Subject: [PATCH v3 0/5] SRAT/CEDT fixes and updates

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 adds diagnostic printouts for CEDT.

Patches 3 to 5 remove architectural code no longer needed.

Changelog:

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.
