88  * XXX: The internal memory tracking of ACPICA, available when
89  *      ACPI_DBG_TRACK_ALLOCATIONS is defined, has been removed
90  *      from ACPI_DEBUG.
91  *
92  *      This is due to the instability of the ABI of ACPICA.
93  *
94  *      If the memory tracking is enabled, ACPICA will insert a header
95  *      to each memory allocation. As a consequence, when ACPI specific
96  *      code is loaded as a kernel module and the running kernel has
97  *      been compiled with ACPI_DEBUG, the result is an instant panic.
98  *      This happens because of unaligned memory access when the code
99  *      tries to use ACPI_FREE for a buffer obtained via ACPI_ALLOCATE,
100  *      AcpiEvaluateObject(), and related calls.
101  *
102  *      If the involved memory statistics are required, a separate constant
103  *      ACPI_DEBUG_ALLOC is available in options(4) for ACPI_DEBUG kernels.
