In the Linux kernel, the following vulnerability has been resolved:

drivers/perf: Fix ali_drw_pmu driver interrupt status clearing

The alibaba_uncore_pmu driver forgot to clear all interrupt status
in the interrupt processing function. After the PMU counter overflow
interrupt occurred, an interrupt storm occurred, causing the system
to hang.

Therefore, clear the correct interrupt status in the interrupt handling
function to fix it.
