From: Robert Richter
Date: Tue Apr 30 2024 - 05:27:25 EST


Some fixes and updates for SRAT/CEDT parsing code. Patches can be
applied individually and are independent.

First patch fixes a page fault during boot (fix as suggested by Dan).

Patches 2 to 4 remove architectural code no longer needed.

Patches 5 to 7 add diagnostic printouts for CEDT.

Changelog:

v6:
* rebased onto cxl/fixes
* fixed 0day build errors in patch #1:
https://github.com/intel-lab-lkp/linux/commits/Robert-Richter/x86-numa-Fix-SRAT-lookup-of-CFMWS-ranges-with-numa_fill_memblks/20240429-205337

v5:
* dropped: "x86/numa: Fix SRAT lookup of CFMWS ranges with
numa_fill_memblks()"
* added: "ACPI/NUMA: Return memblk modification state from
numa_fill_memblks()"
* conditionally print CEDT extended memblks

v4:
* updated SOB chains and desription
* added patch "x86/numa: Remove numa_fill_memblks() from sparsemem.h
using __weak"
* Reordered patches to move CEDT table printout as an option at the
end
* split print table patch and added: "ACPI/NUMA: Add log messages for
memory ranges found in CEDT"

v3:
* Rebased onto v6.9-rc1

* Fixed performance regression introduced [kbot]
* Fixed checkpatch issues [Dan]
