New Revision: 197474
URL: http://svn.freebsd.org/changeset/base/197474

Log:
  MFC r196990:
  cr_groups is no longer embedded in struct ucred and is instead stored
  in a seperate array.  As such we need to use kvm_read rather than bcopy
  to populate the ki_groups field.
  
  This fixes a crash when running ps -ax on a coredump.
