Subject: [PATCH 0/3] x86: cpu: Add new Airmont CPU model

Intel Atom CPU based Lightning Mountain(LGM) network processor SoC has recently
taped out. Although the Atom CPU used in LGM is based upon Airmont uArch but it
has a few differences. Its a new variant of Atom Airmont cpu model.

This series of patches adds support for this new CPU model.

Patches are baselined upon Linux 5.3-rc4 at below Git tree:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86/core

Patch 1 replaces existing direct values usage with constant definitions when
access CPU models.

Patch 2 adds a constant definition for the new Atom CPU model.

Patch 3 updates capabilities & vulnerabilities applicable for this new CPU model.

Rahul Tanwar (3):
  x86: cpu: Use constant definitions for CPU type
  x86: cpu: Add new Intel Atom CPU type
  x86: arch: Add arch support for new Intel Atom CPU
