>**						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

>** 1.20.00.15.RH   11/06/2007       Erich Chen & Nick Cheng
>**                                              This is the specific version fot RHEL5.2 exclusively.
>**						It is the variant of arcmsr.1.20.00.15 11/06/2007.
>**						1. delete pci_error_handler(), which is supported after kernel 2.6.19
>**						2.in arcmsr_build_ccb(), arcmsr_iop_message_xfer() 
>**						,arcmsr_pci_unmap_dma and arcmsr_handle_virtual_command,
>**						replace to invoke pci_map_sg 
>**						, scsi_cmnd.use_sg and scsi_cmnd.request_buffer
>**						to get the material in scatter-gather list   
>**						from upper scsi layer .
>**						3.check if the sg list member number 
>**						exceeds arcmsr default limit in arcmsr_build_ccb()
>**						4.change the returned value type of arcmsr_build_ccb()
>**						from "void" to "int"
>**						5.add the conditional check if arcmsr_build_ccb()
>**						returns FAILED
>**						This is quoted as the methodology in arcmsr.1.20.00.13.
>** 1.20.00.15.RH   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.RH   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()
