Commit cae2a173

 ("x86: clean up/fix 'copy_in_user()' tail zeroing")
fixed the failure case tail zeroing of one special case of the x86-64
generic user-copy routine, namely when used for the user-to-user case
("copy_in_user()").

But in the process it broke an even more unusual case: using the user
copy routine for kernel-to-kernel copying.

Now, normally kernel-kernel copies are obviously done using memcpy(),
but we have a couple of special cases when we use the user-copy
functions.  One is when we pass a kernel buffer to a regular user-buffer
routine, using set_fs(KERNEL_DS).  That's a "normal" case, and continued
to work fine, because it never takes any faults (with the possible
exception of a silent and successful vmalloc fault).

But Jan Beulich pointed out another, very unusual, special case: when we
use the user-copy routines not because it's a path that expects a user
pointer, but for a couple of ftrace/kgdb cases that want to do a kernel
copy, but do so using "unsafe" buffers, and use the user-copy routine to
gracefully handle faults.  IOW, for probe_kernel_write().

And that broke for the case of a faulting kernel destination, because we
saw the kernel destination and wanted to try to clear the tail of the
buffer.  Which doesn't work, since that's what faults.

This only triggers for things like kgdb and ftrace users (eg trying
setting a breakpoint on read-only memory), but it's definitely a bug.
The fix is to not compare against the kernel address start (TASK_SIZE),
but instead use the same limits "access_ok()" uses.

Pull MTD updates from Brian Norris:
 "Common MTD:

   - Add Kconfig option for keeping both the 'master' and 'partition'
     MTDs registered as devices.  This would really make a better
     default if we could do it over, as it allows a lot more flexibility
     in (1) determining the flash topology of the system from user-space
     and (2) adding temporary partitions at runtime (ioctl(BLKPG)).

     Unfortunately, this would possibly cause user-space breakage, as it
     will cause renumbering of the /dev/mtdX devices.  We'll see if we
     can change this in the future, as there have already been a few
     people looking for this feature, and I know others have just been
     working around our current limitations instead of fixing them this
     way.

   - Along with the previous change, add some additional information to
     sysfs, so user-space can read the offset of each partition within
     its master device

  SPI NOR:

   - add new device tree compatible binding to represent the
     mostly-compatible class of SPI NOR flash which can be detected by

Pull ARM SoC late changes from Olof Johansson:
 "We were expecting to sit on this branch through most of the merge
  window since the contents was merged into our tree late, but we ended
  up sitting on all of our contents so it can go in with the rest.

  The contents here is:

   - a large branch of cleanups of the CM/PRM blocks on OMAP.

   - a couple of patches plumbing up CM/PRM on OMAP5 and DRA7.

   - a branch with DT updates for Freescale i.MX.  including some
     shuffling from .dts to .dtsi (include) files that causes a little
     churn"
