David S. Miller 849c498766 sparc64: Handle extremely large kernel TSB range flushes sanely. 
If the number of pages we are flushing is more than twice the number
of entries in the TSB, just scan the TSB table for matches rather
than probing each and every page in the range.

Based upon a patch and report by James Clarke.
