      [SCSI] mpt fusion: rewrite of all internal generated functions · 37c60f37
      由 Kashyap, Desai 提交于 
      Rewrite of all internal generated functions that issue commands to firmware,
porting them to be single threaded using the generic MPT_MGMT
struct. Implemented using completion Queue.

      [SCSI] mpt fusion: Fixing 1078 data corruption issue for 36GB memory region · 14d0f0b0
      由 Kashyap, Desai 提交于 
      The reason for this change is there is a data corruption when four different
physical memory regions in the 36GB to 37GB region are
accessed. This is only affecting 1078.

The solution is we need to use different addressing when filling in
the scatter gather table for the effected memory regions.  So instead
of snooping on all four different memory holes, we treat any physical
addresses in the 36GB address with the same algorithm.

The fix is explained below
1) Ensure that the message frames are NOT located in the trouble
region. There is no remapping available for message frames, they must
be allocated outside the problem region.
2) Ensure that Sense buffers are NOT in the trouble region. There is
no remapping available.
3) Walk through the SGE entries and if any are inside the trouble region
   then they need to be remapped as discussed below.
	1) Set the Local Address bit in the SGE Flags field.
  	MPI_SGE_FLAGS_LOCAL_ADDRESS
  	2) Ensure we are using 64-bit SGEs
  	3) Set MSb (Bit 63) of the 64-bit address, this will indicate buffer
	location is Host Memory.

      [SCSI] fusion: fix domain validation loops · 72978245
      由 Eric Moore 提交于 
      After host reset, the device are programmed to default asyn narrow nego.
We need to reprogram the parameter back to previous values.  If the host
reset is called as a result of spi_dv_device() commands timing out, its
possible to get into an infinite loop of dv to host reset.  This will
prevent that case, as we merely program old values.  If host reset is
called outside context of domain validation, then we can  call
spi_dv_device.

      [PATCH] remove many unneeded #includes of sched.h · cd354f1a
      由 Tim Schmielau 提交于 
      After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

      [SCSI] mptspi: Add transport class Domain Validation · c92f222e
      由 James Bottomley 提交于 
      This is the first half of a patch to add the generic domain validation
to mptspi.  It also creates a secondary "virtual" channel for raid
component devices since these are now exported with no_uld_attach.

What Eric and I would have really liked is to export all physical
components on channel 0 and all raid components on channel 1.
Unfortunately, this would result in device renumbering on platforms with
mixed RAID/Physical devices which was considered unacceptable for
userland stability reasons.

Still to be done is to plug back the extra parameter setting and DV
pieces on reset and hotplug.
