I'm unable to interpret one of the comments in kexec/crashdump-elf.c which says, " The separate PT_LOAD program header is required either because the kernel is mapped at a different location than the rest of the physical memory or because we need to support relocatable kernels. Or both as on x86_64. " Can you please provide some more clarification for this so that i can figure out whether a separate PT_LOAD header is required for ARM architecture as well (esp. the "kernel mapped to diff. loc. part of the comment").
