I updated this to remove unnecessary variable initialization, make
check_routing be inline only and not __init, switch to strtoul, and
formatting fixes as per Randy Dunlap's recommendations.
I updated this to change pirq_table_addr to a long, and to add a warning
msg if the PIRQ table wasn't found at the specified address, as per thread
with Matthew Wilcox.
In our hardware situation, the BIOS is unable to store or generate it's PIRQ
table in the F0000h-100000h standard range. This patch adds a pci kernel
parameter, pirqaddr to allow the bootloader (or BIOS based loader) to inform
the kernel where the PIRQ table got stored. A beneficial side-effect is that,
if one's BIOS uses a static address each time for it's PIRQ table, then
pirqaddr can be used to avoid the $pirq search through that address block each
time at boot for normal PIRQ BIOSes.

This patch lengthens the delay between DET setting and clearing for
COMMRESET from 400us to 1ms. I couldn't find any requiremen regarding
the duration of COMMRESET in SATA I/II specs but AHCI-1.1 10.4.2
states that it should be at least 1ms.

The amd8111e driver directly assigns the DMA mask to the dma_mask
member of the struct pci_dev instead of using pci_set_dma_mask(). This
makes the call to pci_dma_supported() redundant as pci_set_dma_mask()
does this check.
I do not own this device so I only compile-tested this patch.

For boards that invert the SMC91x IRQ line (maybe an FPGA inverts it),
the set_irq_type() call can't assume IRQT_RISING. These particular
boards currently use OMAP-specific calls to change the trigger type,
but the boards break when set_irq_type() stops being a NOP.

Don't auto-configure yenta sockets for PCMCIA devices if it is connected to
the root PCI bus on the x86 or x86_64 architectures. Previously, this was
handled by the "ioport_resource"/"iomem_resource" check a few lines below,
but with the new ACPI-based resource handling this doesn't catch all cases
any longer.
pci-yenta-cardbus-fix.patch and this patch should solve the initialization
time trouble. However, the ACPI-based PCI resource handling is badly
broken, IMHO:
- many resources of devices don't show up in the resource trees (
/proc/iomem and /proc/ioports) any longer. This means that PCMCIA, but
also possibly other subsystems (ISA, PnP, ...) do not know which resources
it cannot use.
- verify_root_windows() should fail if there are no iomem _or_ ioport
resources, not only if there are no iomem _and_ ioport resources.

The PCMCIA card services layer is never setting the i/o map attributes when
SS_CAP_STATIC_MAP is specified. Net result, sockets' set_io_map() calls
always see requests with most flags clear, meaning 8 bit access.
For hardware that always autosizes, that won't matter; and all current
STATIC_MAP drivers ignore those attributes. A new driver (for at91rm9200)
suffers badly from this, since this forces everything into 8 bit mode and
that breaks both (a) cards requiring 16 bit access, and (b) ide-cs; but of
course 8-bit cards work OK (as does accessing card attributes).
So this patch arranges to pass the attributes down, matching the behavior
for non-static mappings (using the first/only I/O window).
