sparc64: Handle extremely large kernel TSB range flushes sanely.
[ Upstream commit 849c498766060a16aad5b0e0d03206726e7d2fa4 ]
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.
