Currently the driver assumes that CPU 0 is handling all the hard IRQs.
This is wrong in Linux SMP systems where user is allowed to assign to
hardware IRQs to any CPU. The driver will stop working if user sets
smp_affinity so that interrupts end up being handled by other than CPU
0. The patch fixes that.

Pull SCSI target fixes from Nicholas Bellinger:
 "Here are the outstanding target fixes queued up for v3.12-rc4 code.

  The highlights include:

   - Make vhost/scsi tag percpu_ida_alloc() use GFP_ATOMIC
   - Allow sess_cmd_map allocation failure fallback to use vzalloc
   - Fix COMPARE_AND_WRITE se_cmd->data_length bug with FILEIO backends
   - Fixes for COMPARE_AND_WRITE callback recursive failure OOPs + non
     zero scsi_status bug
   - Make iscsi-target do acknowledgement tag release from RX context
   - Setup iscsi-target with extra (cmdsn_depth / 2) percpu_ida tags

  Also included is a iscsi-target patch CC'ed for v3.10+ that avoids
  legacy wait_for_task=true release during fast-past StatSN
  acknowledgement, and two other SRP target related patches that address
  long-standing issues that are CC'ed for v3.3+.

  Extra thanks to Thomas Glanzmann for his testing feedback with
  COMPARE_AND_WRITE + EXTENDED_COPY VAAI logic"

* git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
  iscsi-target; Allow an extra tag_num / 2 number of percpu_ida tags

Jonathan writes:

Third set of new functionality and cleanups for IIO in the 3.13 cycle.

Driver New Functionality
* MXS - new interrupt driven touch screen support for i.MX23/28. Old
  polled implementation dropped.

Driver Cleanups
* Some spi_sync boilerplate dropped by using spi_sync_transfer
* Some switching of drivers to the fractional type for scale reading.
  Moves the ugly calculation into one place.
* Fix the documentation for *_voltage_scale which is never been correct
  or as implemented in any driver.
* HID sensor hub and children : Open the sensor hub only when someone cares.
* hmc5843 - various minor
