+ /* Requirements for changing the default keymaps:
+ *
+ * 1. Many of the keys are mapped to KEY_RESERVED for very
+ * good reasons. Do not change them unless you have deep
+ * knowledge on the IBM and Lenovo ThinkPad firmware for
+ * the various ThinkPad models. The driver behaves
+ * differently for KEY_RESERVED: such keys have their
+ * hot key mask *unset* in mask_recommended, and also
+ * in the initial hot key mask programmed into the
+ * firmware at driver load time, which means the firm-
+ * ware may react very differently if you change them to
+ * something else;
+ *
+ * 2. You must be subscribed to the linux-thinkpad and
+ * ibm-acpi-devel mailing lists, and you should read the
+ * list archives since 2007 if you want to change the
+ * keymaps. This requirement exists so that you will
+ * know the past history of problems with the thinkpad-
+ * acpi driver keymaps, and also that you will be
+ * listening to any bug reports;
+ *
+ * 3. Do not send thinkpad-acpi specific patches directly to
+ * for merging, *ever*. Send them to the linux-acpi
+ * mailinglist for comments. Merging is to be done only
+ * through acpi-test and the ACPI maintainer.
+ *
+ * If the above is too much to ask, don't change the keymap.
+ * Ask the thinkpad-acpi maintainer to do it, instead.
