+ACPI Debug Output
+=================
 
 The ACPI CA, the Linux ACPI core, and some ACPI drivers can generate debug
 output.  This document describes how to use this facility.
 
 Compile-time configuration
---------------------------
+==========================
 
 ACPI debug output is globally enabled by CONFIG_ACPI_DEBUG.  If this config
 option is turned off, the debug messages are not even built into the
 kernel.
 
 Boot- and run-time configuration

+================================
 
 When CONFIG_ACPI_DEBUG=y, you can select the component and level of messages
 you're interested in.  At boot-time, use the acpi.debug_layer and
