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.
