Here is the big USB driver update for 3.17-rc1.
Loads of gadget driver changes in here, including some big file
movements to make things easier to manage over time. There's also the
usual xhci and uas driver updates, and a handful of other changes in
here. The changelog has the full details.
All of these have been in linux-next for a while.

Lots of things in here, over 2000 patches, but the best part is this:
1480 files changed, 39070 insertions(+), 254659 deletions(-)
Thanks to the great work of Kristina Martšenko, 14 different staging
drivers have been removed from the tree as they were obsolete and no one
was willing to work on cleaning them up. Other than the driver
removals, loads of cleanups are in here (comedi, lustre, etc.) as well

to the ftrace function callback infrastructure. It's introducing a
way to allow different functions to call directly different trampolines
instead of all calling the same "mcount" one.
The only user of this for now is the function graph tracer, which always
had a different trampoline, but the function tracer trampoline was called
and did basically nothing, and then the function graph tracer trampoline
was called. The difference now, is that the function graph tracer
trampoline can be called directly if a function is only being traced by
the function graph trampoline. If function tracing is also happening on
the same function, the old way is still done.
The accounting for this takes up more memory when function graph tracing
is activated, as it needs to keep track of which functions it uses.
I have a new way that wont take as much memory, but it's not ready yet
for this merge window, and will have to wait for the next one.
Another big change was the removal of the ftrace_start/stop() calls that
were used by the suspend/resume code that stopped function tracing when
entering into suspend and resume paths. The stop of ftrace was done
because there was some function that would crash the system if one called
smp_processor_id()! The stop/start was a big hammer to solve the issue
at the time, which was when ftrace was first introduced into Linux.
Now ftrace has better infrastructure to debug such issues, and I found
the problem function and labeled it with "notrace" and function tracing
can now safely be activated all the way down into the guts of suspend
and resume.
Other changes include clean ups of uprobe code.
Clean up of the trace_seq() code.
And other various small fixes and clean ups to ftrace and tracing.

"Mostly changes to get the v2 interface ready. The core features are

- cgroup added a controller dependency mechanism so that block cgroup
can depend on memory cgroup. This will be used to finally support
IO provisioning on the writeback traffic, which is currently being
implemented.
- The v2 interface now uses a separate table so that the interface
files for the new interface are explicitly declared in one place.
Each controller will explicitly review and add the files for the
new interface.
- cpuset is getting ready for the hierarchical behavior which is in
the similar style with other controllers so that an ancestor's
configuration change doesn't change the descendants' configurations
irreversibly and processes aren't silently migrated when a CPU or
node goes down.

the multiple hierarchies"

I know we've come full-circle here back to a tunable, but this
new one is *WAY* simpler. I challenge anyone to describe in one

If we are flushing more pages than the ceiling, we use
the full flush, otherwise we use per-page flushes.

- Remove unnecessary OOM messages for all extcon device drivers
3. Fix minor issue of extcon core
- Re-order the sequence of extcon device driver in Kconfig/Makefile alphabitically
- Set parent device of extcon device automatically using devm_extcon_dev_allocate()
4. Fix MAX77693 driver
- This patchset has dependency on MFD/Regulator/Extcon. So, Lee Jones

qcom clock changes for 3.17
These patches add support for a handful of Qualcomm's SoC clock
controllers: APQ8084 gcc and mmcc, IPQ8064 gcc, and APQ8064.
There's also a small collection of bug fixes that aren't critical
-rc worthy regressions because the consumer drivers aren't present
or using the buggy clocks and one optimization for HDMI.
This patch adds helper functions to configure clock parents and rates
as specified through 'assigned-clock-parents', 'assigned-clock-rates'
DT properties for a clock provider or clock consumer device.
The helpers are now being called by the bus code for the platform, I2C
and SPI busses, before the driver probing and also in the clock core
after registration of a clock provider.

New functionality
* A new modifier to indicate that a rotation is relative to either
true or magnetic north. This is to be used by some magnetometers
that provide data in this way.
* hid magnetometer now supports output rotations from various variants on
North
* HMC5843 driver converted to regmap and reworked to allow easy support
of other similar devices. Support for HMC5983 added via both i2c and SPI.
* Rework of Exynos driver to simplify extension to support more devices.
* Addition of support for the Exynos3250 ADC (which requires an additional
clock) Support for quite a few more devices on its way.
Cleanups
* ad7997 - a number of cleanups and tweaks to how the events are controlled
to make it more intuitive.
* kxcjk - cleanups and minor fixes for this new driver.

This patch allows support for 3 levels of page tables with 64KB page
configuration allowing 48-bit VA space. The pgd is no longer a full
PAGE_SIZE (PTRS_PER_PGD is 64) and (swapper|idmap)_pg_dir are not fully
populated (pgd_alloc falls back to kzalloc).

Rather than guessing what the maximum vmmemap space should be, this
patch allows the calculation based on the VA_BITS and sizeof(struct
page). The vmalloc space extends to the beginning of the vmemmap space.
Since the virtual kernel memory layout now depends on the build
configuration, this patch removes the detailed description in
Documentation/arm64/memory.txt in favour of information printed during
kernel booting.

The default cache operations for ARM64 were changed during 3.15.
To use coherent operations a "dma-coherent" device tree property
is required. If that property is not present in the device tree
node then the non-coherent operations are assigned for the device.
Add support to the ccp driver to assign the AXI DMA cache settings
based on whether the "dma-coherent" property is present in the device
node. If present, use settings that work with the caches. If not
present, use settings that do not look at the caches.
