 "This has our usual assortment of fixes and cleanups, but the biggest

  are any problems, but it has held up really well in testing so far.

  For very large filesystems (30T+) our existing free space caching code
  can end up taking a huge amount of time during commits.  The new tree
  based code is faster and less work overall to update as the commit
  progresses.

  Omar worked on this during the summer and we'll hammer on it in

This ensures that we always notify context tracking that we
have exited from user space no matter how we enter the kernel.
It is similar to how arm64 handles context tracking, for example.

were added in commit 49e4e156 ("tile: support CONTEXT_TRACKING and

This flag value is saved in ptregs and used to decide whether
to disable irqs when returning from the kernel.  Commit 1168df528fe4
("tile: don't assume user privilege is zero") performed a bad
merge from some KVM-enabled code that had not yet been upstreamed.

The only issue with the old code is that we will read the interrupt
mask in more conditions than we need to (e.g., coming from user
space when user space has the Interrupt Critical Section bit set, or
coming from a guest kernel), which is a slow multi-cycle operation.
This change saves those few cycles in the common case.

This change is a prerequisite change for TASK_ISOLATION but also
stands on its own for readability and maintainability.  The existing
tile do_work_pending() was called in a loop from assembly on
the slow path; this change moves the loop into C code as well.
For the x86 version see commit c5c46f59 ("x86/entry: Add new,
comprehensible entry and exit handlers written in C").

This change exposes a pre-existing bug on the older tilepro platform;
the singlestep processing is done last, but on tilepro (unlike tilegx)
we enable interrupts while doing that processing, so we could in
theory miss a signal or other asynchronous event.  A future change
could fix this by breaking the singlestep work into a "prepare"
step done in the main loop, and a "trigger" step done after exiting
the loop.  Since this change is intended as purely a restructuring
change, we call out the bug explicitly now, but don't yet fix it.

The Kconfig for this support is currently:

config IDEPCI_PCIBUS_ORDER
        bool "Probe IDE PCI devices in the PCI bus order (DEPRECATED)"

...meaning that it currently is not being built as a module by anyone.
Lets change the initcall to be the equivalent device_initcall, so that
when reading the driver code, there is no doubt it is builtin-only.

Unlike other similar changes, we leave the module.h header to be
included since this code interacts with other drivers and needs to
know what a struct module is.

Back in the day we used to just say this code was root only so it was
ok that the bounds checking was sloppy.  These days it annoys static
checkers so we fix it.

In the original code "c > INT_MAX" was never true since "c" was an int.
I am not sure what was intended so I left it alone.  But because I made
"c" unsigned it means we don't have a warning any more.

The second warning is that we cap "i" but allow negatives leading to an
underflow of the ide_disks_chs[] array.  The third set of warnings is
because these values come from the user and we cap most of the upper
bounds but allow negative values.  Negative cylinders doesn't make
sense.

It was seen that defective configurations of openvswitch could overwrite
the STACK_END_MAGIC and cause a hard crash of the kernel because of too
many recursions within ovs.

This problem arises due to the high stack usage of openvswitch. The rest
of the kernel is fine with the current limit of 10 (RECURSION_LIMIT).

We use the already existing recursion counter in ovs_execute_actions to
implement an upper bound of 5 recursions.

Instead of error-handling on every emit() in JIT, we add a new

running JITed code at run-time only to trap due to AARCH64_BREAK_FAULT.

Pull parsic updates from Helge Deller:
 "This patchset includes two major fixes which are both scheduled for
  stable:

  First, __ARCH_SI_PREAMBLE_SIZE was defined with a wrong value.
  Second, huge page pte and TLB changes needed protection with a
  spinlock.  Other than that there are just some trivial optimizations
  and cleanups"

Merge tag 'drm-intel-next-fixes-2016-01-14' of git://anongit.freedesktop.org/drm-intel into drm-next

misc i915 fixes all over the place.

* tag 'drm-intel-next-fixes-2016-01-14' of git://anongit.freedesktop.org/drm-intel:
  drm/i915/gen9: Set PIN_ZONE_4G end to 4GB - 1 page
  drm/i915: Widen return value for reservation_object_wait_timeout_rcu to long.
  drm/i915: intel_hpd_init(): Fix suspend/resume reprobing

  drm/i915: Move Braswell stop_machine GGTT insertion workaround

Since your main drm-next pull isn't out of the door yet I figured I might
as well flush out drm-misc instead of delaying for 4.6. It's really just
random stuff all over, biggest thing probably connector_mask tracking from
Maarten.
