9ea7b8b4c9 We try to build FC SAN on Sun T2 server, FC HBA cards used are 
QLE2560 and QLE2562, the OS is RHEL6.0 with kernel linux-2.6.32,
scst code version from svn is 3952.

As T2 (SPARC64) is big-endian, which may not be tested sufficently,
we had to fix some endian swap to make qla2x00t work good on it.

The first fix is in q24_build_ctio_pkt(), loop_id from prm->cmd, which
was generated by CPU, should be converted to little-endian when wrapped
in pkt, which will be used by HBA ASIC.

The second fix in qla2x_tgt_def.h, reorder the bit-order of structs'
member, is an attempt in despair, cannot explain why, but it just works!

Besides the programming skills, we cannot get QLogic FC HBA databook,
and have little acknowledge about the driver, the fixes may need to
be refined, so don't hold the comments :)

63a6094cad Eliminate the blockio / fileio / nullio if-statements in 
vdisk_do_job() and the READ/WRITE functions called from that
function. Convert the opcode switch in vdisk_*do_job() to an
array with function pointers.

The function vdisk_exec_verify() only works for file I/O, so
rename it into fileio_exec_verify().

the format of byte 13 is defined as follows:
- The most significant four bits are SCOPE field.
- The least significant four bits are the TYPE field.
Make sure that that byte is filled in according to the specification.

59019ae405 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().

a2dcbab715 Fixes problem reported by Lev Vainblat <lev@zadarastorage.com>: 
The access to the session sysfs during logout may lead to the kernel oops. In iscsi_unreg_sess_done() the iscsi_session is freed, so scst_sess->tgt_priv (that previously pointed to the iscsi_session) becomes stale. The session is still accessible in sysfs until scst_sess_sysfs_del() call, but accessing to the session via sysfs may return invalid values or crash the kernel:

b579b06531 Instead of repeating the same name lookup several times, use vdev_find() 
where appropriate.

b3b4702bcb 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 &amp;.
- 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.
