History
Jonathan T. Looney 44b71282b5 When running with INVARIANTS, the kernel contains extra checks. However, 
these assumptions may not hold true once we've panic'd. Therefore, the
checks hold less value after a panic.  Additionally, if one of the checks
fails while we are already panic'd, this creates a double-panic which can
interfere with debugging the original panic.

Therefore, this commit allows an administrator to suppress a response to
KASSERT checks after a panic by setting a tunable/sysctl.  The
tunable/sysctl (debug.kassert.suppress_in_panic) defaults to being
enabled.
