[PATCH v5 00/10] Introduce In Field Scan driver

[Tony Luck]

Hopefully this is close enough to done to begin discussion on which
maintainer tree will take this series.

Choices:
1) Hans/Mark take it into the platform-drivers tree
   Needs an Ack from x86 maintainers on parts 1 & 2
2) X86 maintainers take it into TIP
   Needs Ack from Hans/Mark on parts 2-10

TL;DR this driver loads scan test files that can check whether silicon
in a CPU core is still running correctly. It is expected that these tests
would be run several times per day to catch problems as silicon ages.

Changes since v4:

Greg Kroah-Hartman
------------------
 "Cute way to do this, but I don't see you ever have any more devices
 added to this list in this series."

 Removed the enum, arrays, loops, and count of test types discovered.
 Now just check for enumeration of the single test type that is being
 deployed on Sapphire Rapids.
