Currently there is no indication if R/W test fails during POST. This can
happen e.g. when user plugs in a card with unsupported type of memory.
Since the driver will be unusable, it's better to fail the whole POST
if the memory cannot be configured properly.

This patch reduces the number of sequential pointer derefs in
drivers/scsi/scsi_error.c

This has been submitted a number of times over a couple of years.  I
believe this version adresses all comments it has gathered over time.
Please apply or reject with a reason.

The benefits are:

 - makes the code easier to read.  Lots of sequential derefs of the same
   pointers is not easy on the eye.

 - theoretically at least, just dereferencing the pointers once can
   allow the compiler to generally slightly faster code, so in theory
   this could also be a micro speed optimization.

 - reduces size of object file (tiny effect: on x86-64, in at least one
   configuration, the text size decreased from 9439 bytes to 9400)

 - removes some pointless (mostly trailing) whitespace.

Remove incorrect Matrox G200eV support that was previously added by
commit e3a19388

A serious issue with the incorrect G200eV support that reproduces on the
Matrox G200eV equipped IBM x3650 M2 is the total lack of text (login
banner, login prompt, etc) on the console when X is not running and
total lack of text on all of the virtual consoles after X is started.

Any concerns that the incorrect code (upstream since October 2008) has
been successfully used on non-IBM G200eV equipped system(s) appear to be
unwarranted.  In addition to the serious/non-intermittent nature of
issues that have been spotted on IBM systems, complete removal of the
incorrect code is clearly supported by the following Matrox (Yannick
Heneault) provided input:
 "It impossible that this patch should have work on a system.
 The patch only declare the G200eV as a regular G200 which is
 not case. Many registers are different, including at least the
 PLL programming sequence. If the G200eV is programmed like a
 regular G200, it will not display anything."

v1 - Initial patch that removed the incorrect code for _all_
     G200eV equipped systems.
v2 - Darrick Wong provided patch that blacklisted the incorrect
     code on G200eV equipped IBM systems leaving it enabled on
     all G200eV equipped non-IBM systems.
v3 - Same code changes included with v1 plus additional
     justification for complete removal of the incorrect code.

Make the LM75/LM75A device detection faster:

* Don't read the current temperature value when we don't use it.
* Check for unused bits in the configuration register as soon as we
  have read its value.
* Don't use word reads, not all devices support this, and some which
  don't misbehave when you try.
* Check for cycling register values every 40 register addresses
  instead of every 8, it's 5 times faster and just as efficient.

Some of these improvements come straight from the user-space
sensors-detect script, so both detection routines are in line now.
