Subject: [PATCH] crc32: remove useless __pure modifier from functions

From: Pekka Enberg <penberg@...helsinki.fi>

The pure attribute has absolutely no effect with GCC 4.2:

   text	   data	    bss	    dec	    hex	filename
   2456	      0	      0	   2456	    998	lib/crc32.o.old
   2456	      0	      0	   2456	    998	lib/crc32.o.new
