From 8c2676a5870ab15cbeea9f826266bc946fe3cc26 Mon Sep 17 00:00:00 2001 From: Keith Mannthey Date: Sat, 30 Sep 2006 23:27:07 -0700 Subject: [PATCH] hot-add-mem x86_64: memory_add_physaddr_to_nid node fixup In cases where the acpi memory-add event does not containe the pxm (node) infomation allow the driver to look up node info based on the address. The acpi_get_node call returns -1 if it can't decode the pxm info, this causes add_memory to panic. acpi_get_node would have to decode the resource from the handle (a lenghty proposition). This seems to be the cleanist point to interject the hook.
