However, for the PE stub entry case, we can request that the EFI PE/COFF loader do the work for us. Fix by exposing the desired alignment via the SectionAlignment field in the PE/COFF headers. Despite its name, this field provides an overall alignment requirement for the loaded file. (Naturally, the FileAlignment field describes the alignment for individual sections.) There is no way in the PE/COFF headers to express the concept of min_alignment; we therefore do not expose the minimum (as opposed to preferred) alignment.
