** 2. modify the arcmsr_pci_slot_reset function
** 3. modify the arcmsr_pci_ers_disconnect_forepart function
** 4. modify the arcmsr_pci_ers_need_reset_forepart function
+** 1.20.00.15 09/27/2007 Erich Chen & Nick Cheng
+** 1. add arcmsr_enable_eoi_mode() on adapter Type B
+** 2. add readl(reg->iop2drv_doorbell_reg) in arcmsr_handle_hbb_isr()
+** in case of the doorbell interrupt clearance is cached
+** 1.20.00.15 10/01/2007 Erich Chen & Nick Cheng
+** 1. modify acb->devstate[i][j]
+** as ARECA_RAID_GOOD instead of
+** ARECA_RAID_GONE in arcmsr_alloc_ccb_pool
+** 1.20.00.15 11/06/2007 Erich Chen & Nick Cheng
+** 1. add conditional declaration for
+** arcmsr_pci_error_detected() and
+** arcmsr_pci_slot_reset
+** 1.20.00.15 11/23/2007 Erich Chen & Nick Cheng
+** 1.check if the sg list member number
+** exceeds arcmsr default limit in arcmsr_build_ccb()
+** 2.change the returned value type of arcmsr_build_ccb()
+** from "void" to "int"
+** 3.add the conditional check if arcmsr_build_ccb()
+** returns FAILED
+** 1.20.00.15 12/04/2007 Erich Chen & Nick Cheng
+** 1. modify arcmsr_drain_donequeue() to ignore unknown
+** command and let kernel process command timeout.
+** This could handle IO request violating max. segments
+** while Linux XFS over DM-CRYPT.
+** Thanks to Milan Broz's comments <mbroz@redhat.com>
+** 1.20.00.15 12/24/2007 Erich Chen & Nick Cheng
+** 1.fix the portability problems
+** 2.fix type B where we should _not_ iounmap() acb->pmu;
+** 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()
