[SCSI] arcmsr: initial driver, version 1.20.00.13 



arcmsr is a driver for the Areca Raid controller, a host based RAID
subsystem that speaks SCSI at the firmware level.

This patch is quite a clean up over the initial submission with

** 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
