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.
