2009-09-09PCI: Document pci_ids.h addition policy.Dave Jones
IDs should generally only be added to pci_ids.h when they're shared across several files in the tree. IDs that are just used by a single driver should be defined in the driver instead. Perhaps documenting this is a good idea to prevent things being moved there, as it still seems to be happening judging from the git log. (based on discussion w/gregkh and others).

2009-09-09PCI: expose function reset capability in sysfsMichael S. Tsirkin
Some devices allow an individual function to be reset without affecting other functions in the same device: that's what pci_reset_function does. For devices that have this support, expose reset attribite in sysfs. This is useful e.g. for virtualization, where a qemu userspace process wants to reset the device when the guest is reset, to emulate machine reboot as closely as possible.

2009-09-09PCI Hotplug: acpiphp: get pci_bus from acpi handle correctlyAlex Chiang
We cannot simply call acpi_get_pci_dev() on any random ACPI handle and hope that it works, because a PCI root bridge may not have an associated struct pci_dev. This is allowed per the PCI specification, and is referred to as a non-materialized bridge. So, depending on the type of PCI bridge that the handle points to, use the appropriate interface to return the struct pci_bus correctly.

2009-09-09x86/PCI: initialize PCI bus node numbers earlyJesse Barnes
The current mp_bus_to_node array is initialized only by AMD specific code, since AMD platforms have registers that can be used for determining mode numbers. On new Intel platforms it's necessary to initialize this array as well though, otherwise all PCI node numbers will be 0, when in fact they should be -1 (indicating that I/O isn't tied to any particular node). So move the mp_bus_to_node code into the common PCI code, and initialize it early with a default value of -1. This may be overridden later by arch code (e.g. the AMD code). With this change, PCI consistent memory and other node specific allocations (e.g. skbuff allocs) should occur on the "current" node. If, for performance reasons, applications want to be bound to specific nodes, they should open their devices only after being pinned to the CPU where they'll run, for maximum locality.

2009-09-08i915: disable interrupts before tearing down GEM stateLinus Torvalds
Reinette Chatre reports a frozen system (with blinking keyboard LEDs) when switching from graphics mode to the text console, or when suspending (which does the same thing). With netconsole, the oops turned out to be BUG: unable to handle kernel NULL pointer dereference at 0000000000000084 IP: [<ffffffffa03ecaab>] i915_driver_irq_handler+0x26b/0xd20 [i915] and it's due to the i915_gem.c code doing drm_irq_uninstall() after having done i915_gem_idle(). And the i915_gem_idle() path will do i915_gem_idle() -> i915_gem_cleanup_ringbuffer() -> i915_gem_cleanup_hws() -> dev_priv->hw_status_page = NULL; but if an i915 interrupt comes in after this stage, it may want to access that hw_status_page, and gets the above NULL pointer dereference. And since the NULL pointer dereference happens from within an interrupt, and with the screen still in graphics mode, the common end result is simply a silently hung machine. Fix it by simply uninstalling the irq handler before idling rather than after.
