Log:
SVN rev 223531 on 2011-06-25 10:28:16Z by avg
unconditionally stop other cpus when entering kdb in smp system
... and thus retire debug.kdb.stop_cpus tunable/sysctl.
The knob was to work around CPU stopping issues, which since have been
either fixed or greatly reduced. kdb should really operate in a special
environment with scheduler stopped and interrupts disabled to provide
deterministic debugging.
Discussed with: attilio, rwatson
X-MFC after: 2 months or never
