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.

29dd3609f2 [SCSI] mpt fusion: standardize printks and debug info
Standardize all prints using common MYIOC_s_XXX_FMT macro defined in mptbase.h. Currently the driver uses several different methods to display info, where in some cases the "controller name" generating the printk is not provided.

fa027c2a0a [PATCH] mark struct file_operations const 4
Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

This utilizes the hostdata area that is hung off of scsi_target and

This also fixs problems in error handling error code for SAS
controllers, in which the incorrect mapping was passed to the
firmware.

733482e445 [PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reason
This patch removes almost all inclusions of linux/version.h.  The 3
#defines are unused in most of the touched files.

A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
unfortunatly in linux/version.h.

There are also lots of #ifdef for long obsolete kernels, this was not
touched.  In a few places, the linux/version.h include was move to where
the LINUX_VERSION_CODE was used.

quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'`

466544d889 [SCSI] fusion SAS support (mptsas driver) updates
Summary of Changes:
* splitting mpt_interrupt per Christophs suggestion
about a month ago
* rename ScsiCfgData to SpiCfgData structure,
then move all the raid related info into
new structure called RaidCfgData.  This is
done because SAS supports RAID, as well as SPI,
so the raid stuff should be seperate.
* incorrect timeout calculation for cntdn
inside WaitForDoorbellAck and WaitForDoortbellInt
* add support for interpreting SAS Log Info
* Increase Event Log Size from 0xA to 0x32
* Fix bug in mptsas/mptfc/mptspi - when controller
has Initiator Mode Disabled, and only running in
TargetMode, the mptctl would panic when loading.
The fix is to return 0, instead of -ENODEV, in
SCSI LLD respective probe routines
* Fix bug in mptlan.c - driver will panic if
there is host reset, due to dev being set to
zero in mpt_lan_ioc_reset
* Fix's for SPI - Echo Buffer
* Several fix's in mptscsih_io_done - FCP Response
info, RESIDUAL_MISMATCH, Data Underrun, etc.
* Cleanup Error Handling - EH handlers,
mptscsih_flush_cmds, and zeroing out ScsiLookup
from mptscsih_qcmd
* Cleanup asyn event handling from
mptscsih -> mptscsih_event_process.  Also
added support for SAS Persistent Table Full,
an asyn event

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
