[PATCH v2 0/4] Fixing SMP config for DeviceTree platforms

[Saurabh Sengar <ssengar@linux.microsoft.com>]

Original motivation for these changes was to fix an SMT warning observed
in Hyper-V VTL platform. Check V1 for more details:
https://lore.kernel.org/lkml/1710265404-23146-1-git-send-email-ssengar@linux.microsoft.com/

But on further review it was observed that x86 DeviceTree config has
modified recently, and there is opportunity to improve the existing
smp parsing for DeviceTree.

Changes are small but I have logically separated them into four patches.
I am willing to merge them if there are too many 

[V2]
- Modified the approch how to fix the SMT issue, this is patch 3
  in this series. V1 for it is mentioned in above link.
- Added 2 more patches which are related to new SMP config parsing.
  These are patches 2 and 4 in this series.
- Fixed an issue with hv_vtl platform how it should use the smp
  parsing for DeviceTree with a fixes tag.

Saurabh Sengar (4):
  x86/hyperv/vtl: Correct parse_smp_cfg assignment
  x86/of: Set the parse_smp_cfg for all the DeviceTree platforms by
    default
  x86/of: Map NUMA node to CPUs as per DeviceTree
  x86/of: Change x86_dtb_parse_smp_config to static
