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 v3:
Added the buffer to read page tables in DumpInfo structure and freeing it
before exiting the tool
