Hi Vivek, Ok this is not our preferred solution but we can't expect that life is always easy ;-) Our s390 kernel maintainer Martin Schwidefsky agreed to send the following two patches upstream for 3.11: * s390/kdump: Disable mmap for s390 * s390/kdump: Allow copy_oldmem_page() copy to virtual memory @Andrew: Would you then take the "ELF header in new memory" patch series for 3.12?
