Official description
In the Linux kernel, the following vulnerability has been resolved:
scsi: smartpqi: Fix smp_processor_id() call trace for preemptible kernels
Correct kernel call trace when calling smp_processor_id() when called in preemptible kernels by using raw_smp_processor_id().
smp_processor_id() checks to see if preemption is disabled and if not, issue an error message followed by a call to dump_stack().
