  "message": "Use proper abstractions in quirk_intel_irqbalance\n\nSince we may not have a pci_dev for the device we need to access, we can\u0027t\nuse pci_read_config_word.  But raw_pci_read is an internal implementation\ndetail; it\u0027s better to use the architected pci_bus_read_config_word\ninterface.  Using PCI_DEVFN instead of a mysterious constant helps\nreassure everyone that we really do intend to access device 8.\n\n[ Thanks to Grant Grundler for pointing out to me that this is exactly\n  what the write immediately above this is doing -- enabling device 8 to\n  respond to config space cycles.\n\t\t\t\t\t- Matthew\n\n  Grant also says:\n\n\t\"Can you also add a comment which points at the Intel\n\t documentation?\n\n\t The \u0027Intel E7320 Memory Controller Hub (MCH) Datasheet\u0027 at\n\n\t  http://download.intel.com/design/chipsets/datashts/30300702.pdf\n\n\t Page 69 documents register F4h (DEVPRES1).\n\n\t And I just doubled checked that the 0xf4 register value is\n\t restored later in the quirk (obvious when you look at the code\n\t but not from the patch\"\n\n  so here it is.\n\t\t\t\t\t - Linus ]\n\nSigned-off-by: Matthew Wilcox \u003cwilly@linux.intel.com\u003e\nAcked-by: Grant Grundler \u003cgrundler@parisc-linux.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
