treat all DMA reads/writes as kernel mode (previously it would depend on whether the processor happens to be in user mode or kernel mode when the DMA completes, which is totally incorrect); handle 32-bit accesses that straddle page boundaries properly (all 32-bit accesses are now split into two 16-bit accesses); allow reads to the entire zero page, rather than just address 0
