FUJITA Tomonori 5286944d75 alpha: fix compile errors in dma-mapping-common.h 
The commit c186caca3d leads to the
following errors with CONFIG_ALPHA_{TSUNAMI, TITAN, RAWHIDE, MARVEL}:
/home/fujita/git/linux-2.6/include/asm-generic/dma-mapping-common.h: In
function `dma_map_sg_attrs':
/home/fujita/git/linux-2.6/include/asm-generic/dma-mapping-common.h:49:
error: implicit declaration of function `for_each_sg'
/home/fujita/git/linux-2.6/include/asm-generic/dma-mapping-common.h:50:
error: syntax error before "kmemcheck_mark_initialized"
