Mårten Lindahl 5590ba4560 ARM: 9317/1: kexec: Make smp stop calls asynchronous 
[ Upstream commit 8922ba71c9 ]

If a panic is triggered by a hrtimer interrupt all online cpus will be
notified and set offline. But as highlighted by commit 19dbdcb803
("smp: Warn on function calls from softirq context") this call should
not be made synchronous with disabled interrupts:

 softdog: Initiating panic
 Kernel panic - not syncing: Software Watchdog Timer expired
 WARNING: CPU: 1 PID: 0 at kernel/smp.c:753 smp_call_function_many_cond
   unwind_backtrace:
     show_stack
     dump_stack_lvl
     __warn
     warn_slowpath_fmt
     smp_call_function_many_cond
     smp_call_function
     crash_smp_send_stop.part.0
     machine_crash_shutdown
     __crash_kexec
     panic
     softdog_fire
     __hrtimer_run_queues
     hrtimer_interrupt

Make the smp call for machine_crash_nonpanic_core() asynchronous.
