With this change the KVA space sizing happens to be more in line with the MI one so up to at least 24GB machines KVA doesn't need to be limited manually. This is just another stopgap though, the real solution is to take advantage of ASI_ATOMIC_QUAD_LDD_PHYS on CPUs providing it so we don't need to lock the kernel TSB pages into the dTLB in the first place.
