I spent two days (not full time) trying to make kexec work in qemu mips, without much success. Apparently it’s possible - and easy, because I’ve done it by accident - to configure the kernel in such a way that it has SMP support but lacks the hook to disable non-boot CPUs before execing the new kernel.

I can probably figure this out … but the whole reason I wanted to use kexec is to reboot from other people’s kernels, so if it’s this easy for me to build a kernel that accidentally doesn’t support it, maybe it’s easy for everyone else as well?
