"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nACPI: processor_idle: Mark LPI enter functions as __cpuidle\n\nWhen function tracing or Kprobes is enabled, entering an ACPI Low\nPower Idle (LPI) state triggers the following RCU splat:\n\n RCU not on for: acpi_idle_lpi_enter+0x4/0xd8\n WARNING: CPU: 8 PID: 0 at include/linux/trace_recursion.h:162 function_trace_call+0x1e8/0x228\n\nThe acpi_idle_lpi_enter() function is invoked within the cpuidle\npath after RCU has already been disabled for the current local CPU.\nConsequently, ftrace's function_trace_call() expects RCU to be\nactively watching before recording trace data, emitting a warning\nif it is not.\n\nFix this by annotating acpi_idle_lpi_enter(), the generic __weak\nstub, and the RISC-V implementation of acpi_processor_ffh_lpi_enter()\nwith __cpuidle. This moves these functions into the '.cpuidle.text'\nsection, implicitly disabling ftrace instrumentation (notrace) along\nthis sensitive path and preventing trace-induced RCU warnings during\nidle entry."
