  scst: Switch from the cpu_*() to the cpumask_*() API
  
  The cpus_*() functions were deprecated via patch "cpumask:
  introduce new API, without changing anything" (November 2008,
  commit ID 2d3854a37e8b). Hence switch from the cpus_*() API to
  the cpumask_*() API.
  
  This patch has the intended side effect of not adding the "[key]"
  property to cpumask sysfs attributes that contain the default
  cpumask. The current code namely reads uninitialized bits on
  systems where nr_cpu_ids < NR_CPUS because cpus_equal() compares
  more bits than those that were set by cpumask_copy().

  scst_vdisk: Make vdisk_nullio size configurable
  
  Keep the default size of vdisk_nullio devices at VDISK_NULLIO_SIZE. Add
  a sysfs attribute 'size' which is the size of a vdisk device in
  bytes. Make the size of vdisk_nullio devices configurable. Accept
  "size" and "size_mb" as creation parameters for vdisk_nullio
  devices. Generate a CAPACITY DATA HAS CHANGED unit attention after size
  changes. Refuse any attempt to change the size into a number that is
  not a multiple of the block size.

  Hush Coverity warning of scst_ws_push_single_write() uninitialized pointer
  
  Coverity warns that sgv may be used uninitialized. The warning
  applies to WRITE SAME commands with LBDATA == PBDATA == 0 (replicate
  a single block of user data into the specified LBA range).
  
  The warning appears to be spurious - when LBDATA == PBDATA == 0,
  scst_ws_write_cmd_finished() will not use the uninitialized value
  saved by scst_ws_push_single_write().
  
  Move initialization of sgv earlier in the function to quiesce the warning.

  scst_user, rt: Wake command processing thread when needed
  
  In a fully-preemptible realtime kernel (CONFIG_PREEMPT_RT_FULL=y),
  SCSI commands from an initiator time out because the userland target
  application is never woken to process them.
  
  This is because in a fully-preemptible realtime kernel, soft-IRQ
  (tasklet) execution always occurs in a ksoftirqd thread and
  preempt_count is not manipulated on soft-IRQ processing entry/exit.
  This makes in_interrupt() useless for determining whether soft-IRQ
  processing is occurring; instead, in_serving_softirq() should be
  used for that purpose.

  Fix spurious BUG when parse_type != SCST_USER_PARSE_STANDARD
  
  Changeset 4224 introduced EXTRACHECKS for valid lba/data_len and state
  at the end of the parsing phase of command processing.
  However, the checks do not account for deferral of parsing to userland,
  as occurs when SCST_USER_PARSE_CALL or SCST_USER_PARSE_EXCEPTION are specified.
  In such cases the checks report errors on commands that userland has not yet
  had an opportunity to parse.
  
  NOTE: this includes a refactoring of the EXTRACHECKS to improve clarity.
        The rework is not exactly equivalent to the original code, but does
        conform to the comments describing the original code.
        Specifically, the original code would not trap an illegal command state
        unless there was also an illegal lba or data_len.

  Makefiles: calculate KVER properly
      
  When deriving the kernel version (KVER) from KDIR, the file
  $(KDIR)/include/config/kernel.release should be preferred over
  'make kernelversion'.
  
  For example, the Ubuntu 3.2.0-23-generic kernel has a kernel.release
  file containing '3.2.0-23-generic', but 'make kernelversion' returns
  3.2.14. Since the modules are stored under /lib/modules/3.2.0-23-generic,
  the value in kernel.release is the correct one to use.
      
  Also:
  - Evaluate KVER only once
  - All depmod commands must include KVER

  scst, qla2x00t: Prevent inappropriate sleeping with a real-time kernel
  
  With a realtime kernel with full preemption (CONFIG_PREEMPT_RT_FULL),
  spinlocks can sleep, interrupt handlers run in thread context, and
  the standard local_irq functions manipulate preemptibility, not HW
  interruptibility. Under these conditions, most calls to local_irq
  functions should be replaced by no-ops. The CONFIG_PREEMPT_RT patch
  defines _nort versions of local_irq functions that compile away
  under CONFIG_PREEMPT_RT_FULL and compile to their "normal"
  equivalents otherwise.
  
  Define _nort equivalents to support compilation against both
  "normal" and RT-patched kernels, and use the _nort local_irq
  functons in cases where spinlocks are taken within a
  local_irq_save() or local_irq_disable() block.  Without these
  changes, runtime warnings about "sleeping function called from
  invalid context" occur.
