Douglas Anderson a67a554d53 kdb: Don't back trace on a cpu that didn't round up ... [ Upstream commit 162bc7f5af ] If you have a CPU that fails to round up and then run 'btc' you'll end up crashing in kdb becaue we dereferenced NULL. Let's add a check. It's wise to also set the task to NULL when leaving the debugger so that if we fail to round up on a later entry into the debugger we won't backtrace a stale task.
