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
Would you then take the "ELF header in new memory" patch series for 3.12?
