289908743e Fix a few bugs in the SRAT parsing code:
- Actually increment ndomain when building our list of known domains
  so that we can properly renumber them to be 0-based and dense.
- If the number of domains exceeds the configured maximum (VM_NDOMAIN),
  bail out of processing the SRAT and disable NUMA rather than hitting an
  obscure panic later.
- Don't bother parsing the SRAT at all if VM_NDOMAIN is set to 1 to
  disable NUMA (the default).

4d99cfb313 Ignore SRAT memory entries if the memory range does not overlap with an
existing phys_avail[] table.  If a hw.physmem setting causes a memory
domain to not be present in phys_avail[], the SRAT table will now be
ignored rather than triggering a panic when a CPU in the missing domain
tries to allocate a page.

6676877bd9 When performing a sanity check on the SRAT table to ensure that each
memory domain has an assigned CPU, ignore disabled CPUs.  Previously
disabled CPUs were counted as being in domain 0.

dd540b4623 Add a parser for the ACPI SRAT table for amd64 and i386. It sets
PCPU(domain) for each CPU and populates a mem_affinity array suitable
for the NUMA support in the physical memory allocator.
