ACPI uses cmpxchg so it's not possible to build it for i386 it seems.

+__acpi_release_global_lock (unsigned int *lock)
+{
+       unsigned int old, new, val;
+       do {
+               old = *lock;
+               new = old & ~0x3;
+               val = cmpxchg(lock, old, new);
+       } while (unlikely (val != old));
+       return old & 0x1;
+}
