Thank you for merging my patches.

I tested the latest crash utility (crash-4.0-4.9), and I found a problem
that "kmem -p" fails like the following:

  crash> kmem -p

  kmem: invalid structure member offset: page_index
        FILE: memory.c  LINE: 4116  FUNCTION: dump_mem_map_SPARSEMEM()

  [/usr/bin/crash] error trace: 80a0a75 => 80a3020 => 80a1e25 => 8136ce7

  WARNING: Because this kernel was compiled with gcc version 4.1.2, certain
           commands or command options may fail unless crash is invoked with
           the  "--readnow" command line option.

  kmem: invalid structure member offset: page_index
        FILE: memory.c  LINE: 4116  FUNCTION: dump_mem_map_SPARSEMEM()

  crash>

To solve it, this patch fixes a typo for getting the offset "page.index".


Thanks
