      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nsoc/tegra: pmc: Fix unsafe generic_handle_irq() call\n\nCurrently, when resuming from system suspend on Tegra platforms,\nthe following warning is observed:\n\nWARNING: CPU: 0 PID: 14459 at kernel/irq/irqdesc.c:666\nCall trace:\n handle_irq_desc+0x20/0x58 (P)\n tegra186_pmc_wake_syscore_resume+0xe4/0x15c\n syscore_resume+0x3c/0xb8\n suspend_devices_and_enter+0x510/0x540\n pm_suspend+0x16c/0x1d8\n\nThe warning occurs because generic_handle_irq() is being called from\na non-interrupt context which is considered as unsafe.\n\nFix this warning by deferring generic_handle_irq() call to an IRQ work\nwhich gets executed in hard IRQ context where generic_handle_irq()\ncan be called safely.\n\nWhen PREEMPT_RT kernels are used, regular IRQ work (initialized with\ninit_irq_work) is deferred to run in per-CPU kthreads in preemptible\ncontext rather than hard IRQ context. Hence, use the IRQ_WORK_INIT_HARD\nvariant so that with PREEMPT_RT kernels, the IRQ work is processed in\nhardirq context instead of being deferred to a thread which is required\nfor calling generic_handle_irq().\n\nOn non-PREEMPT_RT kernels, both init_irq_work() and IRQ_WORK_INIT_HARD()\nexecute in IRQ context, so this change has no functional impact for\nstandard kernel configurations.\n\n[treding@nvidia.com: miscellaneous cleanups]",
