From 1d89b30cc9be41af87881682ec82e2c107849dbe Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Wed, 17 Jun 2009 16:33:36 -0400 Subject: [PATCH] ia64: Fix resource assignment for root busses ia64 was assigning resources to root busses after allocations had been made for child busses. Calling pcibios_setup_root_windows() from pcibios_fixup_bus() solves this problem by assigning the resources to the root bus before child busses are scanned.
