I like all of it, especially the fpu kernel thread part you did leave out for now, which I wanted since we started thinking about in-kernel audio mixing ;-} One minor nit: with the performance impact that high, and there being setups where runtime side channel attacks are totally not an issue, maybe we should leave the old code in place for now, #ifdef'd as default-off options to provide time for a full reconstruction (or untill the machine gets update to "the last decade" cpu)? I have a setup like that, but in my case throughput is not local cpu bound at all, so not a big deal for me - but I guess others could be affected (here it is: trusted admin-only server w/o any side channel attack surfaces, backup via rsync to CGD over ISCSI over VPN to off site device, slow VPN being the limiting factor - and don't ask, parts of that construction were not negotiable, like the final target device and the types of connections it offers).
