-Subject: [PATCH 091/134] printk: Add this_cpu_in_panic()
-Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.6/older/patches-6.6.7-rt18.tar.xz
-
-There is already panic_in_progress() and other_cpu_in_panic(),
-but checking if the current CPU is the panic CPU must still be
-open coded.
-
-Add this_cpu_in_panic() to complete the set.
