369863f015 Allow install SCST in any location 
Currently the install location of SCST is pretty much hard coded into 
the Makefiles to be /usr/local.

I am custom building a system for ZFS & SCST and I want to install in 
/usr instead of /usr/local.

Currently I am doing a “find . -name Makefile -exec sed -i 's:/usr/local:/usr:g'
{} \;” to accommodate this.

This patch fixes it.

bd7c893f04 Multiple makefiles: autodetect SCST include directory 
It is cumbersome to change SCST_INC_DIR and SCST_DIR in each Makefile
before and after a release. Hence modify the Makefiles such that these
paths are detected automatically.

8ce28aaba2 Avoid that enabling a target too quickly triggers a crash 
The sysfs attributes of a target can be accessed before scst_tgt.tgt_priv
has been set. Avoid that such an access triggers a crash.

From: "Paul E. McKenney" <paul.mckenney@linaro.org>

The call_rcu() in ft_tport_delete() invokes ft_tport_rcu_free(),
which just does a kfree().  So convert the call_rcu() to kfree_rcu(),
allowing ft_tport_rcu_free() to be eliminated.

2125cb8400 fcst: Complain when refusing login 
Log an error message when refusing login because a target port has not yet been enabled
such that fcst users have a way to find out what happened.

Also, make sure that ft_prli() returns a value in the range of the enumeration type
fc_els_spp_resp. Note: since the return value of ft_prli() is only compared against
FC_SPP_RESP_ACK in the current libfc implementation, this change doesn't affect the
behavior of fcst.

had the wrong version of 22-lport-notify.   This corrects that.

649fef691e Changes to make fcst work on Linux 2.6.36. 
The biggest difference is that libfc no longer allocates a sequence
and exchange for incoming requests, and that eliminates a parameter
on the receive function.  This was done to help performance and
might help on short reads sometime in the future.

This also fixes an error in ft_send_read_data() that exceeds the
skb's SG list length limit on long reads when the NIC
supports large send offload.

I also made other minor changes like adding debugging.

ac5618b07e Adding patches for 2.6.36. These are similar to the 2.6.35 patches 
except for line number changes and a few interface changes imposed
by differences in libfc between 2.6.35 and 2.6.36, mostly due to the
change which doesn't allocate an exchange and sequence for incoming
requests.

ff7a986329 Add an fcoe patch for 2.6.35 to not deliver frames to fcst from softirq level. 
I believe this was causing a race leading to a WARN in fc_seq_send that
the sequence initiative wasn't held in ft_send_response().  It also caused
a problem for tcm_fc.

d8392af840 Apparently sparse ignores __attribute__((packed)) when applied to an enum 
while gcc honors this attribute. The result is that
sizeof(struct fcoe_rcv_info) is 48 when the header include/scsi/fc_frame.h is
compiled with gcc and that sizeof(struct fcoe_rcv_info) > 48 when the same
header is compiled by sparse. As a result, compilation with sparse fails due
to the BUILD_BUG_ON() statement in the function fcoe_dev_from_skb(), even
when checking a vanilla Linux kernel with sparse. The patch below slightly
modifies include/scsi/fc_frame.h such that gcc and sparse interpret this header
in the same way.

Note: it is fine to revert this patch once the behavior of gcc and sparse is
again in sync.
