(noted by Dennis Chen and Hanjun Guo) - New patch 7/14 to print different messages for NUMA disabled case. (noted by Dennis Chen) - Squashed two patches into 14/14. - Added Reviewed-by to 4/14 v5 updates: - Fixed ia64 build failure by gating some unused functions with #if CONFIG_{X86,ARM64}. - Fixed section mismatch errors for X86 case. - Removed unneeded #include from some files. - Tested to build cleanly on ARM64, X86_64, IA64 v4 updates: - Updated from Hanjun Guo's v3 patches. - Rebased on top of v16 of device-tree NUMA patches. - Reordered some of the changes so that we don't introduce code and then change it several times in the patch set. New code is introduced in its final form. Code reused from x86 is first moved with no change, and then a separate patch to make any needed changes. - code that is used only by ia64, moved to architecture specific files. v3 updates: - Deep investigation about the ACPI_DEBUG_PRINT() and remvoe that for acpi/numa.c (patch 2/12) - Remove the duplicate NULL check for table print (patch 3/12) - Introduce CONFIG_ACPI_HAS_NUMA_ARCH_FIXUP to remove duplicate dummy function for acpi_numa_arch_fixup() - Solve the problem that the mapping from logical cpu to numa node is wrong which spotted out by Lorenzo - cleanups for x86 and move acpi_numa_slit_init() and some other functions to common place, then reduce the duplicate of x86 and arm64 (patch 7-12/12). - rebased on top of 4.4 and Ganapat's v9 patch set.
