      arch/tile: finish enabling support for TILE-Gx 64-bit chip · 18aecc2b

      This support was partially present in the existing code (look for
      "__tilegx__" ifdefs) but with this change you can build a working
      kernel using the TILE-Gx toolchain and ARCH=tilegx.
      
      Most of these files are new, generally adding a foo_64.c file
      where previously there was just a foo_32.c file.
      
      The ARCH=tilegx directive redirects to arch/tile, not arch/tilegx,
      using the existing SRCARCH mechanism in the top-level Makefile.
      
      Changes to existing files:
      
      - <asm/bitops.h> and <asm/bitops_32.h> changed to factor the
        include of <asm-generic/bitops/non-atomic.h> in the common header.
      
      - <asm/compat.h> and arch/tile/kernel/compat.c changed to remove
        the "const" markers I had put on compat_sys_execve() when trying
        to match some recent similar changes to the non-compat execve.
        It turns out the compat version wasn't "upgraded" to use const.
      
      - <asm/opcode-tile_64.h> and <asm/opcode_constants_64.h> were
        previously included accidentally, with the 32-bit contents.  Now
        they have the proper 64-bit contents.
      
      Finally, I had to hack the existing hacky drivers/input/input-compat.h
      to add yet another "#ifdef" for INPUT_COMPAT_TEST (same as x86_64).
