PD#SWPL-7676
Problem:
If we open kasan on 32bit kernel, after resume we usually will
get a stack-out-of-bounds KASAN error report. But infact that's
a fake report. Because On arm architecture, cpu suspend/resume
routine is done in function call path:
cpu_suspend -> psci_cpu_suspend -> __invoke_psci_fn_smc
during this call path, some parts of stack will be marked as
shadow memory. But when cpu resume from smc call, it directly
return to point which saved in cpu_suspend and call resume
procedure. Which do not comeback as a reverse return path:
__invoke_psci_fn_smc -> psci_cpu_suspend -> cpu_suspend
So some residual shadow memory may affect KASAN report when
cpu is calling resume hooks.
Solution:
We just need to clear all shadow in stack for this case.
