+Subject: [PATCH 33/50] panic: Mark emergency section in warn
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.7/older/patches-6.7-rt6.tar.xz
+
+Mark the full contents of __warn() as an emergency section. In
+this section, the CPU will not perform console output for the
+printk() calls. Instead, a flushing of the console output will
+triggered when exiting the emergency section.
