2009-03-20PCI: PCIe portdrv: eliminate double kfree in remove pathAlex Chiang
Commit 55633af3 (PCIe portdrv: Use driver data to simplify code) added a kfree of the driver private data in pcie_port_device_remove but forgot to remove the old kfree from pcie_portdrv_remove.

2009-03-19PCI: PCIe portdrv: Do not enable port device before setting up interruptsRafael J. Wysocki
The PCI Express port driver calls pci_enable_device() before setting up interrupts, which is wrong, because if there is an interrupt pin configured for the port, pci_enable_device() will likely set up an interrupt link for it. However, this shouldn't be done if either MSI or MSI-X interrupt mode is chosen for the port. The solution is to call pci_enable_device() after setting up interrupts, because in that case the interrupt link won't be set up if MSI or MSI-X are enabled. Signed-off-by: Rafael J.

2009-02-24PCI: Enable PCIe AER only after checking firmware supportAndrew Patterson
The PCIe port driver currently sets the PCIe AER error reporting bits for any root or switch port without first checking to see if firmware will grant control. This patch moves setting these bits to the AER service driver aer_enable_port routine. The bits are then set for the root port and any downstream switch ports after the check for firmware support (aer_osc_setup) is made. The patch also unsets the bits in a similar fashion when the AER service driver is unloaded.

2009-02-04PCI: PCIe portdrv: Simplify suspend and resumeRafael J. Wysocki
Simplify suspend and resume of the PCI Express port driver. It no longer needs to save and restore the standard configuration space of the device; this is now done by the PCI PM core layer.

2009-01-07PCI PM: Split PCI Express port suspend-resumeRafael J. Wysocki
Suspend-resume of PCI Express ports has recently been moved into _suspend_late() and _resume_early() callbacks, but some functions executed from there should not be called with interrupts disabled, eg. pci_enable_device(). For this reason, split the suspend-resume of PCI Express ports into parts to be executed with interrupts disabled and with interrupts enabled. Signed-off-by: Rafael J.

2009-01-07PCI: Suspend and resume PCI Express ports with interrupts disabledRafael J. Wysocki
I don't see why the suspend and resume of PCI Express ports should be handled with interrupts enabled and it may even lead to problems in some situations. For this reason, move the suspending and resuming of PCI Express ports into ->suspend_late() and ->resume_early() callbacks executed with interrupts disabled.

2005-10-30[PATCH] fix missing includesTim Schmielau
I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

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!
