Tony Jones ee959b00c3 SCSI: convert struct class_device to struct device
It's big, but there doesn't seem to be a way to split it up smaller...

nickcheng 4d3995b14b [SCSI] arcmsr: fix iounmap error for Type B adapter
The Type B Adapter teardown does iounmap on pointers subtracted by a
constant offset.  Since the offset is in bytes, we need the pointers to
be of type void * not uint32_t * so the subtraction is done in the
correct units and we iounmap the correct area.

Nick Cheng 76d78300a6 [SCSI] arcmsr: updates (1.20.00.15)
- add arcmsr_enable_eoi_mode()and readl(reg->iop2drv_doorbell_reg) in
  arcmsr_handle_hbb_isr() on adapter Type B in case of the doorbell
  interrupt clearance is cached

- add conditional declaration for arcmsr_pci_error_detected() and
  arcmsr_pci_slot_reset

- check if the sg list member number exceeds arcmsr default limit in
  arcmsr_build_ccb()

- change the returned value type of arcmsr_build_ccb()from "void" to
  "int" returns FAILED in arcmsr_queue_command()

- modify arcmsr_drain_donequeue() to ignore unknown command and let
  kernel process command timeout.  This could handle IO request violating
  maximum segments, i.e.  Linux XFS over DM-CRYPT.  Thanks to Milan Broz's
  comments <mbroz@redhat.com>

- fix the release of dma memory for type B in arcmsr_free_ccb_pool()

- fix the arcmsr_polling_hbb_ccbdone()

Al Viro db3a91fe2b deal with resource allocation bugs in arcmsr
a) for type B we should _not_ iounmap() acb->pmu; it's not ioremapped.
b) for type B we should iounmap() two regions we _do_ ioremap.
c) if ioremap() fails, we need to bail out (and clean up).

nickcheng(鄭守謙 a1f6e0211b [SCSI] areca: improve driver stability and compatibility
Description:

    1. Implement PCI-Express error recovery function and AER
       capability, especially thanks to Yanmin Zhang's openhanded help
       about AER

    2. Implement the selection of ARCMSR_MAX_XFER_SECTORS_B=4096 if
       firmware version is latter than 1.42

    3. Add arcmsr_done4_abort_postqueue in arcmsr_iop_reset function
       to improve the stability as hot-unplug/plug

    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 midlayer
