Modified Files: src/sys/arch/alpha/alpha: cpu.c Log Message: alpha: Fix placement of membar for sending ICCB message. While here, reduce it to membar_exit -- it's obviously not needed for store-before-load here (although alpha doesn't have anything weaker than the full sequential consistency `mb'), and although we do need a store-before-load (and load-before-load) to spin waiting for the CPU to wake up, that already happens a few lines below with alpha_mb in the loop anyway. So no need for membar_sync, which is just `mb' under the hood -- deleting the membar_sync in this place can't hurt. The membar_sync had been inserted automatically when converting from an older style of atomic_ops(3) API.
