Pull drm fixes from Dave Airlie:
"Some final few intel fixes, all regressions, all stable cc, and one
exynos oops fixer.
The biggest is probably the intel display error irqs one, but it seems
to fix a few crashes on startup, and one use after free in drm core"
* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
drm/exynos: Fix (more) freeing issues in exynos_drm_drv.c

Revert "drm/i915: don't touch the VDD when disabling the panel"
drm: Fix use-after-free in the shadow-attache exit code

Srikar Dronamraju reports that commit b0c29f79ecea ("futexes: Avoid
taking the hb->lock if there's nothing to wake up") causes java threads
getting stuck on futexes when runing specjbb on a power7 numa box.
The cause appears to be that the powerpc spinlocks aren't using the same
ticket lock model that we use on x86 (and other) architectures, which in
turn result in the "spin_is_locked()" test in hb_waiters_pending()
occasionally reporting an unlocked spinlock even when there are pending
waiters.
So this reinstates Davidlohr Bueso's original explicit waiter counting
code, which I had convinced Davidlohr to drop in favor of figuring out
the pending waiters by just using the existing state of the spinlock and
the wait queue.

Add remove_linear_migration_ptes_from_nonlinear(), to fix an interesting
little include/linux/swapops.h:131 BUG_ON(!PageLocked) found by trinity:
indicating that remove_migration_ptes() failed to find one of the
migration entries that was temporarily inserted.
The problem comes from remap_file_pages()'s switch from vma_interval_tree
(good for inserting the migration entry) to i_mmap_nonlinear list (no good
for locating it again); but can only be a problem if the remap_file_pages()
range does not cover the whole of the vma (zap_pte() clears the range).
remove_migration_ptes() needs a file_nonlinear method to go down the
i_mmap_nonlinear list, applying linear location to look for migration
entries in those vmas too, just in case there was this race.
The file_nonlinear method does need rmap_walk_control.arg to do this;
but it never needed vma passed in - vma comes from its own iteration.

The current devfreq_update_status() has the following bugs:
- If previous frequency doesn't have a valid level, it does an out of bounds
access into the trans_table and causes memory corruption.
- When the new frequency doesn't have a valid level, the time spent in the
new frequency is counted towards the next valid frequency switch instead of
being ignored.
- The time spent on the previous frequency is added to the new frequency's
stats instead of the previous frequency's stats.
This patch fixes all of this.

The following pattern is currently not well supported by RCU:
1. Make data element inaccessible to RCU readers.
2. Do work that probably lasts for more than one grace period.
3. Do something to make sure RCU readers in flight before #1 above
have completed.
Here are some things that could currently be done:
a. Do a synchronize_rcu() unconditionally at either #1 or #3 above.
This works, but imposes needless work and latency.
b. Post an RCU callback at #1 above that does a wakeup, then
wait for the wakeup at #3. This works well, but likely results
in an extra unneeded grace period. Open-coding this is also
a bit more semi-tricky code than would be good.
This commit therefore adds get_state_synchronize_rcu() and
cond_synchronize_rcu() APIs. Call get_state_synchronize_rcu() at #1
above and pass its return value to cond_synchronize_rcu() at #3 above.
This results in a call to synchronize_rcu() if no grace period has
elapsed between #1 and #3, but requires only a load, comparison, and
memory barrier if a full grace period did elapse.

Pentium M
Many Pentium M systems disable PAE but may have a functionally usable PAE
implementation. This adds the "forcepae" parameter which bypasses the boot
check for PAE, and sets the CPU as being PAE capable. Using this parameter
will taint the kernel with TAINT_CPU_OUT_OF_SPEC.

This replaces a decent amount of incomprehensible and buggy code
with much more straightforward code. It also brings the 32-bit vdso
more in line with the 64-bit vdsos, so maybe someday they can share
even more code.
This wastes a small amount of kernel .data and .text space, but it
avoids a couple of allocations on startup, so it should be more or
less a wash memory-wise.

sh_eth: Fix the race between open and MDIO bus registration
This patch series fixes the race condition that exists in the sh_eth driver
between network device open and MDIO bus registration. The actual fix is in
patch 4/5, with previous patches preparing the driver and patch 5/5 cleaning
up an unrelated issue.
I've based the idea on Sergei's attempt to fix the problem and can successfully
boot the Koelsch board over NFS with this series. I might have missed other
issues though, hence the RFC status.
The patches are based on top of the latest net-next master branch.

Memory allocated for the MDIO bus with the devm_kzalloc() API is
associated with the network device. While this will cause memory to be
freed at the right time, it doesn't allow allocating memory before the
network device is initialized.
Replace the network device with the parent platform device for memory
allocation to remove that dependency. This also improves consistency
with the other devm_* calls in the driver that all use the platform
device.

This makes the generic of_mdiobus_register parse the DT compatible string for
the pattern ethernet-phy-idAAAA.BBBB. If present it should be a value that
matches the phy-id register normally readable through MDIO.
When the ID is given the phy autoprobing is defeated and the phy is
created directly.
This is necessary to support phy's that cannot be autoprobed when
of_mdiobus_register is called. Specifically, my case has the phy in reset at
of_mdiobus_register, the reset is only released once the ethernet driver
starts, before it attaches to the phy.

mlx4: Add support for single port VFs
The mlx4 Firmware && driver expose both ports of the device through one PCI function.
This can be non-optimal under virtualization schemes where the admin
would like the VF to expose one interface to the VM, etc.
This series from Matan Barak adds support for single ported VFs.
Since all the VF interaction with the firmware passes through the PF
driver, we can emulate to the VF they have one port, and further create
a set of the VFs which act on port1 of the device and another set which
acts on port2.

Adds support for N-Port VFs, this includes:
1. Adding support in the wrapped FW command
In wrapped commands, we need to verify and convert
the slave's port into the real physical port.
Furthermore, when sending the response back to the slave,
a reverse conversion should be made.
2. Adjusting sqpn for QP1 para-virtualization
The slave assumes that sqpn is used for QP1 communication.
If the slave is assigned to a port != (first port), we need
to adjust the sqpn that will direct its QP1 packets into the
correct endpoint.
3. Adjusting gid[5] to modify the port for raw ethernet
In B0 steering, gid[5] contains the port. It needs
to be adjusted into the physical port.
4. Adjusting number of ports in the query / ports caps in the FW commands
When a slave queries the hardware, it needs to view only
the physical ports it's assigned to.
5. Adjusting the sched_qp according to the port number
The QP port is encoded in the sched_qp, thus in modify_qp we need
to encode the correct port in sched_qp.

with each check.
Jacob provides six fixes/cleanups for ixgbe, most notably, correct
the stop_mac_link_on d3() to check the Core Clock Disable bit before
stopping link and to fully check to see if manage firmware is running or
could be enabled before bringing down the link. Fix flow control
auto-negation for KR/KX/K4 interfaces, since setting up MAC link, the
cached autoc value and current autoc value were being incorrectly used to
determine whether link reset is required.
Emil provides a fix for ixgbe where there was a chance for aggressive
start_ndo_zmit() callers to sneak packets between enabling the Tx queues
and the link coming up. To resolve this, move the call to enable Tx
queues to after the link is established.

The documentation for how to use netlink mmap interface is incorrect.
The calls to setsockopt() require an additional argument.

Pull MIPS fixes from Ralf Baechle:
"Another set of five fixes. The most interesting one is a fix for race
condition in the local_irq_disable() implementation used by .S code
for pre-MIPS R2 processors only. It leaves a race that's hard but not
impossible to hit; the others fairly obvious"
