APPLIED: [PATCH] [Trusty/Utopic] UBUNTU: SAUCE: (no-up) arm64: optimized copy_to_user and copy_from_user assembly code

[Tim Gardner]

Though this patch is essentially un-reviewable unless one is an arm64
architecture expert, test results are positive and upstream discussion
is favorable. Applied until (or if) regressions are detected.
