Log:
  [arm64] Bump MAXMEMDOM value to 8 to match amd64
  
  On some of the server-grade ARM64 machines the number of NUMA domains is higher
  than 2. When booting GENERIC kernel on such machines the SRAT parser fails
  leaving the system with a single domain. To make GENERIC kernel usable on those
  server, match the parameter value with the one for amd64 arch.
