+ * 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

+ *
+ *      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.
