According to SPC-4 in the PERSISTENT RESERVE IN full status descriptor
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.

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 :)

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.

scst: Avoid triggering BUG() on uniprocessor systems
On uniprocessor systems with lock debugging disabled spin_is_locked()
returns false. Disable the spin_is_locked() checks if CONFIG_SMP has not
