VPD quirks need to be called after the VPD capability is initialized. Since VPD initialization now runs after pci_fixup_header (due to the capabilities consolidation), VPD quirks should be done at pci_fixup_final stage correspondingly.

This patch adds the CONFIG_PCI_QUIRKS option which allows to remove all the PCI quirks, which are not necessarily used on embedded systems when PCI is working properly. As this is a size-reduction option, it depends on CONFIG_EMBEDDED.

For Broadcom 5706, 5708, 5709 rev. A nics, any read beyond the VPD end tag will hang the device. This problem was initially observed when a vpd entry was created in sysfs ('/sys/bus/pci/devices/<id>/vpd'). A read to this sysfs entry will dump 32k of data. Reading a full 32k will cause an access beyond the VPD end tag causing the device to hang. Once the device is hung, the bnx2 driver will not be able to reset the device. We believe that it is legal to read beyond the end tag and therefore the solution is to limit the read/write length. A majority of this patch is from Matthew Wilcox who gave code for reworking the PCI vpd size information. A PCI quirk added for the Broadcom NIC's to limit the read/write's.

This follows up 53a9bf42. Some newer CX700 BIOSes from our vendor have PCI Bus Parking disabled but PCI Master read caching enabled. This creates problems such as system freezing when both the network controller and the USB controller are active and one of them is pretty busy (e.g. heavy network traffic). This patch separates the checks and both the bus parking and the read caching are disabled independently if either is enabled by the BIOS.

This reverts commit 3c0a654e and fixes kernel bug #10245: http://bugzilla.kernel.org/show_bug.cgi?id=10245 The HP Compaq nc6120 has the same PCI sub-device ID as the nx6110, and the SMBus is used by ACPI for thermal management on the nc6120, so Linux should not attach a native driver to it. This means that this quirk is unsafe and has to be removed. I also added a comment to help developers realize that adding new IDs to this SMBus unhiding quirk table should be done only with great care, and in particular only after checking that ACPI is not making use of the SMBus.

This is the fix for the following problem: https://bugzilla.redhat.com/show_bug.cgi?id=227657 The bnx2 device 5706 complains about MSI not working behind a ServerWorks HT1000 PCIX bridge. An earlier commit to fix the problem: e3008ded: "PCI: disable MSI by default on systems with Serverworks HT1000 chips" was not entirely correct, and has been reverted. MSI does not work on the PCIX bus because the BIOS did not set the HT_MSI_FLAGS_ENABLE bit in the HyperTransport MSI capability on the bridge. We use the existing quirk_msi_ht_cap() to detect the problem and disable MSI in all buses behind it.
