xtensa/PCI: convert to pci_scan_root_bus() for correct root bus resources
x86/PCI: convert to pci_create_root_bus() and pci_scan_root_bus()
x86/PCI: use pci_scan_bus() instead of pci_scan_bus_parented()
x86/PCI: read Broadcom CNB20LE host bridge info before PCI scan
sparc32, leon/PCI: convert to pci_scan_root_bus() for correct root bus resources

powerpc/PCI: split PHB part out of pcibios_map_io_space()
...Fix up conflicts in drivers/pci/msi.c and include/linux/pci_regs.h due
to the same patches being applied in other branches.

During S3 or S4 resume or PCI reset, ATS regs aren't restored correctly.
This patch enables ATS at the device state restore if PCI device has ATS
capability.Signed-off-by: Xudong Hao

I get this compile failure on parisc:
drivers/pci/ats.c: In function 'ats_alloc_one':
drivers/pci/ats.c:29: error: implicit declaration of function 'kzalloc'
drivers/pci/ats.c:29: warning: assignment makes pointer from integer without a cast
drivers/pci/ats.c: In function 'ats_free_one':
drivers/pci/ats.c:45: error: implicit declaration of function 'kfree'Because ats.c is missing linux/slab.h as an include. This patch fixes it

More consistency cleanups. Drop the _OFF, separate and indent
CTRL/CAP/STATUS bit definitions. This helped find the previous
mis-use of bit 0 in the PASID capability register.Reviewed-by: Joerg Roedel

The PASID ECN indicates bit 0 is reserved in the capability register.
Switch pci_enable_pasid() to error if PASID is already enabled and
don't expose enable as a feature in pci_pasid_features().Reviewed-by: Joerg Roedel

They were implicitly getting it from device.h --> module.h but
we want to clean that up. So add the minimal header for these
macros.Signed-off-by: Paul Gortmaker

Devices supporting Process Address Space Identifiers
(PASIDs) can use an IOMMU to access multiple IO address
spaces at the same time. A PCIe device indicates support for
this feature by implementing the PASID capability. This
patch adds support for the capability to the Linux kernel.Reviewed-by: Bjorn Helgaas

Implement the necessary functions to handle PRI capabilities
on PCIe devices. With PRI devices behind an IOMMU can signal
page fault conditions to software and recover from such
faults.Reviewed-by: Bjorn Helgaas

This patch makes the ATS functions usable for modules.
They will be used by a module implementing some advanced
AMD IOMMU features.Reviewed-by: Bjorn Helgaas

ATS does not depend on IOV support, so move the code into
its own file. This file will also include support for the
PRI and PASID capabilities later.
Also give ATS its own Kconfig variable to allow selecting it
without IOV support.Reviewed-by: Bjorn Helgaas
