6 /* These are here in an effort to more fully work around
7 * Spitfire Errata #51. Essentially, if a memory barrier
8 * occurs soon after a mispredicted branch, the chip can stop
9 * executing instructions until a trap occurs. Therefore, if
10 * interrupts are disabled, the chip can hang forever.
11 *
12 * It used to be believed that the memory barrier had to be
13 * right in the delay slot, but a case has been traced
14 * recently wherein the memory barrier was one instruction
15 * after the branch delay slot and the chip still hung. The
16 * offending sequence was the following in sym_wakeup_done()
17 * of the sym53c8xx_2 driver:
18 *
19 * call sym_ccb_from_dsa, 0
20 * movge %icc, 0, %l0
21 * brz,pn %o0, .LL1303
22 * mov %o0, %l2
23 * membar #LoadLoad
24 *
25 * The branch has to be mispredicted for the bug to occur.
26 * Therefore, we put the memory barrier explicitly into a
27 * "branch always, predicted taken" delay slot to avoid the
28 * problem case.
