Raw Normal View History

Update to upstream 20200925 version This update also means a major update for all of the big-endian patching that has been done. The older mechanism was getting to unwieldy to keep maintained, and too sensitive to upstream changes. Hence, redid all of the old patches, and took the opportunity to make them more amenable to change over time. Ultimately, the goal is to have upstream accept these in some form.
