We're filling the "remainder" word with little-endian data, then writing it out to IO registers with endian-correcting writel(). That probably won't work on big-endian systems. Let's mark the "remainder" variable as LE32 (since we fill it with memcpy()) and do the swapping explicitly. Some of this function could be done more easily without memcpy(), but the unaligned "remainder" case is a little hard to do without potentially overrunning 'tx_buf', so I just applied the same solution in all cases (memcpy() + le32_to_cpu()). Tested only on a little-endian system.

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.
