    arch/tile: fix memchr() not to dereference memory for zero length · 3edabee2
    Chris Metcalf authored
    This change fixes a bug that memchr() will read the first word
    of the source even if the length is zero.  Ironically, the code
    was originally written with a test to avoid exactly this problem,
    but to make the code conform to Linux coding standards with all
    declarations preceding all statements, the first load from memory
    was moved up above that test as the initial value for a variable.
    
    The change just moves all the variable declarations to the top
    of the file, with no initializers, so that the test can also be
    at the top of the file.
