BugLink: https://bugs.launchpad.net/bugs/2120812 [ Upstream commit eedf3e3c2f2af55dca42b0ea81dffb808211d269 ] ACPICA commit 1c28da2242783579d59767617121035dafba18c3 This was originally done in NetBSD: NetBSD/src@b69d1ac and is the correct alternative to the smattering of `memcpy`s I previously contributed to this repository.
