A DABT is reported[1] on an android based system when resume from hiberate,
which is root caused as CFI will plant stub code[2] to verify the
swsusp_arch_suspend_exit's authentication, where the hash value is stored
before the page that alloced by create_safe_exec_page. We also have
tried to copy the hash value together with the function but get failed since
the value is not on the desired position(src_start - 4). So we solve
this issue by setting __nocfi on swsusp_arch_resume and it works.
