It's a NOOP since 2.6.35 and it will be removed one day.

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.

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 Async. (performance) mode support added
- New scatter/gather list format for Series 7
- Driver converts s/g list to a firmware suitable list for best performance on
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

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.

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.

The patch 116046127d1a3bad2853d02781ad9fee33f05e5a "[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.

Added Sync. mode to support Series 7/8/9 controller families: This is a
compatibility mode for all these controller families. The Async. (Performance)
mode can be changed in the future. First Async. mode version added for Series
7; Controller parameter aac_sync_mode added

It was pointed out by 'make versioncheck' that some includes of
linux/version.h are not needed in drivers/scsi/.

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
