Here's a backport of the arm64 kdump support added in v4.12. Tested on a Cavium ThunderX CRB1S and a Qualcomm QDF2400. The QDF2400 support has an outstanding issue where the crash*ing* kernel needs to be booted w/ maxcpus=1 in order for the crash kernel to successfully boot. This is also the case w/ upstream v4.12, and is still under investigation.
