2008-12-17PCI hotplug: ibmphp: Fix module ref count underflowNeil Horman1-5/+0
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.

2008-11-11PCI: ignore bit0 of _OSC return codeKenji Kaneshige1-7/+8
Currently acpi_run_osc() checks all the bits in _OSC result code (the first DWORD in the capabilities buffer) to see error condition. But the bit 0, which doesn't indicate any error, must be ignored. The bit 0 is used as the query flag at _OSC invocation time. Some platforms clear it during _OSC evaluation, but the others don't. On latter platforms, current acpi_run_osc() mis-detects error when _OSC is evaluated with query flag set because it doesn't ignore the bit 0. Because of this, the __acpi_query_osc() always fails on such platforms. And this is the cause of the problem that pci_osc_control_set() doesn't work since the commit 4e39432f4df544d3dfe4fc90a22d87de64d15815 which changed pci_osc_control_set() to use __acpi_query_osc().

2008-10-23PCI hotplug: cpqphp: fix kernel NULL pointer dereferenceKenji Kaneshige1-1/+1
The following patch fixes the regression in 2.6.27 that causes kernel NULL pointer dereference at cpqphp driver probe time. This patch should be backported to the .27 stable series. Seems to have been introduced by f46753c5e354b857b20ab8e0fe7b2579831dc369. The root cause of this problem seems that cpqphp driver calls pci_hp_register() wrongly. In current implementation, cpqphp driver passes 'ctrl->pci_dev->subordinate' as a second parameter for pci_hp_register(). But because hotplug slots and it's hotplug controller (exists as a pci funcion) are on the same bus, it should be 'ctrl->pci_dev->bus' instead.

2008-10-22PCI: Workaround invalid P2P bridge bus numbersBenjamin Herrenschmidt1-2/+10
Some firmware fail to properly configure P2P bridges, leaving them with invalid bus numbers. In some cases, this happens on some embedded 4xx boards as the result of the kernel allocating different bus space than the firmware does to host bridges while not setting pcibios_assign_all_busses() for various reasons. In other cases, it can just be bogus firmware. This adds some sanity checking to the PCI probing code. If a bridge is found whose primary bus number doesn't match the bus it's sitting on, or whose secondary bus number not strictly above it's primary bus number, then the bridge bus numbers are deconfigured in the first pass of pci_scan_bridge() to be re-assigned in the second pass.

2008-10-22PCI: rpaphp: kmalloc/kfree slot->name directlyAlex Chiang1-5/+3
rpaphp tends to use slot->name directly everywhere, and doesn't ever need slot->hotplug_slot->name. struct hotplug_slot->name is going away, so convert rpaphp directly manipulate its own slot->name everywhere, and don't bother touching slot->hotplug_slot->name.

2008-10-22PCI: pciehp: remove 'name' parameterAlex Chiang4-44/+52
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.
