svn commit: r328057 - head/sys/opencrypto

[John Baldwin]

Author: jhb
Date: Tue Jan 16 19:41:18 2018
New Revision: 328057
URL: https://svnweb.freebsd.org/changeset/base/328057

Log:
  Split crp_buf into a union.
  
  This adds explicit crp_mbuf and crp_uio pointers of the right type to
  replace casts of crp_buf.  This does not sweep through changing existing
  code, but new code should use the correct fields instead of casts.
