* Makefile_upgrade.inc:
  - A trailing space on the empty line below TO_REMOVE.

* sys/config/X86_64_GENERIC:
  - Remove the `device cryptodev` line at the end.

* sys/opencrypto/crypto.c:
  - There is one mention of '/dev/crypto' on line 1187; should update it.

* libtcplay:
  - Maybe should remove 'lib/libtcplay/crypto-dev.c'
* test/crypto/cryptoapi:
  - Maybe should remove 'crypto-dev.c' there as well.

* tools/tools/crypto:
  - May need to remove; or how to fix them?
* test/testcases/crypto:
  - May need to remove; or how to fix them?
  - Or freebsd/openbsd has better test cases without requiring /dev/crypto?
