[SCSI] arcmsr: fix message allocation

2008-02-22T15:08:13+00:00

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.

[SCSI] arcmsr: updates (1.20.00.15)

2008-02-08T00:02:44+00:00

- 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 

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

- fix the arcmsr_polling_hbb_ccbdone()

[SCSI] remove use_sg_chaining

2008-01-30T19:14:02+00:00

With the sg table code, every SCSI driver is now either chain capable
or broken (or has sg_tablesize set so chaining is never activated), so
there's no need to have a check in the host template.

Also tidy up the code by moving the scatterlist size defines into the
SCSI includes and permit the last entry of the scatterlist pools not
to be a power of two.

[SCSI] replace sizeof sense_buffer with SCSI_SENSE_BUFFERSIZE

2008-01-23T17:29:27+00:00

This replaces sizeof sense_buffer with SCSI_SENSE_BUFFERSIZE in
several LLDs. It's a preparation for the future changes to remove
sense_buffer array in scsi_cmnd structure.

deal with resource allocation bugs in arcmsr

2007-10-29T14:41:33+00:00

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).

arcmsr: endianness bug

2007-10-29T14:41:33+00:00

initializing a field in data shared with the card with
cpu_to_le32(something) | 0x100000 is broken - the field is, indeed,
little-endian and we need cpu_to_le32() on both parts.

[SCSI] add use_sg_chaining option to scsi_host_template

2007-10-16T09:24:32+00:00

This option is true if a low-level driver can support sg
chaining. This will be removed eventually when all the drivers are
converted to support sg chaining. q->max_phys_segments is set to
SCSI_MAX_SG_SEGMENTS if false.
