/*
 * XXX: The internal memory tracking of ACPICA, available when
 *      ACPI_DBG_TRACK_ALLOCATIONS is defined, has been removed
 *      from ACPI_DEBUG.
 *
 *      This is due to the instability of the ABI of ACPICA.
 *
 *      If the memory tracking is enabled, ACPICA will insert a header
 *      to each memory allocation. As a consequence, when ACPI specific
 *      code is loaded as a kernel module and the running kernel has
 *      been compiled with ACPI_DEBUG, the result is an instant panic.
 *      This happens because of unaligned memory access when the code
 *      tries to use ACPI_FREE for a buffer obtained via ACPI_ALLOCATE,
 *      AcpiEvaluateObject(), and related calls.
 *
 *      If the involved memory statistics are required, a separate constant
 *      ACPI_DEBUG_ALLOC is available in options(4) for ACPI_DEBUG kernels.
