2009-02-24T17:36:56+00:00

Move the enabling of interrupts after all of the data structures
are setup so that we can safely run the interrupt handler as
soon as it is registered.

PCI: pciehp: ignore undefined bit in link status register

2009-01-07T19:13:21+00:00

Bit 10 in Link Status register used to be defined as Training Error in
the PCI Express 1.0a specification. But it was removed by Training Error
ECN and is no longer defined. So pciehp must ignore the value read from
it.

PCI: pciehp: remove 'name' parameter

2008-10-22T23:42:42+00:00

We do not need to manage our own name parameter, especially since
the PCI core can change it on our behalf, in the case of duplicate
slot names.

Remove 'name' from pciehp's version of struct slot, and remove
unused 'task_list' as well.

PCI: pciehp: fix irq initialization

2008-10-20T17:53:47+00:00

Current pciehp driver gets irq number from pci_dev->irq. But because
pciehp driver is a pci express port service driver, it should get irq
number from pcie_device->irq.
