08e532715d Remove procfs support 
Since all RHEL/CentOS 5 users have upgraded to a newer version, procfs
support is no longer necessary. Hence remove procfs support. This patch
has been generated as follows:

git grep -lw CONFIG_SCST_PROC iscsi-scst qla2x00t scst scst_local srpt |\
  while read f; do
    echo ${f}
    unifdef -U CONFIG_SCST_PROC ${f} >${f}.out
    mv ${f}.out ${f}
  done

followed by two small manual edits in scst/include/scst.h and also in
qla2x00t/qla2x00-target/qla2x00t.c.

This patch modifies scst_local such that on kernel version 3.19 and
later multiple hardware queues are used (scsi-mq). Note: in order
to benefit from concurrent processing, the number of SCST command
threads must be set to a value above one.

4ac6d7a26d [PATCH] scst: Drop detect() method 
There is no need for a detect() method - code that is present in such
a method can be moved to module_init(). Hence declare this method
obsolete. Leave the detect pointer member in the target template for
now for out-of-tree SCST drivers.
