This patch does two things for SCM eUSCSI USB-SCSI converters:

1. SCM eUSCSI bridge devices are hard-wired to use SCSI ID 7. On connecting
the converter, access to that ID is attempted during the bus scan. Asking
the converter to issue INQUIRY commands to itself isn't very polite and
wastes time. Set this_id to 7 so __scsi_scan_target() skips it in the scan.

2. Enable multi-LUN support. eUSCSI devices don't support Get Max LUN
requests, returning an error (-32). [Different targets could have different
numbers of LUNs, so it wouldn't make sense to return a particular value in
response to Get Max LUN.]

usb_stor_scan_dwork() does this:
    /* For bulk-only devices, determine the max LUN value */
    if (us->protocol == USB_PR_BULK && !(us->fflags & US_FL_SINGLE_LUN)) {
            mutex_lock(&us->dev_mutex);
            us->max_lun = usb_stor_Bulk_max_lun(us);
            mutex_unlock(&us->dev_mutex);

It avoids calling usb_stor_Bulk_max_lun() if US_FL_SINGLE_LUN, but not for
US_FL_SCM_MULT_TARG. Since usb_stor_Bulk_max_lun() returns 0 in the error
case, us->max_lun was always set to 0.

[If the user doesn't want multi-LUN support (perhaps there are SCSI devices
which respond to commands on all LUNs?), the US_FL_SINGLE_LUN quirk can be
specified on the kernel command line.]

usb_stor_euscsi_init() enables multi-target mode for SCM eUSB SCSI bridge
devices. The control message it sends has wLength = 1 and the byte sent is
0x01. While that works, the SCM Windows driver does it with wLength = 0. We
may as well match what the SCM driver does.

Pull xfs fixes from Dave Chinner:
 "This update fixes a warning in the new pagecache_isize_extended() and
  updates some related comments, another fix for zero-range
  misbehaviour, and an unforntuately large set of fixes for regressions
  in the bulkstat code.

  The bulkstat fixes are large but necessary.  I wouldn't normally push
  such a rework for a -rcX update, but right now xfsdump can silently
  create incomplete dumps on 3.17 and it's possible that even xfsrestore
  won't notice that the dumps were incomplete.  Hence we need to get
  this update into 3.17-stable kernels ASAP.

  In more detail, the refactoring work I committed in 3.17 has exposed a
  major hole in our QA coverage.  With both xfsdump (the major user of
  bulkstat) and xfsrestore silently ignoring missing files in the
  dump/restore process, incomplete dumps were going unnoticed if they
  were being triggered.  Many of the dump/restore filesets were so small
  that they didn't evenhave a chance of triggering the loop iteration
  bugs we introduced in 3.17, so we didn't exercise the code
  sufficiently, either.

  We have already taken steps to improve QA coverage in xfstests to
  avoid this happening again, and I've done a lot of manual verification
  of dump/restore on very large data sets (tens of millions of inodes)
  of the past week to verify this patch set results in bulkstat behaving
  the same way as it does on 3.16.

  Unfortunately, the fixes are not exactly simple - in tracking down the
  problem historic API warts were discovered (e.g xfsdump has been
  working around a 20 year old bug in the bulkstat API for the past 10
  years) and so that complicated the process of diagnosing and fixing
  the problems.  i.e. we had to fix bugs in the code as well as
  discover and re-introduce the userspace visible API bugs that we
  unwittingly "fixed" in 3.17 that xfsdump relied on to work correctly.

  Summary:

   - incorrect warnings about i_mutex locking in pagecache_isize_extended()
     and updates comments to match expected locking
   - another zero-range bug fix for stray file size updates
   - a bunch of fixes for regression in the bulkstat code introduced in
     3.17"

It's desirable for allnconfig and tinyconfig targets to result in the

switch off DEV_COREDUMP regardless if any drivers select
WANT_DEV_COREDUMP.

This patch renames the option to ENABLE_DEV_COREDUMP and setting it to
'n' (as in allnconfig or tinyconfig) will effectively disable device
coredump.

If CONFIG_XEN_DOM0 is enabled, the ehci-dbgp driver notifies Xen of
controller reset events via xen_dbgp_reset_prep() and
xen_dbgp_external_startup() (via calls to xen_dbgp_op().)  Otherwise
<linux/usb/ehci_def.h> defines them as no-ops to disable this logic.

The fotg210 driver copies much of the dbgp code from ehci_def.h, but it
unconditionally defines the Xen hooks as no-ops, effectively disabling
these notifications when CONFIG_EARLY_PRINTK_DBGP is disabled.  When
enabled, though, notifying Xen is dependent on CONFIG_XEN_DOM0 due to
fotg210 leveraging the ehci-dbgp driver.

The following table compares the implementations of xen_dbgp_reset_prep()

This suggests that fotg210 is, at best, indifferent to whether Xen is
