x86, UV: BAU tunables into a debugfs file
Make the Broadcast Assist Unit driver's nine tuning values variable by
making them accessible through a read/write debugfs file.
The file will normally be mounted as
/sys/kernel/debug/sgi_uv/bau_tunables. The tunables are kept in each
cpu's per-cpu BAU structure.
The patch also does a little name improvement, and corrects the reset of
two destination timeout counters.
