New Revision: 314370
URL: https://svnweb.freebsd.org/changeset/base/314370

Log:
  Unbreak kernel breakpoints, broken for ~4 years now
  
  When committing DTrace in 2012/2013 era I inadvertently broke breakpoints, by
  setting EXC_DTRACE to the same value as BKPT_INST.  Change EXC_DTRACE to a
  different, yet logically identical, trap (tw <all>,31,31).
  
  MFC after:	2 weeks
