New Revision: 363613
URL: https://svnweb.freebsd.org/changeset/base/363613

Log:
  Don't include T_USER in si_trapno reported to userland.
  
  Signals are only reported for user traps, so T_USER is redundant.  It
  is also a software convention and not included in the value reported
  by the hardware.
