Pull rdma fixes from Doug Ledford:
"This is the second pull request for the rdma subsystem. Most of the
patches are small and obvious. I took two patches in that are larger
than I wanted this late in the cycle.
The first is the hfi1 patch that implements a work queue to test the
QSFP read state. I originally rejected the first patch for this
(which would have place up to 20 seconds worth of udelays in their
probe routine). They then rewrote it the way I wanted (use delayed
work tasks to wait asynchronously up to 20 seconds for the QSFP to
come alive), so I can't really complain about the size of getting what
I asked for :-/.
The second is large because it switches the rcu locking in the debugfs
code. Since a locking change like this is done all at once, the size
it what it is. It resolves a litany of debug messages from the
kernel, so I pulled it in for -rc.
The rest are all typical -rc worthy patches I think.
There will still be a third -rc pull request from the rdma subsystem
this release. I hope to have that one ready to go by the end of this
week or early next.

The hardened usercopy is now consistently avoiding checks against const
sizes, since we really only want to perform runtime bounds checking
on lengths that weren't known at build time. To test the hardened usercopy
code, we must force the length arguments to be seen as non-const.
Signed-off-by: Kees Cook <keescook@chromium.org>
Instead of having each caller of check_object_size() need to remember to
check for a const size parameter, move the check into check_object_size()
itself. This actually matches the original implementation in PaX, though
this commit cleans up the now-redundant builtin_const() calls in the
various architectures.
Signed-off-by: Kees Cook <keescook@chromium.org>
As already done with __copy_*_user(), mark copy_*_user() as __always_inline.
Without this, the checks for things like __builtin_const_p() won't work
consistently in either hardened usercopy nor the recent adjustments for
detecting usercopy overflows at compile time.

In case thermal_zone_xxx_register() returns an error, priv->zone
isn't NULL any more, but contains the error code.
This is passed to thermal_zone_device_unregister(), then. This checks

with the error code as a pointer. Crashing immediately.

Commit 833f2cbf70 ("ARM: dts: imx6: change the core clock of spdif")
changed many more clocks than only the SPDIF core clock as stated in
the commit message.
The MLB clock has been added and this causes SPDIF regression as
reported by Xavi Drudis Ferran and also in this forum post:
https://forum.digikey.com/thread/34240
The MX6Q Reference Manual does not mention that MLB is a clock related
to SPDIF, so change it back to a dummy clock to restore SPDIF
functionality.

Pull USB/PHY fixes from Greg KH:
"Here are some USB and PHY driver fixes for 4.8-rc5
Nothing major, lots of little fixes for reported bugs, and a build fix
for a missing .h file that the phy drivers needed. All of these have
been in linux-next for a while with no reported issues"

In commit 8ead9dd547 ("devpts: more pty driver interface cleanups") I
made devpts_get_priv() just return the dentry->fs_data directly. And
because I thought it wouldn't happen, I added a warning if you ever saw
a pts node that wasn't on devpts.
And no, that warning never triggered under any actual real use, but you
can trigger it by creating nonsensical pts nodes by hand.
So just revert the warning, and make devpts_get_priv() return NULL for
that case like it used to.

When reading SPI flash as MTD device, the transfer length is
directly passed to the spi driver. If the requested data size
exceeds 512KB, it will cause the time out calculation to
overflow since transfer length is 32-bit unsigned integer.
This issue is resolved by using 64-bit unsigned integer
to perform the arithmetic.
