2fc63ca40 ("x86/cpu/amd: Set __max_die_per_package on AMD")

I have reverted that commit for today.
Stephen Rothwell
