+Subject: ARM: 7815/1: kexec: offline non panic CPUs on Kdump panic
+
+From: Vijaya Kumar K <vijay.kilari@gmail.com>
+
+commit 4f9b4fb7a2091eec339413a460b1665758401828 upstream.
+
+In case of normal kexec kernel load, all cpu's are offlined
+before calling machine_kexec().But in case crash panic cpus
+are relaxed in machine_crash_nonpanic_core() SMP function
+but not offlined.
+
+When crash kernel is loaded with kexec and on panic trigger
+machine_kexec() checks for number of cpus online.
+If more than one cpu is online machine_kexec() fails to load
+with below error
+
+kexec: error: multiple CPUs still online
+
+In machine_crash_nonpanic_core() SMP function, offline CPU
+before cpu_relax
