Matthew Wilcox 3749c51ac6 PCI: Make current and maximum bus speeds part of the PCI core
Move the max_bus_speed and cur_bus_speed into the pci_bus.  Expose the
values through the PCI slot driver instead of the hotplug slot driver.
Update all the hotplug drivers to use the pci_bus instead of their own
data structures.

Kenji Kaneshige a6c0d5c6eb PCI hotplug: remove redundant .owner initializations
The "owner" field in struct hotplug_slot_ops is initialized by PCI
hotplug core. So each hotplug controller driver doesn't need to
initialize it.

Yinghai Lu e5198075c6 x86, apic: introduce io_apic_irq_attr
according to Ingo, io_apic irq-setup related functions have too many
parameters with a repetitive signature.

So reduce related funcs to get less params by passing a pointer
to a newly defined io_apic_irq_attr structure.

v2: io_apic_irq ==> irq_attr
    triggering ==> trigger

v3: add set_io_apic_irq_attr

Jaswinder Singh Rajput 824877111c x86, pci: move arch/x86/pci/pci.h to arch/x86/include/asm/pci_x86.h
Impact: cleanup

Now that arch/x86/pci/pci.h is used in a number of other places as well,
move the lowlevel x86 pci definitions into the architecture include files.
(not to be confused with the existing arch/x86/include/asm/pci.h file,
which provides public details about x86 PCI)

Tested on: X86_32_UP, X86_32_SMP and X86_64_SMP

Neil Horman 3e3d0e9246 PCI hotplug: ibmphp: Fix module ref count underflow
I happened to notice that the ibmphp hotplug driver does something
rather silly in its init routine.  It purposely calls module_put so as
to underflow its module ref count to avoid being removed from the
kernel.  This is bad practice, and wrong, since it provides a window for
subsequent module_gets to reset the refcount to zero, allowing an unload
to race in and cause all sorts of mysterious panics.  If the module is
unsafe to load, simply omitting the module_exit parameter is sufficient
to prevent the kernel from allowing the unload.

Jesper Juhl 029c3c133b PCI: Hotplug: Fix leaks in IBM Hot Plug Controller Driver - ibmphp_init_devno()
In drivers/pci/hotplug/ibmphp_core.c::ibmphp_init_devno() we allocate
space dynamically for a PCI irq routing table by calling
pcibios_get_irq_routing_table(), but we never free the allocated space.

This patch frees the allocated space at the function exit points.

Spotted by the Coverity checker. Compile tested only.

Please consider applying.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
