  [SPARC64]: Kill 'prom_keyboard'.
  [SPARC]: Kill extern decl of 'panic_setup'.
  [SPARC64]: Delete 'boot_flags'.
  [SPARC64]: Kill unused function 'kernel_enter_debugger'.
  [SPARC64] arch/sparc64/kernel/unaligned.c: Use time_* macros
  [SPARC64]: Always register a PROM based early console.
  [SPARC64]: Update defconfig.
  [SPARC64]: Add -mtune=ultrasparc3 if possible.
  [SPARC64]: Remove Makefile code for ancient gcc and binutils.
  [SPARC64]: Remove DEBUG_BOOTMEM.
  [SPARC64]: Use shorter "get_zeroed_page" call.
  [SPARC]: Use shorter form of "get_zeroed_page".
