Hello Vivek, I finished the patches that add the stand-alone dump tools support on top of the recently sent v2 patch series. The following three patches implement the program check idea that we have discussed recently: [1] kdump: Add new machine_kexec_finish() architecture callback [2] s390: Add external kdump entry point for s390 stand-alone dump tools [3] kexec-tools: Emit program check on s390 for checksum failure Thanks!
