    "summary": "In the Linux kernel, the following vulnerability has been resolved: LoongArch: Fix warnings during S3 suspend The enable_gpe_wakeup() function calls acpi_enable_all_wakeup_gpes(), and the later one may call the preempt_schedule_common() function, resulting in a thread switch and causing the CPU to be in an interrupt enabled state after the enable_gpe_wakeup() function returns, leading to the warnings as follow.
