[PATCH] panic: call bust_spinlocks(0) before dying

From: Aaro Koskinen
Date: Fri Oct 02 2009 - 07:42:30 EST


Commit ffd71da4e3f323b7673b061e6f7e0d0c12dc2b49 moved bust_spinlocks(0)
to the end of the function, which in practice is never reached. As a
result console_unblank() is not called, and on some systems the user
may not see the panic message.
