The code using it should ever be referenced on uni-processor systems that don't have ll/sc and on those the spinlock code happens to not reference the spinlock_t argument not at all. So iow if the compiled code actually references atomic_lock, something is smelling. In general the reason is not having an include/asm-mips/mach-<foo>/cpu-feature-overrides.h file. If this is missing the kernel will fallback to runtime detection of cpu_has_llsc which due to the performance sensitive nature of most atomic_t users is a bad idea. So this error is the bomb hidden in the code to alert users ... Ralf
