When parsing the memory affinity mappings in arch/x86/mm/srat.c: acpi_numa_memory_affinity_init() I'm wondering if the hot-pluggable check is too harsh, as we consider an error if the hot-pluggable bit is set and CONFIG_MEMORY_HOTPLUG is not.
Based on the ACPI specs (v5):
"If the Enabled bit is set and the Hot Pluggable bit is also set. The system hardware supports hot-add and hot-remove of this memory region."
This only mentions that the system supports hot-plugging, and IMHO if the user decides not to use CONFIG_MEMORY_HOTPLUG, it shouldn't be considered an error. Therefore would it be ok to drop the check? Or am I missing something?
Thanks, Davidlohr
