   drivers/scsi/pluto.c contains the following code:
   
   #ifdef __sparc_v9__
   			host->unchecked_isa_dma = 1;
   #endif
   
   The only thing host->unchecked_isa_dma = 1 does is to add a __GFP_DMA
   flag to certain memory allocations, but IIRC __GFP_DMA is a noop on
   sparcv9.  So what is this supposed to do?

It's bogus, delete it.
