From 598543b96b715ed360718ca3597ad4a2eda53241 Mon Sep 17 00:00:00 2001
From: John Ogness <john.ogness@linutronix.de>
Date: Mon, 30 Nov 2020 01:42:03 +0106
Subject: [PATCH 101/323] printk: relocate printk_delay() and vprintk_default()
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.204-rt100.tar.xz
Move printk_delay() and vprintk_default() "as is" further up so that
they can be used by new functions in an upcoming commit.
