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. It should be marked
stable.

2nd patch reworks the code around numa_fill_memblks() (Dan's
suggestion).

Patches 3 to 5 remove architectural code no longer needed.

Patches 6 to 7 add diagnostic printouts for CEDT (can be dropped if
so).

Changelog:

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

v3:
 * Rebased onto v6.9-rc1
 * Fixing x86 build error in sparsemem.h [Dan/Alison]
 * Added CEDT node info [Alison]
 * Use pr_debug() for table output [Dan]
 * Refactoring split in 3 patches [Dan]
 * Fixed performance regression introduced [kbot]
 * Fixed checkpatch issues [Dan]

Bases on v6.9-rc1.

Just squash these 2 together. The -stable maintainers continue to assert
that fixes should do the right thing by mainline mainline standards and
let the -stable backport process decide if a different change needs to
be made for older kernels. I see no benefit for tracking 2 changes for
how numa_fill_memblks() is defined.

Ok, will drop #1 in a v5.

Thanks,
