mainlining shenanigans
905dbf1d39
Because of errata i689 the keyboard can idle with state where no key up interrupts are seen until after the next key press. This means we need to first check for any lost key up events before scanning for new down events. For example, rapidly pressing shift-shift-j can sometimes produce a J instead of j. Let's fix the issue by scanning the keyboard in two phases. First we scan for any key up events that we may have missed, and then we scan for key down events. Let's also simplify things with for_each_set_bit() as suggested by Dmitry Torokhov <dmitry.torokhov@gmail.com>.

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.
