From f56813f3470c5b4987963c3c41e4fe16b95c5a3f Mon Sep 17 00:00:00 2001 From: Igor Druzhinin Date: Fri, 19 Jul 2019 14:07:48 +0100 Subject: [PATCH] x86/crash: fix kexec transition breakage Following 6ff560f7f ("x86/SMP: don't try to stop already stopped CPUs") an incorrect condition was placed into kexec transition path leaving crashing CPU always online breaking kdump kernel entering. Correct it by unifying the condition with smp_send_stop().
