- Currently the PMAP code is laid out to let the kernel TSB cover the whole KVA space using one locked 4MB dTLB entry per GB of physical memory. On Cheetah-class machines only the dt16 can hold locked entries though, which would be completely consumed for the kernel TSB on machines with >= 16GB. Therefore limit the KVA space to use no more than half of the lockable dTLB slots, given that we need them also for other things.
- Add sanity checks which ensure that we don't exhaust the (lockable) TLB slots.
