Subject: [PATCH] iscsi: Use GFP_ATOMIC in iscsi_offload_mesg().

From: "Michael Chan" <mchan-dY08KVG/lbpWk0Htik3J/[email-masked]>
Date: Wed, 29 Jul 2009 11:49:52 -0700

Changing to GFP_ATOMIC because the only caller in cnic/bnx2i may
be calling this function while holding spin_lock.

This problem was discovered by Mike Christie.
