    arch/tile: Miscellaneous cleanup changes. · 0707ad30
    Chris Metcalf authored
    This commit is primarily changes caused by reviewing "sparse"
    and "checkpatch" output on our sources, so is somewhat noisy, since
    things like "printk() -> pr_err()" (or whatever) throughout the
    codebase tend to get tedious to read.  Rather than trying to tease
    apart precisely which things changed due to which type of code
    review, this commit includes various cleanups in the code:
    
    - sparse: Add declarations in headers for globals.
    - sparse: Fix __user annotations.
    - sparse: Using gfp_t consistently instead of int.
    - sparse: removing functions not actually used.
    - checkpatch: Clean up printk() warnings by using pr_info(), etc.;
      also avoid partial-line printks except in bootup code.
      - checkpatch: Use exposed structs rather than typedefs.
      - checkpatch: Change some C99 comments to C89 comments.
    
    In addition, a couple of minor other changes are rolled in
    to this commit:
    
    - Add support for a "raise" instruction to cause SIGFPE, etc., to be raised.
    - Remove some compat code that is unnecessary when we fully eliminate
      some of the deprecated syscalls from the generic syscall ABI.
    - Update the tile_defconfig to reflect current config contents.
