When reading synchronously from a non-zero endpoint, gadgetfs will
return -EFAULT even if the read succeeds, due to a bad check of the
copy_to_iter() return value.

This fix compares the return value of copy_to_iter to the amount of
bytes that was passed, and only fails if they are not the same.

For case 14 and case 21, their correct return value is the number
of bytes transferred, so it is a positive integer. But in usbtest_ioctl,
it takes non-zero as false return value for usbtest_do_ioctl, so
it will treat the correct test as wrong test, then the time on
tests will be the minus value.

This patch fixes an issue that isochronous transfer's data is possible to

This patch fixes an issue that unexpected BRDY interruption happens
when the usb_ep_{enable,disable}() are called with different direction.
In this case, the driver will cause the following message:

 renesas_usbhs e6590000.usb: irq_ready run_error 1 : -16

This issue causes the followings:
 1) A pipe is enabled as transmission
 2) The pipe sent a data
 3) The pipe is disabled and re-enabled as reception.
 4) The pipe got a queue

Since the driver doesn't clear the BRDYSTS flags after 2) above, the issue
happens. If we add such clearing the flags into the driver, the code will
become complicate. So, this patch clears the BRDYSTS flag of reception in
usbhsg_ep_enable() to avoid complicate.

DWC3 has one interesting peculiarity with chained

get a short packet before processing all N TRBs,
DWC3 will (conditionally) issue a XferComplete or
XferInProgress event and retire all TRBs from the
one which got a short packet to the last without
clearing their HWO bits.

This means SW must clear HWO bit manually, which

rename the member, to force old and out-of-tree code to break
at compile time instead of at runtime.

care about whether it's a read or a write at that level, just
pass in a bool 'is_write' parameter instead.

Pull more xfs updates from Dave Chinner:
 "This is the second part of the XFS updates for this merge cycle, and
  contains the new reverse block mapping feature for XFS.

  Reverse mapping allows us to track the owner of a specific block on
  disk precisely.  It is implemented as a set of btrees (one per
  allocation group) that track the owners of allocated extents.
  Effectively it is a "used space tree" that is updated when we allocate
  or free extents.  i.e. it is coherent with the free space btrees we
  already maintain and never overlaps with them.

  This reverse mapping infrastructure is the building block of several
  upcoming features - reflink, copy-on-write data, dedupe, online
  metadata and data scrubbing, highly accurate bad sector/data loss
  reporting to users, and significantly improved reconstruction of
  damaged and corrupted filesystems.  There's a lot of new stuff coming
  along in the next couple of cycles,a nd it all builds in the rmap
  infrastructure.

  As such, it's a huge chunk of new code with new on-disk format
  features and internal infrastructure.  It warns at mount time as an
  experimental feature and that it may eat data (as we do with all new
  on-disk features until they stabilise).  We have not released
  userspace suport for it yet - userspace support currently requires
  download from Darrick's xfsprogs repo and build from source, so the
  access to this feature is really developer/tester only at this point.
  Initial userspace support will be released at the same time kernel
  with this code in it is released.

  The new rmap enabled code regresses 3 xfstests - all are ENOSPC
  related corner cases, one of which Darrick posted a fix for a few
  hours ago.  The other two are fixed by infrastructure that is part of
  the upcoming reflink patchset.  This new ENOSPC infrastructure
  requires a on-disk format tweak required to keep mount times in
  check - we need to keep an on-disk count of allocated rmapbt blocks so
  we don't have to scan the entire btrees at mount time to count them.

  This is currently being tested and will be part of the fixes sent in
  the next week or two so users will not be exposed to this change"

Pull arch/sh updates from Rich Felker:
 "These changes improve device tree support (including builtin DTB), add
  support for the J-Core J2 processor, an open source synthesizable
  reimplementation of the SH-2 ISA, resolve a longstanding sigcontext
  ABI mismatch issue, and fix various bugs including nommu-specific
  issues and minor regressions introduced in 4.6.

  The J-Core arch support is included here but to be usable it needs
  drivers that are waiting on approval/inclusion from their subsystem
  maintainers"
