[PATCH v3 0/3] Fix couple of issues with AMD topology

Subject: [PATCH v3 0/3] Fix couple of issues with AMD topology
Date: Fri, 07 Aug 2020 11:32:38 -0500
User-agent: StGit/unknown-version

This series fixes couple of issues with recent topology related code.
1. Warn users to pass the dies information if EPYC cpu is numa configured.

2. Remove the node_id references in topology and use die_id instead.

3. With node_id removed in topology the uninitialized memory issue 
   with -device and CPU hotplug will be fixed.
   Link: https://bugzilla.redhat.com/show_bug.cgi?id=1828750

  Added a new check to pass the dies for EPYC numa configuration.
  Added Simplify CPUID_8000_001E patch with some changes suggested by Igor.
  Dropped the patch to build the topology from CpuInstanceProperties.
  TODO: Not sure if we still need the Autonuma changes Igor mentioned.
  Needs more clarity on that.

 - Used the numa information from CpuInstanceProperties for building
   the apic_id suggested by Igor.
 - Also did some minor code re-aarangement to take care of changes.
 - Dropped the patch "Simplify CPUID_8000_001E" from v1. Will send
   it later.
