Alan Cox 9d793b0bcb i2o: Fix 32/64bit DMA locking
The I2O ioctls assume 32bits.  In itself that is fine as they are old
cards and nobody uses 64bit.  However on LKML it was noted this
assumption is also made for allocated memory and is unsafe on 64bit
systems.

Fixing this is a mess.  It turns out there is tons of crap buried in a
header file that does racy 32/64bit filtering on the masks.

So we:
- Verify all callers of the racy code can sleep (i2o_dma_[re]alloc)
- Move the code into a new i2o/memory.c file
- Remove the gfp_mask argument so nobody can try and misuse the function
- Wrap a mutex around the problem area (a single mutex is easy to do and
  none of this is performance relevant)
- Switch the remaining problem kmalloc holdout to use i2o_dma_alloc

Wang Chen 0293902a4d I2O: handle sysfs_create_link() failures
Compile warning:
ignoring return value of `sysfs_create_link', declared with attribute warn_unused_result.

If sysfs_create_link failed, take care of the return value and do some
error handle after the failure.

Since sysfs_remove_link() will check whether a link exists, when removing the
link in error path, we don't need to care whether a link was created.

James Bottomley 2789898817 [SCSI] fusion: default MSI to disabled for SPI and FC controllers
There's a fault on the FC controllers that makes them not respond
correctly to MSI.  The SPI controllers are fine, but are likely to be
onboard on older motherboards which don't handle MSI correctly, so
default both these cases to disabled.  Enable by setting the module
parameter mpt_msi_enable=1.

For the SAS case, enable MSI by default, but it can be disabled by
setting the module parameter mpt_msi_enable=0.

The problem here is that if the ioc faults too early in the bring up
sequence (as it usually does for an irq routing problem), ioc_reset gets
called before the scsi host is even allocated.  This causes an oops when
it later schedules a renegotiation.  Fix this by checking ioc->sh before
trying to renegotiate.

Michael Reed 7ba2db5f38 [SCSI] fusion mpt: fix target missing after resetting external raid
Following a hard reset of a SAS raid, one of the raid targets is occasionally
missing.  I tracked this down to a pretty obscure little bug.

The LSI fusion drivers for SAS and Fibre Channel both use their respective
transport layers.  Those transport layers increment the target number
assigned to new targets.

The routine __scsi_scan_target uses the "this_id" element of the Scsi_Host
structure to avoid scanning the scsi host adapter.  Both fusion drivers set
"this_id" from a value returned in a firmware PortFacts response.  For my
particular test case (SAS) the firmware id assigned to the initiator was
173.  After enough raid resets to cause the raid targets to go and come a
sufficient number of times, the id assigned by the transport to a raid
target would match the id assigned by the host adapter to the "this_id"
field, resulting in that target not being scanned.

Fix by not assigning this_id and not checking it in slave_configure.

Michael Reed 7748369f49 [SCSI] mptsas: do not use ioc->handle to locate hba portinfo structure
While performing hardware raid reset testing via the raid's client, I
noticed that sometimes, following the reset, that there would be more
raid targets in the lsscsi output than there actually were raid
targets.  I tracked this down to the following issue.

Fusion cannot always find the mptsas_portinfo structure for the hba
because it uses the handle stored in ioc->handle to locate it.  The
problem is that the firmware can change the handle associated with the
hba when h/w raid is reset (via the raid client).  When this happens,
the driver will allocate another mptsas_portinfo structure and link it
into the chain of said structures.  This ultimately causes confusion
within the driver resulting in targets not being removed when they
should be.

Eric Moore pointed out that the hba's portinfo structure is always the
first structure on the sas_topology list.  This patch modifies
mptsas.c to access the hba's portinfo structure by taking the first
structure on said list.

Satyam Sharma c98673fee2 I2O: Fix "defined but not used" build warnings
drivers/message/i2o/exec-osm.c:539: warning: `i2o_exec_lct_notify' defined but not used

comes when CONFIG_I2O_LCT_NOTIFY_ON_CHANGES=n, because its only callsite
is #ifdef'ed as such. So let's #ifdef the function definition also. Also
move the definition to before the callsite, to get rid of forward prototype.

Eric Moore ab37128797 [SCSI] mptctl : shutup uninitialized variable warnings
drivers/message/fusion/mptctl.c: In function ‘mptctl_mpt_command’:
drivers/message/fusion/mptctl.c:1764: warning: ‘bufIn.len’ may be used uninitialized in this function
drivers/message/fusion/mptctl.c:1765: warning: ‘bufOut.len’ may be used uninitialized in this function

come because gcc gets confused by some "goto" statements in above
function.  The warnings have been verified to be bogus, however, the
function does initialize these later (after the offending goto's) in
the function anyway.  So let's move those initializations to top of
function, thereby also shutting up these warnings.

Eric Moore e1fc2b5167 [SCSI] mptlan: bug fix, only half the message frame is dma'd resulting in corruption
NB = number of blocks.  This represents the number of blocks to
transfer.  The block size is based on the message frame size provided
in the ioc_facts. A value of zero indicates the entire message frame
should be copied. This is two bit value.  So by setting this to
non-zero vaule, you increase performance by reducing amount of data
needing to be dma'd.  The value that is stored in ioc->ReqeustNB is
sometimes a non-zero vaule, which creates a bug in mptlan, where not
the entire message frame is getting transfer to firware, resulting in
corruption.  This fix sets the default to zero, thus entire message
frame is copied.
