From e0a748983b07205d9f2f52230c897f49a2c84c8d Mon Sep 17 00:00:00 2001
From: Thomas Gleixner <tglx@linutronix.de>
Date: Tue, 14 Jul 2015 14:26:34 +0200
Subject: [PATCH 243/323] panic: skip get_random_bytes for RT_FULL in
init_oops_id
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.204-rt100.tar.xz
Disable on -RT. If this is invoked from irq-context we will have problems
to acquire the sleeping lock.
