Various keyboards have macro keys, which are intended to have user programmable actions / key-sequences bound to them. In some cases these macro keys are actually programmable in hardware, but more often they basically are just extra keys and the playback of the key-sequence is done by software running on the host. One example of keyboards with macro-keys are various "internet" / "office" keyboards have a set of so-called "Smart Keys", typically a set of 4 keys labeled "[A]" - "[D]". Another example are gaming keyboards, such as the Logitech G15 Gaming keyboard, which has 18 "G"aming keys labeled "G1" to G18", 3 keys to select macro presets labeled "M1" - "M3" and a key to start recording a macro called "MR" note that even though there us a record key everything is handled in sw on the host. Besides macro keys the G15 (and other gaming keyboards) also has a buildin LCD panel where the contents are controlled by the host. There are 5 keys directly below the LCD intended for controlling a menu shown on the LCD. The Microsoft SideWinder X6 keyboard is another gaming keyboard example, this keyboard has 30 "S"idewinder keys and a key to cycle through macro-presets. After discussion between various involved userspace people we've come to the conclusion that since these are all really just extra keys we should simply treat them as such and give them their own event-codes, see: https://github.com/libratbag/libratbag/issues/172 This commit adds the following new KEY_ defines for this: KEY_MACRO1 - KEY_MACRO30. KEY_MACRO_RECORD_START/-STOP, KEY_MACRO_PRESET_CYCLE, KEY_MACRO_PRESET1 - KEY_MACRO_PRESET3, KEY_KBD_LCD_MENU1 - KEY_KBD_LCD_MENU5. The defines leave room for adding some more LCD-menu, preset or macro keys, the maximum values above are based on the maximum values to support all currently known internet, office and gaming keyboards.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
