Prarit Bhargava ee527cd3a2 Use stop_machine_run in the Intel RNG driver ... Replace call_smp_function with stop_machine_run in the Intel RNG driver. CPU A has done read_lock(&lock) CPU B has done write_lock_irq(&lock) and is waiting for A to release the lock. A third CPU calls call_smp_function and issues the IPI. CPU A takes CPU C's IPI. CPU B is waiting with interrupts disabled and does not see the IPI. CPU C is stuck waiting for CPU B to respond to the IPI. Deadlock. The solution is to use stop_machine_run instead of call_smp_function (call_smp_function should not be called in situations where the CPUs may be suspended).
