One regression fix for SR-IOV on PPC and a couple of misc fixes from
Yinghai.

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci:
  PCI: Fix pci cardbus removal
  PCI: set pci sriov page size before reading SRIOV BAR
  PCI: workaround hard-wired bus number V2

Two fixes for VCPU offlining; One to fix the string format exposed
by the xen-pci[front|back] to conform to the one used in majority of
PCI drivers; Two fixes to make the code more resilient to invalid
configurations.

During test busn_res allocation with cardbus, found pci card removal is not
working anymore, and it turns out it is broken by:

|    PCI: Only call pci_stop_bus_device() one time for child devices at remove

The above changed the behavior of pci_remove_behind_bridge that
yenta_cardbus depended on.  So restore the old behavoir of
pci_remove_behind_bridge (which requires stopping and removing of all
devices) by:

1. rename pci_remove_behind_bridge to __pci_remove_behind_bridge, and let
   __pci_remove_bus_device() call it instead.
2. add pci_stop_behind_bridge that will stop devices behind a bridge
3. add back pci_remove_behind_bridge that will stop and remove devices
   under bridge.

-v2: update commit description a little bit.

For an SRIOV device, PCI_SRIOV_SYS_PGSIZE should be set before
the PCI_SRIOV_BAR are queried.  The sys pagesize defaults to 4k,
so this change is required on powerpc box with 64k base page size.
    
This is a regression caused due to moving SRIOV init to sriov_enable().

| PCI: delay configuration of SRIOV capability
| The SRIOV capability, namely page size and total_vfs of a device are
| configured during enumeration phase of the device.  This can potentially
| interfere with the PCI operations of the platform, if the IOV capability
| of the device is not enabled.

Fixes PCI device detection on IBM xSeries IBM 3850 M2 / x3950 M2
when using ACPI resources (_CRS).
This is default, a manual workaround (without this patch)
would be pci=nocrs boot param.

V2: Add dev_warn if the workaround is hit. This should reveal
how common such setups are (via google) and point to possible
problems if things are still not working as expected.

Manually fix up a semantic mis-merge wrt security_netlink_recv():

 - the interface was removed in commit fd7784615248 ("security: remove
   the security_netlink_recv hook as it is equivalent to capable()")

 - a new user of it appeared in commit a38f7907b926 ("crypto: Add
   userspace configuration API")

causing no automatic merge conflict, but Eric Paris pointed out the
issue.

module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.
