- Remove clause 3 and 4 from TNF licenses. [1]
- Add the _RF_X committed in r212998 also to the tables in the sparc64 reloc.c in order reduce differences between the kernel and the userland source. This results in no functional change though. - Fix further inconsistencies in the abbreviations of the names of the relocations. - Further whitespace fixes. Obtained from: NetBSD [1]
