Subject: fix kmalloc(0) in arch/ia64/pci/pci.c
From: Kenji Kaneshige <[EMAIL PROTECTED]>
Hiroyuki Kamezawa reported the problem that pci_acpi_scan_root() of
ia64 might call kmalloc_node() with zero size.
Currently ia64's pci_acpi_scan_root() assumes that _CRS method of root
bridge has at least one resource window. But, the root bridges that
has no resource window must be taken into account.
