  sparc: sunzilog uart order
  [SPARC64]: Detect trap frames in stack backtraces.
  [SPARC64]: %l6 trap return handling no longer necessary.
  [SPARC64]: Use trap type stored in pt_regs to handle syscall restart.
  [SPARC64]: Store magic cookie and trap type in pt_regs.
  [SPARC64]: PROM debug console can be CON_ANYTIME.
  sparc64: cleanup after SunOS/Solaris binary emulation removal
  sparc: cleanup after SunOS binary emulation removal
  [SPARC64]: Add NUMA support.

  [SPARC64]: Decrease SECTION_SIZE_BITS to 30.
  [SPARC64]: Initialize MDESC earlier and use lmb_alloc()
  [SPARC64]: Use lmb_alloc() for PROM device tree.
  [SPARC64]: Call real_setup_per_cpu_areas() earlier and use lmb_alloc().
