Change Details

I'm finding that it's useful to have static global domainsets for use in kernel allocators (malloc(), kmem_malloc(), UMA, kstacks). Add some plumbing to make that easy: - Add a vm_phys routine that can be invoked by MD code once the NUMA topology is discovered. Right now this is only used by the SRAT/SLIT parser, but will likely be used by FDT code on non-ACPI systems in the future. - Predefined domainsets are allocated from .data instead of from the domainset zone. This lets us use them in UMA without introducing a bootstrapping issue. This results in a bit of bloat, but not much: struct domainset is 40 bytes with LP64, and MAXMEMDOM is small on all platforms. - Predefine domainset_roundrobin and domainset_prefer.
