	these are the new  dynamic DMA mapping stuff, which sparc64
(others?) use.  i386 and us use static so we just 'fake' those functions.
they should be empty functions in <asm/pci.h>.  look at asm-i386/pci.h if
you need help.

	you will also run into problems with the new rw mutuxes, its a
mixture of rw spinlocks and semaphores.  there's a few asm functions which
need to be implemented and I have hack together a few of them.  You can
look at the sparc implementation if you wish.
