From Bart Van Assche <bvanassche@acm.org>:
As Mikko Kortelainen <kordex@gmail.com> explained on the SCST IRC
channel, it's not necessary to replace the qla2xxx directory in the
kernel source tree in order to build the SCST qla2x00t target driver.
Also, if neither SCSI pass-through nor iSCSI will be used rebuilding
the kernel tree can be skipped entirely. The patch below updates the
qla2x00t howto accordingly, and also implements the following changes:
- Fix everything the W3C HTML validator complains about:
- Add DOCTYPE declaration.
- Add charset declaration.
- Change </br> into <br> since </br> is invalid.
- Change one occurrence of & into &.
- Use proper HTML constructs for numbered and unnumbered enumerations.
- Use a fixed-sized font and the brown color for all computer output
text (via inline CSS).
- Use hyperlinks to refer to other steps.
- Fix spelling errors.
- Merge the Debian and non-Debian howto's because the differences are
so small that it's not justified to maintain two different documents.

Use get/put_unaligned() instead of open coding these such that the
compiler can generate better code.
As an example, the get_unaligned_be24() function used in the
implementation of READ_6, WRITE_6 and VERIFY_6 together with
"& 0x1f0000" is inlined by the compiler and is translated as
follows on an x86_64 system (2031616 equals 0x1f0000):
movl 0(%r13), %r11d
bswapl %r11d
andl $2031616, %r11d
Also eliminate a conditional branch instruction from get_trans_len_1_256().

Patch from Abhilash Sankar <Abhilash.S@hcl.com> with some fixes
Issue:
------------
The DevRegAttribute is sending a different Source Attribute (ISCSI name) which
represents the Storage Node for each target. So Microsoft isns server considers
the last request as the storage node and doesn't discover the previous targets.
Root Cause
----------------
Function ISNS_FUNC_DEV_ATTR_REG
Target A
Source attribute
ISCSI-Name = <IQN A Name>
Operating Attribute
ISCSI-Name = <IQN A Name>
Flags
Replace Access = 1
Target B
Source attribute
ISCSI-Name = <IQN B Name>
Operating Attribute
ISCSI-Name = <IQN B Name>
Replace Access = 1
So as per the request format Microsoft isns Server always takes the last target
as the source node. and register the same. Hence it doesn't discover the
targets other than last one. The Source Attribute has to be fixed for all targets. It
would be better if we use the first target iscsi name (rather than the last target
iscsi name) as source attribute iscsi name to represent the storage node.

Fix two race conditions that could trigger this failure:
- Completion thread not woken up after channel state change.
- Reception of Last WQE event before the channel queue pair was reset.

Modified patch from Bart Van Assche <bvanassche@acm.org>:
The range unmapped by the scst_vdisk handler when processing an UNMAP command
is not correct. The patch below fixes that and also prevents that the following
kernel crash can be triggered on the target:

Invoking truncate_range() with an end len that is not page-size aligned
triggers it. In other words, with a block size that is below
PAGE_CACHE_SIZE some UNMAP commands could trigger a kernel bug. I think
it's better to print an error message and to skip an UNMAP command
instead of triggering a kernel oops.

The implementation of many tracing macros in scst_debug.h (like TRACE_DBG)
requires that at least one more argument must be provided in addition to format
which in some cases is an overkill. This patch fixes the issue and also unifies
macro signatures for the cases when CONFIG_SCST_DEBUG is either on or off.

Major cleanups:
