Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
scsi: bnx2fc: Make bnx2fc_recv_frame() mp safe
Running tests with a debug kernel shows that bnx2fc_recv_frame() is modifying the per_cpu lport stats counters in a non-mpsafe way. Just boot a debug kernel and run the bnx2fc driver with the hardware enabled.

Restore the old get_cpu/put_cpu code with some modifications to reduce the size of the critical section.
