fe4ba3c343 watchdog: add watchdog_cpumask sysctl to assist nohz 
Change the default behavior of watchdog so it only runs on the
housekeeping cores when nohz_full is enabled at build and boot time.
Allow modifying the set of cores the watchdog is currently running on
with a new kernel.watchdog_cpumask sysctl.

In the current system, the watchdog subsystem runs a periodic timer that
schedules the watchdog kthread to run.  However, nohz_full cores are
designed to allow userspace application code running on those cores to
have 100% access to the CPU.  So the watchdog system prevents the
nohz_full application code from being able to run the way it wants to,
thus the motivation to suppress the watchdog on nohz_full cores, which
this patchset provides by default.

However, if we disable the watchdog globally, then the housekeeping
cores can't benefit from the watchdog functionality.  So we allow
disabling it only on some cores.  See Documentation/lockup-watchdogs.txt
for more information.

b5242e98c1 smpboot: allow excluding cpus from the smpboot threads 
This patch series allows the watchdog to run by default only on the
housekeeping cores when nohz_full is in effect; this seems to be a good
compromise short of turning it off completely (since the nohz_full cores
can't tolerate a watchdog).

To provide customizability, we add /proc/sys/kernel/watchdog_cpumask so
that the set of cores running the watchdog can be tuned to different
values after bootup.

To implement this customizability, we add a new
smpboot_update_cpumask_percpu_thread() API to the smpboot_thread
subsystem that lets us park or unpark "unwanted" threads.

And now that threads can be parked for long periods of time, we tweak the
/proc/<pid>/stat and /proc/<pid>/status code so parked threads aren't
reported as running, which is otherwise confusing.

This patch (of 3):

This change allows some cores to be excluded from running the
smp_hotplug_thread tasks.  The following commit to update
kernel/watchdog.c to use this functionality is the motivating example, and
more information on the motivation is provided there.

A new smp_hotplug_thread field is introduced, "cpumask", which is cpumask
field managed by the smpboot subsystem that indicates whether or not the
given smp_hotplug_thread should run on that core; the cpumask is checked
when deciding whether to unpark the thread.

To limit the cpumask to less than cpu_possible, you must call
smpboot_update_cpumask_percpu_thread() after registering.

8c07a308ec sparc: use for_each_sg() 
This replaces the plain loop over the sglist array with for_each_sg()
macro which consists of sg_next() function calls.  Since sparc does select
ARCH_HAS_SG_CHAIN, it is necessary to use for_each_sg() in order to loop
over each sg element.  This also help find problems with drivers that do
not properly initialize their sg tables when CONFIG_DEBUG_SG is enabled.

099768b0c6 ocfs2: remove BUG_ON(!empty_extent) in __ocfs2_rotate_tree_left() 
ocfs2_rotate_tree_left() calls __ocfs2_rotate_tree_left() for left
rotation while non-rightmost path containing an empty extent in the leaf
block.  __ocfs2_rotate_tree_left() returns -EAGAIN if right subtree having an
empty extent and pass the empty_extent_path to caller.  The caller
ocfs2_rotate_tree_left() will restart rotation from the returned path.

It will trigger the BUG_ON(!ocfs2_is_empty_extent) when the et on disk
is as follows:

eb0 is the leaf block of path(say path_a) passed to
ocfs2_rotate_tree_left, which has an empty rec[0].

eb1 is the leaf block of path(say path_b) that just right to path_a, which
has no empty record.

eb2 is the leaf block of path(say path_c) that just right to path_b, which
has an empty rec[0].  And path_c is also the rightmost path.

