This patch mostly checks out. But see below.

Nit: Use lowercase for '0xC' to be consistent.

I recently saw a review comment stating one should not inline functions
unless they are defined in header files. Otherwise the decision should
be left up to the compiler.

This one as well.

This is the only instance where a function's "layer" parameter was changed
to "base". It would be nice if it were consistent.
