* choose to use bit 47 in the tag. Also, since we never map anything
* at page zero in context zero, we use zero as an invalid tag entry.
* When the lock bit is set, this forces a tag comparison failure.

- * Currently, we allocate an 8K TSB per-process and we use it for both
- * I-TLB and D-TLB misses. Perhaps at some point we'll add code that
- * monitors the number of active pages in the process as we get
- * major/minor faults, and grow the TSB in response. The only trick
- * in implementing that is synchronizing the freeing of the old TSB

- * possible solution is to use RCU for the freeing of the TSB.
