Almost forgot about this....

With Russell's corrected bug and his request to capitalize the first letter
I get the following on the ep93xx platform:

Virtual kernel memory layout:
    vector  : 0xffff0000 - 0xffff1000   (   4 kB)
    fixmap  : 0xfff00000 - 0xfffe0000   ( 896 kB)
    DMA     : 0xffc00000 - 0xffe00000   (   2 MB)
    vmalloc : 0xc6800000 - 0xfe800000   ( 896 MB)
    lowmem  : 0xc0000000 - 0xc6000000   (  96 MB)
    modules : 0xbf000000 - 0xc0000000   (  16 MB)
      .init : 0xc0008000 - 0xc0028000   ( 128 kB)
      .text : 0xc0028000 - 0xc03a0000   (3552 kB)
      .data : 0xc03ba000 - 0xc03e2aa0   ( 163 kB)

which looks fine.  My only issue is, shouldn't the 'end' values all be -1.

Other than that you can add for ep93xx:
