In makedumpfile tool, currently there is no support for virtual to physical
address translation of vmalloc region  on PPC64 architecture. These patches
add this support.  The patches have been tested by  erasing data in vmalloc
region, verfying for eraseinfo in the resultant ELF dump and verifiying the
resultant ELF dump for sanity using crash utility. Also, tested the patches
successfully with eppic scripts.

Changes in v2:
1. Allocating memory to read page tables only when vmalloc address
   translation is requested.
2. Fixed coding style issues.
