- * Spitfire Errata #51. Essentially, if a memory barrier
- * occurs soon after a mispredicted branch, the chip can stop
- * executing instructions until a trap occurs. Therefore, if
- * interrupts are disabled, the chip can hang forever.
- *
- * It used to be believed that the memory barrier had to be
- * right in the delay slot, but a case has been traced
- * recently wherein the memory barrier was one instruction
- * after the branch delay slot and the chip still hung. The
- * offending sequence was the following in sym_wakeup_done()
- * of the sym53c8xx_2 driver:
- *
- * call sym_ccb_from_dsa, 0
- * movge %icc, 0, %l0
- * brz,pn %o0, .LL1303
- * mov %o0, %l2
- * membar #LoadLoad
- *
- * The branch has to be mispredicted for the bug to occur.
- * Therefore, we put the memory barrier explicitly into a
- * "branch always, predicted taken" delay slot to avoid the
- * problem case.
