+       for (; addr < (void *) end; addr += PAGE_SIZE)
+               flush_data_cache_page((unsigned long) addr);

dma_cache_wback() will be more efficient ?

Also, I personally think replacing all insb/insw/insl is a bit
overkill.  I'd prefer redefine insb/insw/insl in asm-mips/ide.h, but
I'm not sure it is enough. (really all ins[bwl] should take care of
the cache inconsistency?)
