x86_64: SPARSEMEM_VMEMMAP 2M page size support
...
x86_64 uses 2M page table entries to map its 1-1 kernel space. We also
implement the virtual memmap using 2M page table entries. So there is no
additional runtime overhead over FLATMEM, initialisation is slightly more
complex. As FLATMEM still references memory to obtain the mem_map pointer and
SPARSEMEM_VMEMMAP uses a compile time constant, SPARSEMEM_VMEMMAP should be
superior.
With this SPARSEMEM becomes the most efficient way of handling virt_to_page,
pfn_to_page and friends for UP, SMP and NUMA on x86_64.

PCI: X86: Introduce and enable PCI domain support
...
* fix bug in pci_read() and pci_write() which prevented PCI domain
support from working (hardcoded domain 0).
* unconditionally enable CONFIG_PCI_DOMAINS
* implement pci_domain_nr() and pci_proc_domain(), as required of
all arches when CONFIG_PCI_DOMAINS is enabled.
* store domain in struct pci_sysdata, as assigned by ACPI
* support "pci=nodomains"
