However, non-atomic i2c transfers require preemption (e.g. in\nwait_for_completion() while waiting for the DMA).\n\npanic() calls preempt_disable_notrace() before calling\nemergency_restart(). Therefore, if an i2c device is used for the\nrestart, the xfer should be atomic. This avoids warnings like:\n\n[ 12.667612] WARNING: CPU: 1 PID: 1 at kernel/rcu/tree_plugin.h:318 rcu_note_context_switch+0x33c/0x6b0\n[ 12.676926] Voluntary context switch within RCU read-side
