53ee983378 Staging driver patches for 3.17-rc1 
Here's the big pull request for the staging driver tree for 3.17-rc1.
 
 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
 as the usual IIO driver updates and additions.
 
 All of this has been in the linux-next tree for a while.

b8c0aa46b3 This pull request has a lot of work done. The main thing is the changes 
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.

  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

  trace_seq() code, and other various small fixes and clean ups to
  ftrace and tracing"

c7ed326fa7 The big change here is the rewrite of config-bisect. The old way never 
worked properly as it assumed the bad config was a subset of the good
 config, and just found the config that would break the build.
 
 The new way does a diff of the bad config verses the good config and makes
 the similar until it finds that one config works and the other does not
 and reports the config that makes that difference. The two configs do
 not need to be related. It is much more useful now.

e4ca4308c0 The clock framework changes for 3.17 are mostly additions of new clock 
drivers and fixes/enhancements to existing clock drivers. There are also
 some non-critical fixes and improvements to the framework core.
 
 Changes to the clock framework core include:
 * improvements to printks on errors
 * flattening the previously hierarchal structure of per-clock entries
   in debugfs
 * allow per-clock debugfs entries that are specific to a particular
   clock driver
 * configure initial clock parent and/or initial clock rate from Device
   Tree
 * several feature enhancements to the composite clock type
 * misc fixes
 
 New clock drivers added include:
 * TI Palmas PMIC
 * Allwinner A23 SoC
 * Qualcomm APQ8084 and IPQ8064 SoCs
 * Rockchip rk3188, rk3066 and rk3288 SoCs
 * STMicroelectronics STiH407 SoC
 * Cirrus Logic CLPS711X SoC
 
 Many fixes, feature enhancements and further clock tree support for
 existing clock drivers also were merged, such as Samsung's "ARMCLK down"
 power saving feature for their Exynos4 & Exynos5 SoCs.

 "Mostly changes to get the v2 interface ready.  The core features are
  mostly ready now and I think it's reasonable to expect to drop the
  devel mask in one or two devel cycles at least for a subset of

   - 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.

   - preventing userspace from trapping into kgdb.
   - fixing a preemption issue in the Intel iwmmxt code.

6bf755db4d ARM: 8124/1: don't enter kgdb when userspace executes a kgdb break instruction 
The kgdb breakpoint hooks (kgdb_brk_fn and kgdb_compiled_brk_fn)
should only be entered when a kgdb break instruction is executed
from the kernel. Otherwise, if kgdb is enabled, a userspace program
can cause the kernel to drop into the debugger by executing either
KGDB_BREAKINST or KGDB_COMPILED_BREAK.

Add a note about the usage of the identity mapping; we do not support
accesses outside of the identity map region and kernel image while a
CPU is using the identity map.  This is because the identity mapping
may overwrite vmalloc space, IO mappings, the vectors pages, etc.
