** it's not ioremapped. ** 3.add return -ENOMEM if ioremap() fails ** 4.transfer IS_SG64_ADDR w/ cpu_to_le32() ** in arcmsr_build_ccb ** 5. modify acb->devstate[i][j] as ARECA_RAID_GONE instead of ** ARECA_RAID_GOOD in arcmsr_alloc_ccb_pool() ** 6.fix arcmsr_cdb->Context as (unsigned long)arcmsr_cdb ** 7.add the checking state of ** (outbound_intstatus & ARCMSR_MU_OUTBOUND_HANDLE_INT) == 0 ** in arcmsr_handle_hba_isr ** 8.replace pci_alloc_consistent()/pci_free_consistent() with kmalloc()/kfree() in arcmsr_iop_message_xfer() ** 9. fix the release of dma memory for type B in arcmsr_free_ccb_pool() ** 10.fix the arcmsr_polling_hbb_ccbdone() ** 1.20.00.15 02/27/2008 Erich Chen & Nick Cheng ** 1.arcmsr_iop_message_xfer() is called from atomic context under the ** queuecommand scsi_host_template handler. James Bottomley pointed out ** that the current GFP_KERNEL|GFP_DMA flags are wrong: firstly we are in ** atomic context, secondly this memory is not used for DMA. ** Also removed some unneeded casts.
