Looking a little more closely at the users there is a clear demand in the kernel for some kind of forced reboot. Coming from software watchdog timers and the like, and it makes sense for sysrq-b to call the same thing.
However I'm not at all certain that we want the software is hosed reboot dammit, to be the same as the graceful reboot path.
There are a lot of things we can do on the graceful reboot path like switch to the bootstrap cpu, attempt to make BIOS calls to perform the reboot etc, that I'm not at all certain we want to perform on the under more dire circumstances.
If it weren't simply overkill I'd say in the freaked out kernel reboot case we want to kexec to a sane kernel and then reboot from there.
