Modified Files: src/sys/arch/mips/include: asm.h Log Message: mips: Redefine LLSCSYNC as empty on non-Octeon MP. This change deletes memory barriers on non-Octeon MP. However, all the appropriate acquire and release barriers are already used in mutex stubs, and no barriers are needed in atomic_* unless we set __HAVE_ATOMIC_AS_MEMBAR which we don't on MIPS. So this should be safe. Unclear whether we need this even on Octeon -- don't have a clear reference on why it's here.
