This patch adds support for the SGI UV3 hub to the common x2apic functions. The primary changes are to account for the similarities between UV2 and UV3 which are encompassed within the "UVX" nomenclature. One significant difference within UV3 is the handling of the MMIOH regions which are redirected to the target blade (with the device) in a different manner. It also now has two MMIOH regions for both small and large BARs. This aids in limiting the amount of physical address space removed from real memory that's used for I/O in the max config of 64TB.
