If you know it, please let me know. /* * Certain architectures such as x86_64 and ia64 require a separate * PT_LOAD program header for the kernel. This is controlled through * info->kern_size. * * 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. * * In the relocatable kernel case this PT_LOAD segment is used to tell * where the kernel was actually loaded which may be different from * the load address present in the vmlinux file. * * The extra kernel PT_LOAD program header results in a vmcore file * which is larger than the size of the physical memory. This is * because the memory for the kernel is present both in the kernel * PT_LOAD program header and in the physical RAM program headers. */ Thanks, Bernhard
