3891b6acb4 PCI: Stop all children first, before removing all children
This restores the previous behavior of stopping all child devices before
removing any of them.  The current SR-IOV design, where removing the PF
also drops references on all the VFs, depends on having the VFs continue
to exist after having been stopped.

94bb346480 Revert "PCI: Use hotplug-safe pci_get_domain_bus_and_slot()"
This reverts commit 433efd2247.

When we remove an SR-IOV device, we have this call chain:

    driver .remove() method
        pci_disable_sriov()
            sriov_disable()
                virtfn_remove()
                    pci_get_domain_bus_and_slot()

sriov_disable() is only called for PFs, not for VFs.  When it's called
for a PF, it loops through all the VFs and calls virtfn_remove() for
each.  But we stop and remove VFs before PFs, so by the time we get
to virtfn_remove(), the VFs have already been stopped and deleted
from the device list.  Now pci_get_domain_bus_and_slot(), which uses
bus_find_device() and relies on that device list, doesn't find the
VFs, so the VF references aren't released correctly.

3ddbebf878 PCI: Discard __init annotations for pci_fixup_irqs() and related functions
Remove the __init annotations in order to keep pci_fixup_irqs() around
after init (e.g. for hotplug). This requires the same change for the
implementation of pcibios_update_irq() on all architectures. While at
it, all __devinit annotations are removed as well, since they will be
useless now that HOTPLUG is always on.

if PCI hotplug operation happens between them which removes the pci_bus.
So use PCI hotplug safe interface pci_get_domain_bus_and_slot() instead,
which also reduces code complexity.

271fd03a30 powerpc/powernv: I/O and memory alignment for P2P bridges
The patch implements ppc_md.pcibios_window_alignment for powernv
platform so that the resource reassignment in PCI core will be
done according to the I/O and memory alignment returned from
powernv platform. The alignments returned from powernv platform
is closely depending on the scheme for PE segmenting. Besides,
the patch isn't useful for now, but the subsequent patches will
be working based on it.

This patch implements a weak function to return the default I/O or memory

4KiB or 1KiB and memory windows are aligned to 4MiB.  Some platforms, e.g.,
powernv, have special alignment requirements and can override
pcibios_window_alignment().

	 */

But there is no ide_setup() now, and no down_read() either, which
makes the check obsolete. So remove it.

80ba77dfbc xen/pciback: Fix proper FLR steps.
When we do FLR and save PCI config we did it in the wrong order.
The end result was that if a PCI device was unbind from
its driver, then binded to xen-pciback, and then back to its
driver we would get:

> lspci -s 04:00.0
04:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network Connection
13:42:12 # 4 :~/
> echo "0000:04:00.0" > /sys/bus/pci/drivers/pciback/unbind

e1000e: Intel(R) PRO/1000 Network Driver - 2.0.0-k
e1000e: Copyright(c) 1999 - 2012 Intel Corporation.
e1000e 0000:04:00.0: Disabling ASPM L0s L1

xen: registering gsi 48 triggering 0 polarity 1

e1000e: probe of 0000:04:00.0 failed with error -2

This fixes it by first saving the PCI configuration space, then
doing the FLR.
