New Revision: 219940
URL: http://svn.freebsd.org/changeset/base/219940
Log:
MFC: r219339, r219532
- Remove clause 3 and 4 from TNF licenses. [1]
- Add the _RF_X committed in r212998 (merged to stable/8 in r213478) 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.
- Consistently abbreviate the names of the relocations.
- End sentences with dots.
- Fix whitespace.
