Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux

There are situations where adding padding to the front and back of an Rx buffer will require that we add additional padding. Specifically if NET_IP_ALIGN is non-zero, or the MTU size is larger than 7.5K we would need to use 2K buffers which leaves us with no room for the padding. To preemptively address these cases I am adding support for 3K buffers to the Rx path so that we can provide the additional padding needed in the event of NET_IP_ALIGN being non-zero or a cache line being greater than 64.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
