Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

2013-07-04T19:30:30+00:00

Pull first round of SCSI updates from James Bottomley:
 "The patch set is mostly driver updates (usf, zfcp, lpfc, mpt2sas,
  megaraid_sas, bfa, ipr) and a few bug fixes.  Also of note is that the
  Buslogic driver has been rewritten to a better coding style and 64 bit
  support added.  We also removed the libsas limitation on 16 bytes for
  the command size (currently no drivers make use of this)"

drivers: avoid parsing names as kthread_run() format strings

2013-07-03T23:07:41+00:00

Calling kthread_run with a single name parameter causes it to be handled
as a format string. Many callers are passing potentially dynamic string
content, so use "%s" in those cases to avoid any potential accidents.

[SCSI] aacraid: Fix for arrays are going offline in the system. System hangs

2013-06-27T01:01:42+00:00

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.

[SCSI] aacraid: suppress two GCC warnings

2013-02-24T09:38:10+00:00

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.

Drivers: scsi: remove __dev* attributes.

2013-01-03T23:57:01+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

[SCSI] aacraid: Series 7 Async. (performance) mode support

2012-07-20T07:59:04+00:00

- 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
