svn commit: r283870 - head/sys/amd64/amd64

New Revision: 283870
URL: https://svnweb.freebsd.org/changeset/base/283870

Log:
  Remove unneeded NULL checks in amd64's trap_fatal().
  
  Since td_name is an array member of struct thread, it can never be NULL,
  so the check can be removed.  In addition, curproc can never be NULL,
  so remove the if statement, and splice the two printfs() together.
  
  While here, remove the u_long cast, and use the correct printf format
  specifier curproc->p_pid.
