Tej Parkash 1b3d399cf6 [SCSI] qla4xxx: Fix processing response queue during probe
Issue:
While booting with kdump kernel, driver receive IOCB interrupts
for which it is not ready which results in processing them
before init_firmware during driver probe

Fix:
Two steps solution
1. Make driver ready to process the interrupt before interupts
   handlers is registered.
2. Stop driver processing iocb interrupts if not generated as per
   firmware protocol i.e R2H bit set

Kees Cook d8537548c9 drivers: avoid format strings in names passed to alloc_workqueue()
For the workqueue creation interfaces that do not expect format strings,
make sure they cannot accidently be parsed that way.  Additionally, clean
up calls made with a single parameter that would 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.

This fixes a bug where the iscsi class/driver did not do a put_device
when a sess/conn device was found. This also simplifies the interface
by not having to pass in some arguments that were duplicated and did
not need to be exported.

Tej Parkash a24058f9c2 [SCSI] qla4xxx: Fixed request queue count manipulation on response path
Issue:
Request queue count holds the information about free space in request queue
which has to be manipulated based on request in and out pointer.
But in driver response path, this count was incremented unconditionally,
which could move req_in pointer beyond req_out pointer.
This scenario leads fw hang during IO.

Solution:
Request queue count manipulation has to be done in IO path only, keeping
req_in and req_out pointer two IOCB count away

Manish Rangankar 3dd4849c25 [SCSI] qla4xxx: Fix memory corruption issue in qla4xxx_get_ep_fwdb.
In qla4xxx_get_ep_fwdb(), dst_addr is of type struct sockaddr.
We are copying sizeof(struct sockaddr_in6) bytes to dst_addr
which is 12 bytes larger. This will cause memory corruption.
So we change dst_addr to struct sockaddr_storage which is
of 128 byte, large enough to hold sizeof(struct sockaddr_in6).

Vikas Chaudhary 5c19b92ae8 [SCSI] qla4xxx: Fix MBOX intr switching from polling to intr mode for ISP83XX
Issue:
Mailbox command timed out after switching from polling mode to interrupt mode.

Events:-
 1. Mailbox interrupts are disabled
 2. FW generates AEN and at same time driver enables Mailbox Interrupt
 3. Driver issues new mailbox to Firmware

In above case driver will not get AEN interrupts generated by FW in step #2 as
FW generated this AEN when interrupts are disabled. During the same time
driver enabled the mailbox interrupt, so driver will not poll for interrupt.
Driver will never process AENs generated in step #2 and issues new mailbox to
FW, but now FW is not able to post mailbox completion as AENs generated before
are not processed by driver.

Fix:
Enable Mailbox / AEN interrupts before initializing FW in case of ISP83XX.
This will make sure we process all Mailbox and AENs in interrupt mode.

Greg Kroah-Hartman 6f03979051 Drivers: scsi: remove __dev* attributes.
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.

 for new 83xx based card], qla4xxx, mpt2sas, bfa, zfcp, hpsa, be2iscsi, isci,
 lpfc, ipr, ibmvfc, ibmvscsi, megaraid_sas).  There's also a rework for tape
 adding virtually unlimited numbers of tape drives plus a set of dif fixes for
 sd and a fix for a live lock on hot remove of SCSI devices.
