From cd5b50be8d8e8e6170da3a261fc625fd603f9dc4 Mon Sep 17 00:00:00 2001 From: "linas@austin.ibm.com" Date: Thu, 1 Dec 2005 18:59:58 -0600 Subject: [PATCH] [PATCH] PCI Hotplug/powerpc: more removal of duplicated code The RPAPHP code contains two routines that appear to be gratuitous copies of very similar pci code. In particular, rpaphp_claim_resource ~~ pci_claim_resource (there is a minor, non-functional difference) rpadlpar_claim_one_bus == pcibios_claim_one_bus (the code is identical) This patch removes the rpaphp versions of the code.
