Descriptions

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

soc: fsl: qbman: Always disable interrupts when taking cgr_lock

smp_call_function_single disables IRQs when executing the callback. To
prevent deadlocks, we must disable IRQs when taking cgr_lock elsewhere.
This is already done by qman_update_cgr and qman_delete_cgr; fix the
other lockers.

En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: soc:fsl:qbman: Desactiva siempre las interrupciones al tomar cgr_lock smp_call_function_single desactiva las IRQ al ejecutar la devolución de llamada. Para evitar interbloqueos, debemos desactivar las IRQ cuando llevemos cgr_lock a otro lugar. Esto ya lo hacen qman_update_cgr y qman_delete_cgr; arreglar los otros casilleros.
