This enables support for gUSA (general UserSpace Atomicity).
This is the default implementation for both UP and non-ll/sc
CPUs, and is used by the libc, amongst others.
For additional information, design information can be found
in <http://lc.linux.or.jp/lc2002/papers/niibe0919p.pdf>.
This should only be disabled for special cases where alternate
