2008-04-26x86: clear pci_mmcfg_virt when mmcfg get rejectedYinghai Lu
For x86_64, need to free pci_mmcfg_virt, and iounmap some pointers when MMCONF is not reserved in E820 or acpi _CRS and get rejected.

2008-02-10Change pci_raw_ops to pci_raw_read/writeMatthew Wilcox
We want to allow different implementations of pci_raw_ops for standard and extended config space on x86. Rather than clutter generic code with knowledge of this, we make pci_raw_ops private to x86 and use it to implement the new raw interface -- raw_pci_read() and raw_pci_write().

2008-02-10PCI x86: always use conf1 to access config space below 256 bytesIvan Kokshaysky
Thanks to Loic Prylli <loic@myri.com>, who originally proposed this idea. Always using legacy configuration mechanism for the legacy config space and extended mechanism (mmconf) for the extended config space is a simple and very logical approach. It's supposed to resolve all known mmconf problems. It still allows per-device quirks (tweaking dev->cfg_size). It also allows to get rid of mmconf fallback code.
