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 --- Hari Bathini (2): makedumpfile: Initialize for vmalloc address translation support in PPC64 arch makedumpfile: vtop address translation support for vmalloc region in PPC64 arch arch/ppc64.c | 170 ++++++++++++++++++++++++++++++++++++++++++++++++++++---- makedumpfile.c | 9 +++ makedumpfile.h | 83 +++++++++++++++++++++++++++ 3 files changed, 249 insertions(+), 13 deletions(-) -- - Hari _______________________________________________ kexec mailing list kexec@lists.infradead.org http://lists.infradead.org/mailman/listinfo/kexec
