      PCI: make no_pci_devices() use the pci_bus_type list · 70308923
      Greg Kroah-Hartman 提交于
      no_pci_devices() should use the driver core list of PCI devices, not our
      "separate" one.

      PCI: remove initial bios sort of PCI devices on x86 · 1ba6ab11
      Greg Kroah-Hartman 提交于
      We currently keep 2 lists of PCI devices in the system, one in the
      driver core, and one all on its own.  This second list is sorted at boot
      time, in "BIOS" order, to try to remain compatible with older kernels
      (2.2 and earlier days).  There was also a "nosort" option to turn this
      sorting off, to remain compatible with even older kernel versions, but
      that just ends up being what we have been doing from 2.5 days...
      
      Unfortunately, the second list of devices is not really ever used to 
      determine the probing order of PCI devices or drivers[1].  That is done
      using the driver core list instead.  This change happened back in the
      early 2.5 days.
      
      Relying on BIOS ording for the binding of drivers to specific device
      names is problematic for many reasons, and userspace tools like udev
      exist to properly name devices in a persistant manner if that is needed,
      no reliance on the BIOS is needed.
      
      Matt Domsch and others at Dell noticed this back in 2006, and added a
      boot option to sort the PCI device lists (both of them) in a
      breadth-first manner to help remain compatible with the 2.4 order, if
      needed for any reason.  This option is not going away, as some systems
      rely on them.
      
      This patch removes the sorting of the internal PCI device list in "BIOS"
      mode, as it's not needed at all anymore, and hasn't for many years.
      I've also removed the PCI flags for this from some other arches that for
      some reason defined them, but never used them.
      
      This should not change the ordering of any drivers or device probing.
      
      [1] The old-style pci_get_device and pci_find_device() still used this
      sorting order, but there are very few drivers that use these functions,
      as they are deprecated for use in this manner.  If for some reason, a
      driver rely on the order and uses these functions, the breadth-first
      boot option will resolve any problem.

      This removes the depandancy of the cpcihp driver from the PCI_LEGACY

      PCI: clean up search.c a lot · 95247b57
      Greg Kroah-Hartman 提交于
      This cleans up the search.c file, now using the pci list of devices that
      are created for the driver core, instead of relying on our separate list
      of devices.  It's better to use the functions already created for this
      kind of thing, instead of rolling our own all the time.
      
      This work is done in anticipation of getting rid of that second list of
      pci devices all together.
      
      And it ends up saving code, always a nice benefit.
      
      This also removes one compiler warning for when CONFIG_PCI_LEGACY is
      enabled as we no longer internally use the deprecated functions anymore.

      PCI: remove pci_get_device_reverse · 34220909
      Greg Kroah-Hartman 提交于
      This removes the pci_get_device_reverse function as there should not be
      any need to walk pci devices backwards anymore.  All users of this call
      are now gone from the tree, so it is safe to remove it.
