LoongArch: Only call get_timer_irq() once in constant_clockevent_init()
来源: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
LoongArch: Only call get_timer_irq() once in constant_clockevent_init()
Under CONFIG_DEBUG_ATOMIC_SLEEP=y and CONFIG_DEBUG_PREEMPT=y, we can see
the following messages on LoongArch, this is because using might_sleep()
in preemption disable context.

Here are the complete call chains:
smpboot_entry()
start_secondary()
constant_clockevent_init()
get_timer_irq()
irq_find_matching_fwnode()
irq_find_matching_fwspec()
mutex_lock()
might_sleep()
__might_sleep()
__might_resched()
In order to avoid the above issue, we should break the call chains,
using timer_irq_installed variable as check condition to only call
get_timer_irq() once in constant_clockevent_init() is a simple and
proper way.
