Subject[PATCH 3.12 002/181] Revert "bio-integrity: Fix bio_integrity_verify segment start bug"
Date
3.12-stable review patch.  If anyone has any objections, please let me know.

===============

This reverts commit 7cbcb219e4113e10ce4b036118992abdbc4a8273,
misapplied upstream commit 5837c80e870bc3b12ac6a98cdc9ce7a9522a8fb6.

The upstream commit was applied twice to stable-3.12, the second time
to bio_integrity_generate. Revert this second application.
