Zhang Yanmin d71374dafb [PATCH] PCI: fix race with pci_walk_bus and pci_destroy_dev
pci_walk_bus has a race with pci_destroy_dev. When cb is called
in pci_walk_bus, pci_destroy_dev might unlink the dev pointed by next.
Later on in the next loop, pointer next becomes NULL and cause
kernel panic.

Below patch against 2.6.17-rc4 fixes it by changing pci_bus_lock (spin_lock)
to pci_bus_sem (rw_semaphore).

Paul Mackerras cecf4864cf [PATCH] PCI: Add pci_walk_bus function to PCI core (nonrecursive)
The PCI error recovery infrastructure needs to be able to contact all
the drivers affected by a PCI error event, which may mean traversing
all the devices under a given PCI-PCI bridge.  This patch adds a
function to the PCI core that traverses all the PCI devices on a PCI
bus and under any PCI-PCI bridges on that bus (and so on), calling a
given function for each device.  This provides a way for the error
recovery code to iterate through all devices that are affected by an
error event.

This version is not implemented as a recursive function.  Instead,
when we reach a PCI-PCI bridge, we set the pointers to start doing the
devices on the bus under the bridge, and when we reach the end of a
bus's devices, we use the bus->self pointer to go back up to the next
higher bus and continue doing its devices.

Linus Torvalds 688d191821 pci: make bus resource start address override minimum IO address
The reason we have PCIBIOS_MIN_IO and PCIBIOS_MIN_CARDBUS_IO is because
we want to protect badly documented motherboard PCI resources and thus
don't want to allocate new resources in low IO/MEM space.

However, if we have already discovered a PCI bridge with a specified
resource base, that should override that decision.

This change will allow us to move the "careful" region upwards without
resulting in problems allocating resources in low mappings.  This was
brought on by us having allocated a bus resource at 0x1000, conflicting
with a undocumented VAIO Sony PI resources.

Rajesh Shah 6ef6f0e33c [PATCH] acpi bridge hotadd: Link newly created pci child bus to its parent on creation
When a pci child bus is created, add it to the parent's children list
immediately rather than waiting till pci_bus_add_devices().  For hot-plug
bridges/devices, pci_bus_add_devices() may be called much later, after they
have been properly configured.  In the meantime, this allows us to use the
normal pci bus search functions for the hot-plug bridges/buses.

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!
