I have an old patch that replaces hand-rolled ACPI platform primitives
with thin wrappers around the standard kernel primitives.  It covers
locks and memory allocation.
I don't recall what objections there were when I originally proposed
that change.  I still think that it is a good idea.  The kernel code has
quite a bit more testing and tooling around it than the ACPI-only things.
