It kind of irked me that lmb was passed over for whatever vague reason
was given.

It works fine with memory hotplug on powerpc, so a lack of hotplug
support can't be an argument for not using it.

But hey, having yet another early memory allocator instead of making
one of the existing ones do what you want, that's fine right?
