I'll get us started: - kaiser= - hidekernel= - unmapkernel= - hardenkaslr= - swuan=Off all of these, I think "unmapkernel" is the clear winner, since it says what it does in the tin (even if it misses the when). I'll have a think over the weekend.
On the x86 side we've been leaning toward renaming kaiser to something like "user pagetable isolation", so the boot parameter is something like "noupti". But I think the consensus is definitely to get rid of "kaiser".
