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"

of ohci controller. Alan Stern suggested, properly handle
ohci-da8xx suspend scenario.

Calling explicitly the ohci_suspend()
routine in ohci_da8xx_suspend() will ensure proper
handling of suspend scenario.

Suspend scenario in case of OHCI was not properly
handled in ochi_suspend()routine. Alan Stern
suggested, properly handle OHCI suspend scenario.

This does generic proper handling of suspend
scenario to all OHCI SOC.

If USB_FUNCTIONFS is selected without USB_FUNCTIONFS_ETH and
USB_FUNCTIONFS_RNIS, u_ether.h won't be included and then
USB_ETHERNET_MODULE_PARAMAETERS macro won't be available causing the
following warning compilation:

drivers/usb/gadget/g_ffs.c:81:1: warning: data definition has no type or
storage class [enabled by default]
drivers/usb/gadget/g_ffs.c:81:1: warning: type defaults to ‘int’ in
declaration of ‘USB_ETHERNET_MODULE_PARAMETERS’ [-Wimplicit-int]
drivers/usb/gadget/g_ffs.c:81:1: warning: function declaration isn’t a
prototype [-Wstrict-prototypes]

This patch fixes the warning by making USB_ETHERNET_MODULE_PARAMETERS to
be used iff u_ether.h is included, otherwise it is not needed.

This patch adds support for isochronous out transfers to the HWA.  The
primary changes are:

1.  Add a isoc_pack_desc_urb field to struct wa_seg.  This urb is used
to send the isochronous packet info message to the HWA which describes
the isoc data segment(s) that will be sent as the payload of the
transfer request.

2.  Use the URB iso_frame_desc field to populate the isochronous packet
info message and data segments sent to the HWA.

3.  After the data is sent and transfer result is returned from the
HWA, read the isoc packet status message from the HWA.  The contents of
the isoc packet status message are used to set the iso_frame_desc
status and actual_length fields in the original isoc URB.  This feature
required the addition of a some state tracking variables in struct wahc
so the dti_urb knows what type of packet it expects to receive next.
