All macros are now replaced with inline functions, which increased the total loc again by some amount. This patchset cleans up hugetlbfs architecture headers and adds new primitives as preparation for the s390 large page support. Most notably we found that we need to add a new tlb flush for the copy-on-write of a large page (patch 2/3). We think that this is a bug, but obviously one that hasn't shown up so far on any of the other large page architectures. Cross-Compile tests on the affected architectures (and one unaffected) worked fine, but I had no cross-compiler for sh. -- Gerald Schaefer
