The ARM EFI init code never assigns the config_table member of the efi struct, which means the sysfs device node is missing, and other in-kernel users will not work correctly. So add the missing assignment. Note that, for now, the runtime and fw_vendor members are still omitted. This is deliberate: exposing physical addresses via sysfs nodes encourages behavior that we would like to avoid on ARM (given how it is more finicky about using correct memory attributes when mapping memory in userland that may be mapped by the kernel already as well).

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.
