"PKRAM" Revived For Preserving Memory Pages Across Kexec'ing Kernels

Patches back in 2013 were proposed for "PRAM" as persistent over-kexec memory storage to allow saving of memory pages across kernel reboots via kexec or when hitting a new kernel via kexec.

This tracing framework originally developed for Solaris was fantastic back in the day but over the years Linux has stepped up its game with various efforts.
