Provide a __copy_from_user that uses memcpy. On BCM2708, use optimised memcpy/memmove/memcmp/memset implementations. arch/arm: Add mmiocpy/set aliases for memcpy/set See: https://github.com/raspberrypi/linux/issues/1082 copy_from_user: CPU_SW_DOMAIN_PAN compatibility The downstream copy_from_user acceleration must also play nice with CONFIG_CPU_SW_DOMAIN_PAN.

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.
