There is no memory_region_io(). And remove a stray '-'.

Hi Paolo,
    Seems the patch ignore the slight modification on that memory 
figure, So commit message isn`t consistent with the patch content. And 
actually I missed to remove a space between 7000 and 8000, since I 
removed a "-"

Oops, I forgot to adjust the commit message---I was about to answer on
your message to explain why I removed the second hunk.  Here:


        0      1000   2000   3000   4000   5000   6000   7000    8000
        |------|------|------|------|------|------|------|-------|
  A:    [                                                       ]
  C:    [CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC]
  B:                  [                          ]


It is correct to put 8000 right _after_ the closing bracket, because A
ends at 0x7FFF.  You can see how C and B are also aligned before the
tick at 6000.

Thanks,

Paolo
