      Remove unnecessary cast in prefetch() · 4ecbca85
      Serge Belyshev authored
      It is ok to call prefetch() function with NULL argument, as specifically
      commented in include/linux/prefetch.h.  But in standard C, it is invalid
      to dereference NULL pointer (see C99 standard 6.5.3.2 paragraph 4 and
      note #84).
      
      prefetch() has a memory reference for its argument.
      
      Newer gcc versions (4.3 and above) will use that to conclude that "x"
      argument is non-null and thus wreaking havok everywhere prefetch() was
      inlined.
      
      Fixed by removing cast and changing asm constraint.
      
      [ It seems in theory gcc 4.2 could miscompile this too; although no
        cases known.  In 2.6.24 we should probably switch to
        __builtin_prefetch() instead, but this is a simpler fix for now.
