c5bebd829d [SCSI] aacraid: Fix for arrays are going offline in the system. System hangs
One of the customer had reported that the set of raid logical arrays will
become unavailable (I/O offline) after a long hours of IO stress test.  The OS
wouldn`t be accessible afterwards and require a hard reset.

This driver patch has a fix for race condition between the doorbell and the
circular buffer. The driver is modified to do an extra read after clearing the
doorbell in case there had been a completion posted during the small timing
window.

With this fix, we ran IO stress for ~13 days. There were no IO failures.

98f99a8ac8 [SCSI] aacraid: suppress two GCC warnings
Building src.o for a 32 bit system triggers two GCC warnings:
    drivers/scsi/aacraid/src.c: In function ‘aac_src_deliver_message’:
    drivers/scsi/aacraid/src.c:410:3: warning: right shift count >= width of type [enabled by default]
    drivers/scsi/aacraid/src.c:434:2: warning: right shift count >= width of type [enabled by default]

These warnings are caused by a right shift of 32. Use upper_32_bits() to
suppress them.

  Series 7, this can be disabled with driver parameter "aac_convert_sgl" for
  testing purposes
- New container read/write command structure for Series 7
- Fast response support for the SCSI pass-through path added
- Async. status response buffer changes

b5f1758f22 [SCSI] aacraid: Fix endian issues in core and SRC portions of driver
This may not fix all endian issues in this driver, but it does get the
driver working on PowerPC for a PMC SRC card. So it should at least fix
all the problems in the core and in the SRC support.

ff08784b41 [SCSI] aacraid: Use resource_size_t for IO mem pointers and offsets
This also stops using the "legacy crap" in Scsi_Host (shost->base is an
unsigned long).

This affected 32-bit systems that have 64-bit resource sizes, causing the
IO address to be truncated.

7155250574 [SCSI] aacraid: add an iounmap call to aac_src_ioremap
The patch 116046127d "[SCSI] aacraid: Added
Sync.mode to support series 7/8/9 controllers" removed an iounmap call from
aac_src_ioremap. Before that, the iounmap has been called twice with the same
value (dev->base and dev->regs.src.bar0) and the iounmap complained about it
(iounmap: bad address ...).

The proper solution is a change the paremeter from bar0 to bar1.
Fix this by adding a an iounmap(dev->regs.src.bar1) call.

e8b12f0fb8 [SCSI] aacraid: Add new code for PMC-Sierra's SRC based controller family
Added new hardware device 0x28b interface for PMC-Sierra's SRC based
controller family.

- new src.c file for 0x28b specific functions
- new XPORT header required
- sync. command interface: doorbell bits shifted (SRC_ODR_SHIFT, SRC_IDR_SHIFT)
- async. Interface: different inbound queue handling, no outbound I2O
  queue available, using doorbell ("PmDoorBellResponseSent") and
  response buffer on the host ("host_rrq") for status
- changed AIF (adapter initiated FIBs) interface: "DoorBellAifPending"
  bit to inform about pending AIF, "AifRequest" command to read AIF,
  "NoMoreAifDataAvailable" to mark the end of the AIFs
