I'm going to drop this in the next release. According to John, progress
has been made now that the ringbuffer changes were merged upstream:
- makedumpfile
  https://github.com/makedumpfile/makedumpfile/commit/c617ec63339222f3a44d73e36677a9acc8954ccd
  Should be part of to be released 1.6.9

- kexec-tools
  https://git.kernel.org/pub/scm/utils/kernel/kexec/kexec-tools.git/commit/?id=4149df9005f2cdd2ecf70058dfe7d72f48c3a68c
  Should be part of a post v2.0.20 release.

- crash
  https://github.com/crash-utility/crash/commit/a5531b24750e7949c35640d996ea14c0587938bc
  Has been merged into the 7.3.0 development phase a few hours ago.

- Tools shipped by the kernel
  - lx-dmesg (gdb helper script) in scripts/gdb/linux
  - dmesg (gdb macro) Documentation/admin-guide/kdump/gdbmacros.txt
  will be part of the v5.10 release.
