Your changelog does not explain why change it. Using inline asm is
definitely the preferred way to defined the __raw_* helpers, so it
would be better not to change that aspect, same as for the arm64
patch.

The other simplifications look good to me, those are the bits we
definitely want to have common between architectures as much as
possible.
