Series looks reasonable to me. The one thing that makes me nervous is
4/11 mentioning the BIOS, which honestly seems like an insane thing to
let your BIOS have _any_ say in, but then Intel sure does like to give
the BIOS a chance to make the OS less functional. The code in 7/11
effectively limits things to between 4k and 1M; does that actually make
sense? I can't imagine wanting to allocate only 4k if it turns out we'd
always need at least (say) 32k.
I have admittedly not read any of the docs on how this is meant to work,
apologies if that'd answer this.
