Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86-bigbox-pci
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86-bigbox-pci: x86: add pci=check_enable_amd_mmconf and dmi check x86: work around io allocation overlap of HT links acpi: get boot_cpu_id as early for k8_scan_nodes x86_64: don't need set default res if only have one root bus x86: double check the multi root bus with fam10h mmconf x86: multi pci root bus with different io resource range, on 64-bit x86: use bus conf in NB conf fun1 to get bus range on, on 64-bit x86: get mp_bus_to_node early x86 pci: remove checking type for mmconfig probe x86: remove unneeded check in mmconf reject driver core: try parent numa_node at first before using default x86: seperate mmconf for fam10h out from setup_64.c x86: if acpi=off, force setting the mmconf for fam10h x86_64: check MSR to get MMCONFIG for AMD Family 10h x86_64: check and enable MMCONFIG for AMD Family 10h x86_64: set cfg_size for AMD Family 10h in case MMCONFIG x86: mmconf enable mcfg early x86: clear pci_mmcfg_virt when mmcfg get rejected x86: validate against acpi motherboard resources Fixed up fairly trivial conflicts in arch/x86/pci/{init.c,pci.h} due to OLPC support manually.
