[PATCH v1 00/13] tools/x86/kcpuid: Update to x86-cpuid-db v2.0

[Ahmed S. Darwish]

Hi,

This series updates kcpuid's bitfields CSV file to version v2.0, as
generated by the x86-cpuid-db project.

Version 2.0 of the CSV file introduces new bitfields for leaves 0x7 and
0x0x80000001.  It also introduces new leaves for Transmeta (0x3,
0x80860000 => 0x80860007) and Centaur/Zhaoxin (0xc0000000 => 0xc0000001).

Summary:

* Patch 1 fixes spdxcheck failures by adding CC0-1.0 to LICENSES/.

* Patch 3 is a generic kcpuid error handling bugfix, with patch 2 as its
  prepraration.  Thanks to Remington Brasga for the bug report.

* Patches 4-6 are preparatory kcpuid cleanups.

* Patches 7-11 introduces rudimentary x86 vendor detection and filtering
  to kcpuid, as the CSV file will be updated with indices that are
  exclusive to certain vendors.

* Patch 12 updates the CSV file to x86-cpuid-db v2.0.

* Patch 13 puts the whole kcpuid tool under MAINTAINERS' X86 CPUID entry
  since changes to the bitfields CSV may require updates to the kcpuid
  code (as in this patch queue).  I would also like to have both myself
  and the x86-cpuid mailing list CCed for future kcpuid patches.
