Close. But no cigar. Now I get:
CC arch/ia64/mm/init.o
arch/ia64/mm/init.c:75:6: error: redefinition of ‘arch_sync_dma_for_cpu’
./include/linux/dma-noncoherent.h:61:20: note: previous definition of
‘arch_sync_dma_for_cpu’ was here
make[1]: *** [arch/ia64/mm/init.o] Error 1
make: *** [arch/ia64/mm/init.o] Error 2
