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

fixed bus error handling for real this time (save registers before every instruction and push the saved registers if a bus error occurs, since the instruction may have changed registers before the bus error, and also stop the instruction immediately with longjmp so it won't change memory after the bus error)
