Description		In the Linux kernel, the following vulnerability has been resolved: perf/amlogic: Replace smp_processor_id() with raw_smp_processor_id() in meson_ddr_pmu_create() The Amlogic DDR PMU driver meson_ddr_pmu_create() function incorrectly uses smp_processor_id(), which assumes disabled preemption. This leads to kernel warnings during module loading because meson_ddr_pmu_create() can be called in a preemptible context.

La funci\u00f3n meson_ddr_pmu_create() del controlador PMU DDR de Amlogic utiliza incorrectamente smp_processor_id(), que presupone la preempci\u00f3n deshabilitada. Esto genera advertencias del kernel durante la carga del m\u00f3dulo, ya que meson_ddr_pmu_create() puede invocarse en un contexto preemptible.
