Hello Vivek, To make progress and for getting at least the "standard" kdump port upstream soon, I send you now the updated patch series that contain the s390 kdump port without stand-alone dump support. The support for stand-alone dump tools can be added later. Main changes compared to version 1: 1. We use purgatory code 2. We use pre-allocated ELF core header 3. Registers are saved in old kernel 4. Removed meminfo The following patches are most interesting for you: [1-4] Common code changes [9] S390 kdump kernel backend [10] S390 kdump kexec-tools backend Patches 5-8 are s390 specific preparation patches for the kdump port. I hope we will make progress. Thanks! Michael
