kernel - pmap - more invltlb stuff
* Make sure pmap->pm_cache is cleared when a pmap gets reused,
fixing an issue where the pmap subsystem wasn't properly
invltlb'ing the recycled pmap due to stale cpu cache bits.
* Add sysctl vm.dreadful_invltlb (default to off) as a debugging aid.
Turning this on disables pmap->pm_cache and does an unconditional
invltlb on every pmap operation.
