c06fb90d75 Process AEN requests. We queue them to a work function. This works, however, 
there seems to be a problem with the Linux SCSI stack because when we delete a
LUN on the target, it does not get deleted from Linux. Still investigating.

b0a7281646 Remove a bunch of unneeded printk lines. Also, this line: 
TRACE_DBG("Created tid '%08lX'", (unsigned long)&tr_id[4]);

is wrong. All it will do is print the address of the fifth byte in the tr_id.

It should cast to an unsigned long * and deref it, at least. However, I have
anothe change that prints out the tr_id as a SAS address.

use an OUI that I think is not currently in use, so it seems unlikely that we
will clash with anyone else, but you never know. I might have to change it
later.

5737910fb4 Put in a clearer work-around for the problem with the size of the max_cmd_size 
field. The size changed at 2.6.26 from unsigned char to unsigned short.

8668b22ae8 Set max_cmd_len correctly depending on the size of the field. In earlier 
versions of Linux it was an unsigned char, and a value of 260 means 4 after a compiler warning. Added a comment to describe what is going on as well. Since 
this is done very infequently it should not cause performance problems and 
means that it will not silently fail to work if people try to use it on kernels
earlier than 2.6.26. If I figure out what kernel version the change was made
in we could use an ifdef.

23accb2e12 When converting the SCST source code into a series of upstream patches, SCST 
is built via the kbuild infastructure. In kernel version 2.6.24 (commit
f77bf01425b11947eeb3b5b54685212c302741b8) the kbuild variable ccflags-y has
been introduced and the use of EXTRA_CFLAGS in kbuild makefiles has been
deprecated. The patch below converts SCST's in-tree makefiles such that these
use ccflags-y instead of EXTRA_CFLAGS when generating kernel patches for
kernel 2.6.24 or later.

Additionally, this patch removes the "default n" from the file
scst/kernel/in-tree/Kconfig.scst since this statement is superfluous.

The patch below has been tested by verifying the output of the following
command:
for ((v=23;v<=32;v++)); do rm -rf re* && scripts/run-regression-tests 2.6.$v; done
