Change all _hw_dmar to _hw_iommu
- rS363534: o Make the _hw_iommu sysctl node non-static;
Boot on amd64
Unit Tests Skipped
Mmm, I think the node should be declared unconditionally, regardless of the INVARIANTS build. Also I remember that nodes should be RW if any mib below them is rw.
This should not link in non-INVARIANTS kernels.
Also, I asked to put dmar-specific mibs under hw.iommu.dmar.
I mean that for non-INVARIANTS kernels the node (or whatever, I do not remember already) was defined only under INVARIANTS (i.e. nowhere), while declared and used. Then linker should compain about undefined symbol.
