Sorry, I am not familiar with DWARF format, and KERNEL_IMAGE_SIZE is a
defined MACRO. I don't know what DW_TAG_XXX_type should be taken to
retrieve it when specify "-g" to generate vmcoreinfo file from vmlinux.
So drop this patch for now though it doesn't affect Dave's Crash code,
will make time to try to add it later, I need work on other urgent
things now. Or someone who is interested can add this.
Now only patch 1/2 is available.
Thanks
