FUJITA Tomonori 4a0d3f3afd parisc: fix IOMMU's device boundary overflow bug on 32bits arch
On 32bits boxes, boundary_size becomes zero due to a overflow and we
hit BUG_ON in iommu_is_span_boundary.

/*
** HP VISUALIZE Workstation PCI Bus Defect
**
** "HP has discovered a potential system defect that can affect
** the behavior of five models of HP VISUALIZE workstations when
** equipped with third-party or customer-installed PCI I/O expansion
** cards. The defect is limited to the HP C180, C160, C160L, B160L,
** and B132L VISUALIZE workstations, and will only be encountered
** when data is transmitted through PCI I/O expansion cards on the
** PCI bus. HP-supplied graphics cards that utilize the PCI bus are
** not affected."

** REVISIT: "go/pci_defect" link below is stale.

**	Product		First Good Serial Number
**  C200/C240 (US)	US67350000

**   C200 (Europe)	3713G01000

** Note that many boards were fixed/replaced under a free replacement
** program. Assume a machine is only "suspect" until proven otherwise.
