From e7a9b05ca4c707ff4b46a77963db48d085d383e0 Mon Sep 17 00:00:00 2001 From: Jan Glauber Date: Mon, 9 Apr 2018 17:45:54 +0200 Subject: crypto: cavium - Fix smp_processor_id() warnings Switch to raw_smp_processor_id() to prevent a number of warnings from kernel debugging. We do not care about preemption here, as the CPU number is only used as a poor mans load balancing or device selection. If preemption happens during a compress/decompress operation a small performance hit will occur but everything will continue to work, so just ignore it.
