      PCI: x86: use generic pci_enable_resources() · b81d988c
      由 Bjorn Helgaas 提交于 
      Use the generic pci_enable_resources() instead of the arch-specific code.

Unlike this arch-specific code, the generic version:

      PCI: Include PCI domain in PCI bus names on x86/x86_64 · cb3576fa
      由 Gary Hade 提交于 
      The PCI bus names included in /proc/iomem and /proc/ioports are
of the form 'PCI Bus #XX' where XX is the bus number.  This patch
changes the naming to 'PCI Bus XXXX:YY' where XXXX is the domain
number and YY is the bus number.  For example, PCI bus 14 in
domain 0 will show as 'PCI Bus 0000:14' instead of 'PCI Bus #14'.
This change makes the naming consistent with other architectures
such as ia64 where multiple PCI domain support has been around
longer.

      PCI: remove pcibios_fixup_ghosts() · 6355f3d1
      由 Greg Kroah-Hartman 提交于 
      This function was obviously never being used since early 2.5 days as any
device that it would try to remove would never really be removed from
the system due to the PCI device list being held in the driver core, not
the general list of PCI devices.

As we have not had a single report of a problem here in 4 years, I think
it's safe to remove now.

      PCI: remove initial bios sort of PCI devices on x86 · 1ba6ab11
      由 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.

      PM: Remove destroy_suspended_device() · b844eba2
      由 Rafael J. Wysocki 提交于 
      After 2.6.24 there was a plan to make the PM core acquire all device
semaphores during a suspend/hibernation to protect itself from
concurrent operations involving device objects.  That proved to be
too heavy-handed and we found a better way to achieve the goal, but
before it happened, we had introduced the functions
device_pm_schedule_removal() and destroy_suspended_device() to allow
drivers to "safely" destroy a suspended device and we had adapted some
drivers to use them.  Now that these functions are no longer necessary,
it seems reasonable to remove them and modify their users to use the
normal device unregistration instead.

      Firmware: add iSCSI iBFT Support · 138fe4e0
      由 Konrad Rzeszutek 提交于 
      Add /sysfs/firmware/ibft/[initiator|targetX|ethernetX] directories along with
text properties which export the the iSCSI Boot Firmware Table (iBFT)
structure.

What is iSCSI Boot Firmware Table?  It is a mechanism for the iSCSI tools to
extract from the machine NICs the iSCSI connection information so that they
can automagically mount the iSCSI share/target.  Currently the iSCSI
information is hard-coded in the initrd.  The /sysfs entries are read-only
one-name-and-value fields.

The usual set of data exposed is:

# for a in `find /sys/firmware/ibft/ -type f -print`; do  echo -n "$a: ";  cat $a; done

      x86: convert cpumask_of_cpu macro to allocated array · 9f0e8d04
      由 Mike Travis 提交于 
        * Here is a simple patch to use an allocated array of cpumasks to
    represent cpumask_of_cpu() instead of constructing one on the stack.
    It's based on the Kconfig option "HAVE_CPUMASK_OF_CPU_MAP" which is
    currently only set for x86_64 SMP.  Otherwise the the existing
    cpumask_of_cpu() is used but has been changed to produce an lvalue
    so a pointer to it can be used.
