ACPICA commit 76658f55d8cc498a763bdb92f8e0d934822a129c
For the objects that are created by default (_GPE, _SB_, etc)
there is no need to use the heavyweight ns_lookup function.
Instead, simply create each object and link it in as the namespace
is built.

ACPICA commit 1ca34b1a7b960ef321eae5dcddfff77707c88aef
There have been several places that has been calling functions
regarding module level code blocks. This change removes all old
vestiges in the codebase. This is dead code.
