Author: jhibbits Date: Tue Apr 10 21:14:54 2018 New Revision: 332393 URL: https://svnweb.freebsd.org/changeset/base/332393 Log: Reenter KDB on fault on powerpc, instead of panicking Most other architectures already re-enter KDB on faults, powerpc and mips are the only outliers. Correct this for powerpc, so that now bad addresses can be handled gracefully instead of panicking.
