ib_srpt: Revert r7050
r7050 did not change any behavior so revert it. Note for myself: in the
ib_srpt driver the port number is set by the ib_modify_qp() call in
srpt_init_ch_qp().

scst: avoid false lockdep complaints about recursive locking
In some cases SCST needs to take multiple locks recursivly, e.g. to lock
all tgt_devs in a session. For this case SCST takes those locks in their
current sort order, e.g. by LUN for tgt_devs, then releases in the
opposite order. Unfortunately, lockdep complains on such actions as
recursive locking, then disables itself. The disabling itself action is
the most unpleasant one leading to lockdep being useless after this point.
Unfortunately, nested locking annotations can't help, because after
free, then alloc again, or after LUN change (in case of tgt_devs) order
of locks can change.
So, this patch implements a way to annotate some lock and unlock actions
as "no lockdep", so lockdep will not track them. It contains related
kernel patches for some kernels.
This is a debug aid only useful only with lockdep enabled kernels.

iscsi-scst: add target_ip attribute
It adds target_ip attribute containing target IP address in each
/sys/kernel/scst_tgt/targets/iscsi/TARGET/sessions/INITIATOR/INITIATOR_IP subdirectory.
It's useful to simplify monitoring management utilities

iscsi-scst: add per_sess_dedicated_tgt_threads attribute in ini groups
If this attrubute is set, each iSCSI session for this initiator has
dedicated, i.e. not shared with other sessions, pool of the iscsi{wr,rd}
kernel threads.
Useful to control per-session CPU affinity to improve performance.

This per-device attribute allows to control maximum number of SCSI
commands any session to this device can have in flight. It makes
currently hardcoded constant be run time configurable.

scst: add thread_index sysfs attribute
This attribute exports per LUN thread index assigned by
scst_add_threads(). It can be used to look up which export thread is
serving which target since this index also appears in the export thread
name. This information then could be used to set CPU affinity for those threads to improve performance.
