## Description

In the Linux kernel, the following vulnerability has been resolved:  ARM: 9317/1: kexec: Make smp stop calls asynchronous  If a panic is triggered by a hrtimer interrupt all online cpus will be notified and set offline. But as highlighted by commit 19dbdcb8039c ("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.
