From 7f328908f9cb69a72ce1c9279508c786cf85f1f5 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Mon, 10 Mar 2014 14:29:37 -0600 Subject: [PATCH] mtip32xx: fix bad use of smp_processor_id() mtip_pci_probe() dumps the current CPU when loaded, but it does so in a preemptible context. Hence smp_processor_id() correctly warns: BUG: using smp_processor_id() in preemptible [00000000] code: systemd-udevd/155 caller is mtip_pci_probe+0x53/0x880 [mtip32xx] Switch to raw_smp_processor_id(), since it's just informational and persistent accuracy isn't important.
