From ab4627683a0e4430cb5acb1cd896f08ec5dad90c Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Mon, 23 Apr 2007 14:47:59 +0100 Subject: [PATCH] [POWERPC] pci_32.c: Switch to ref counting PCI API pci_find_slot isn't hot-plug safe. Move this code to the pci hotplug safe equivalent and hold a refcount properly while doing make_one_node_map.
