ata_piix: fix suspend/resume for some TOSHIBA laptops
ACPI implementations in several TOSHIBA laptops are weird and burn cpu
cycles for tens of seconds while trying to suspend if the PCI device
for the ATA controller is disabled when the ACPI suspend is called.
This patch uses DMI to match those machines and bypass device disable
on those machines during suspend. As the device needs to be put into
enabled state on resume without affecting PCI enable count, matching
resume callback uses __pci_reenable_device().

uml: fix string exporting on UML/i386
In 2.6.23-rc1, i386 fiddled its string support such that UML started getting
undefined references from modules. The UML asm/string.h was including the
i386 string.h, which defined __HAVE_ARCH_STR*, but the corresponding
implementations weren't being pulled in.
This is fixed by adding arch/i386/lib/string.h to the list of host
architecture files to be pulled in to UML.
A complication is that the libc exports file assumed that the generic strlen
and strstr weren't in use (i.e. __HAVE_ARCH_STR is defined), then they aren't
exported. This is untrue for strlen, which is exported in either case, so
this logic is not needed.

fallocate syscall interface deficiency
The fallocate syscall returns ENOSYS in case the filesystem does not support
the operation and expects the userlevel code to fill in. This is good in
concept.
The problem is that the libc code for old kernels should be able to
distinguish the case where the syscall is not at all available vs not
functioning for a specific mount point. As is this is not possible and we
always have to invoke the syscall even if the kernel doesn't support it.

[POWERPC] Make endianess of cfg_addr for indirect pci ops runtime
Make it so we do a runtime check to know if we need to write cfg_addr
as big or little endian. This is needed if we want to allow 86xx support
to co-exist in the same kernel as other 6xx PPCs.

[POWERPC] Removed setup_indirect_pci_nomap
We don't use setup_indirect_pci_nomap in arch/powerpc and it appears
the users that needed it from arch/ppc are now using setup_indirect_pci.

[POWERPC] 85xx: Add quirk to ignore bogus FPGA on CDS
The newer Arcadia boards for CDS have an FPGA that shows up on PCI
however isn't a real PCI device. Add a quirk to just ignore the
FPGA.
This is based on the following patch from Andy & York:

[POWERPC] Fixup resources on pci_bus for PCIe PHB when no device is connected
On the 85xx/86xx PCIe controllers if there is no device connected to the
PHB we will still allocate a pci_bus for downstream bus of the virtual
P2P bridge. However the resources allocated to the downstream bus are not
correct and so we just mimic the resources from the upstream pci_bus.
