+** 1.20.00.06    3/12/2005       Erich Chen     fix with arcmsr_pci_unmap_dma "unsigned long" cast,
+**						modify PCCB POOL allocated by "dma_alloc_coherent"
+**						(Kornel Wieliczek's comment)
+** 1.20.00.07    3/23/2005       Erich Chen     bug fix with arcmsr_scsi_host_template_init
+**						occur segmentation fault,
+**						if RAID adapter does not on PCI slot
+**						and modprobe/rmmod this driver twice.
+**						bug fix enormous stack usage (Adrian Bunk's comment)
+** 1.20.00.08    6/23/2005       Erich Chen     bug fix with abort command,
+**						in case of heavy loading when sata cable
+**						working on low quality connection
+** 1.20.00.09    9/12/2005       Erich Chen     bug fix with abort command handling, firmware version check
+**						and firmware update notify for hardware bug fix
+** 1.20.00.10    9/23/2005       Erich Chen     enhance sysfs function for change driver's max tag Q number.
+**						add DMA_64BIT_MASK for backward compatible with all 2.6.x
+**						add some useful message for abort command
+**						add ioctl code 'ARCMSR_IOCTL_FLUSH_ADAPTER_CACHE'
+**						customer can send this command for sync raid volume data
+** 1.20.00.11    9/29/2005       Erich Chen     by comment of Arjan van de Ven fix incorrect msleep redefine
+**						cast off sizeof(dma_addr_t) condition for 64bit pci_set_dma_mask
+** 1.20.00.12    9/30/2005       Erich Chen     bug fix with 64bit platform's ccbs using if over 4G system memory
+**						change 64bit pci_set_consistent_dma_mask into 32bit
+**						increcct adapter count if adapter initialize fail.
+**						miss edit at arcmsr_build_ccb....
+**						psge += sizeof(struct _SG64ENTRY *) =>
+**						psge += sizeof(struct _SG64ENTRY)
+**						64 bits sg entry would be incorrectly calculated
+**						thanks Kornel Wieliczek give me kindly notify
+**						and detail description
+** 1.20.00.13   11/15/2005       Erich Chen     scheduling pending ccb with FIFO
+**						change the architecture of arcmsr command queue list
+**						for linux standard list
+**						enable usage of pci message signal interrupt
+**						follow Randy.Danlup kindness suggestion cleanup this code
+** 1.20.00.14   05/02/2007	 Erich Chen & Nick Cheng
+**						1.implement PCI-Express error recovery function and AER capability
+**						2.implement the selection of ARCMSR_MAX_XFER_SECTORS_B=4096
+**				 		if firmware version is newer than 1.42
+**						3.modify arcmsr_iop_reset to improve the ability
+**						4.modify the ISR, arcmsr_interrupt routine,to prevent the
+**						inconsistency with sg_mod driver if application	directly calls
+**						the arcmsr driver w/o passing through scsi mid layer
+**						specially thanks to Yanmin Zhang's openhanded help about AER
+** 1.20.00.15   08/30/2007	 Erich Chen & Nick Cheng
+**						1. support ARC1200/1201/1202 SATA RAID adapter, which is named
+**						ACB_ADAPTER_TYPE_B
+**						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()
+**						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. Thanks to Daniel Drake <dsd@gentoo.org>
