Subject: [PATCH 225/354] panic: skip get_random_bytes for RT_FULL in
init_oops_id
Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=7dd5b80bbfca25a4215c5570ac68f7842ff3fc69
Disable on -RT. If this is invoked from irq-context we will have problems
to acquire the sleeping lock.
