- * Inline code for use of the ll and sc instructions
- *
- * FIXME: This instruction is only available on MIPS ISA >=2.
- * Since these operations are only being used for atomic operations
- * the easiest workaround for the R[23]00 is to disable interrupts.
- * This fails for R3000 SMP machines which use that many different
- * technologies as replacement that it is difficult to create even
- * just a hook for for all machines to hook into.  The only good
- * thing is that there is currently no R3000 SMP machine on the
- * Linux/MIPS target list ...
