a51fd47f1b [SCSI] hpsa: factor out hpsa_find_cfg_addrs.
Rationale for this is that I will also need to use this code
in fixing kdump host reset code prior to having the hba structure.

12d2cd4711 [SCSI] hpsa: make hpsa_find_memory_BAR not require the per HBA structure.
Rationale for this is that in order to fix the hard reset code used
by kdump, we need to use this function before we even have the per
HBA structure.

def342bd74 [SCSI] hpsa: fix block fetch table problem.
We have 32 (MAXSGENTRIES) scatter gather elements embedded
in the command.  With all these, the total command size is
about 576 bytes.  However, the last entry in the block fetch table
is 35.  (the block fetch table contains the number of 16-byte chunks
the firmware needs to fetch for a given number of scatter gather
elements.)  35 * 16 = 560 bytes, which isn't enough.  It needs to be
36. (36 * 16 == 576) or, MAXSGENTRIES + 4.  (plus 4 because there's a
bunch of stuff at the front of the command before the first scatter
gather element that takes up 4 * 16 bytes.)  Without this fix, the
controller may have to perform two DMA operations to fetch the
command since the first one may not get the whole thing.

33a2ffce51 [SCSI] hpsa: Increase the number of scatter gather elements supported.
This uses the scatter-gather chaining feature of Smart Array
controllers.  32 scatter-gather elements are embedded in the
"command list", and the last element in the list may be marked
as a "chain pointer", and point to an additional block of
scatter gather elements.  The precise number of scatter gather
elements supported is dependent on the particular kind of
Smart Array, and is determined at runtime by querying the
hardware.

31468401cc [SCSI] hpsa: remove scan thread
The intent of the scan thread was to allow a UNIT ATTENTION/LUN
DATA CHANGED condition encountered in the interrupt handler
to trigger a rescan of devices, which can't be done in interrupt
context.  However, we weren't able to get this to work, due to
multiple such UNIT ATTENTION conditions arriving during the rescan,
during updating of the SCSI mid layer, etc.  There's no way to tell
the devices, "stand still while I scan you!"  Since it doesn't work,
there's no point in having the thread, as the rescan triggered via
ioctl or sysfs can be done without such a thread.

2a8ccf3187 [SCSI] hpsa: fix bug in adjust_hpsa_scsi_table
fix bug in adjust_hpsa_scsi_table which caused devices which have
changed size, etc. to do the wrong thing.

The problem was as follows:

The driver maintains its current idea of what devices are present
in the h->dev[] array.  When it updates this array, it scans the
hardware, and produces a new list of devices, call it sd[], for
scsi devices.

Then, it compares each item in h->dev[] vs. sd[], and any items which
are not present sd it removes from h->dev[], and any items present
in sd[], but different, it modifies in h->dev[].

Then, it looks for items in sd[] which are not present in h->dev[],
and adds those items into h->dev[].  All the while, it keeps track
of what items were added and removed to/from h->dev[].

Finally, it updates the SCSI mid-layer by removing and adding
the same devices it removed and added to/from h->dev[]. (modified
devices count as a remove then add.)

originally, when a "changed" device was discovered, it was
removed then added to h->dev[].  The item was added to the *end*
of h->dev[].  And, the item was removed from sd[] as well
(nulled out).  As it processed h->dev[], these newly added items
at the end of the list were encountered, and sd[] was searched,
but those items were nulled out.  So they ended up getting removed
immediately after they were added.

The solution is to have a way to replace items in the h->dev[]
array instead of doing a remove + add.  Then the "changed" items.
are not encountered a second time, and removed.
