This is an archive of my past work on the Linux Kernel Crash Dump project. The most notable piece of this is support for polling I/O, which made LKCD dramatically more robust (it's designed to run while the kernel is panicking, which means the usual interrupt-driven I/O path isn't reliable). There are also some patches to improve scalability to hundreds of processors.
LKCD was eventually supplanted by kexec/kdump, so it's unlikely that anyone would want to run this code nowadays.
