The arch_timer_reg_read_stable macro in arch/arm64/include/asm/arch_timer.h
in the Linux kernel before 4.13 allows local users to cause a denial of
service (infinite recursion) by writing to a file under /sys/kernel/debug
in certain circumstances, as demonstrated by a scenario involving debugfs,
ftrace, PREEMPT_TRACER, and FUNCTION_GRAPH_TRACER.
