From 6f1f942cd5fbbe308f912fc84e3f10fbc8113a68 Mon Sep 17 00:00:00 2001 From: He Ying Date: Thu, 6 May 2021 18:04:57 -0700 Subject: [PATCH] smp: kernel/panic.c - silence warnings We found these warnings in kernel/panic.c by using sparse tool: warning: symbol 'panic_smp_self_stop' was not declared. warning: symbol 'nmi_panic_self_stop' was not declared. warning: symbol 'crash_smp_send_stop' was not declared. To avoid them, add declarations for these three functions in include/linux/smp.h.