Now we want to remove the empty rec[0] in eb0:

ocfs2_rotate_tree_left:
  -> call __ocfs2_rotate_tree_left with path_a as its input *path*
    -> call ocfs2_rotate_subtree_left with path_a as its input
       *left_path* and path_b as its input *right_path*. it will move
       rec[0] in eb1 to eb0, and rec[0] in eb0 is not empty now.
    -> continue to call ocfs2_rotate_subtree_left with path_b as its
       input *left_path* and path_c as its input *right_path*, and
       return -EAGAIN because eb2 has an empty rec[0]
  -> call __ocfs2_rotate_tree_left with path_c as it input, rotate all
     records in eb2 to left and return 0.
  -> call __ocfs2_rotate_tree_left with path_a as its input, and triggers
     the BUG_ON(!ocfs2_is_empty_extent) as the rec[0] in eb0 is not empty.

So the BUG_ON() should be removed and return 0 if rec[0] is no longer an
empty extent.

 - Simplify the mlog macro moving the and/or logic and level code into

for silicon that no one owns: these are really new features for
 everyone.

 So here is just a smattering of bug fixes, plus enabling the VFIO
 integration.
 
 * s390: Some fixes/refactorings/optimizations, plus support for
 2GB pages.
 
 * x86: 1) host and guest support for marking kvmclock as a stable
 scheduler clock. 2) support for write combining. 3) support for
 system management mode, needed for secure boot in guests. 4) a bunch
 of cleanups required for 2+3.  5) support for virtualized performance
 counters on AMD; 6) legacy PCI device assignment is deprecated and
 defaults to "n" in Kconfig; VFIO replaces it.  On top of this there are
 also bug fixes and eager FPU context loading for FPU-heavy guests.
 
 * Common code: Support for multiple address spaces; for now it is
 used only for x86 SMM but the s390 folks also have plans.
 
 There are some x86 conflicts, one with the rc8 pull request and
 the rest with Ingo's FPU rework.

6eae81a5e2 IOMMU Updates for Linux v4.2 
This time with bigger changes than usual:
 
 	* A new IOMMU driver for the ARM SMMUv3. This IOMMU is pretty
 	  different from SMMUv1 and v2 in that it is configured through
 	  in-memory structures and not through the MMIO register region.
 	  The ARM SMMUv3 also supports IO demand paging for PCI devices
 	  with PRI/PASID capabilities, but this is not implemented in
 	  the driver yet.
 
 	* Lots of cleanups and device-tree support for the Exynos IOMMU
 	  driver. This is part of the effort to bring Exynos DRM support
 	  upstream.
 
 	* Introduction of default domains into the IOMMU core code. The
 	  rationale behind this is to move functionalily out of the
 	  IOMMU drivers to common code to get to a unified behavior
 	  between different drivers.
 	  The patches here introduce a default domain for iommu-groups
 	  (isolation groups). A device will now always be attached to a
 	  domain, either the default domain or another domain handled by
 	  the device driver. The IOMMU drivers have to be modified to
 	  make use of that feature. So long the AMD IOMMU driver is
 	  converted, with others to follow.
 
 	* Patches for the Intel VT-d drvier to fix DMAR faults that
 	  happen when a kdump kernel boots. When the kdump kernel boots
 	  it re-initializes the IOMMU hardware, which destroys all
 	  mappings from the crashed kernel. As this happens before
 	  the endpoint devices are re-initialized, any in-flight DMA
 	  causes a DMAR fault. These faults cause PCI master aborts,
 	  which some devices can't handle properly and go into an
 	  undefined state, so that the device driver in the kdump kernel
 	  fails to initialize them and the dump fails.
 	  This is now fixed by copying over the mapping structures (only
 	  context tables and interrupt remapping tables) from the old
 	  kernel and keep the old mappings in place until the device
 	  driver of the new kernel takes over. This emulates the the
 	  behavior without an IOMMU to the best degree possible.
 
 	* A couple of other small fixes and cleanups.

  Core:
   - fix mtd->usecount race conditions (BUG_ON())

   - switch to modern PM ops

  Other:
   - CFI: save code space by de-inlining large functions

   - clean up some partition parser selection code across several
     drivers

   - various miscellaneous changes, mostly minor"

7fe0bf908d regulator: Updates for v4.2 
Another fairly quiet release, some new drivers with generic handling for
 minor features but nothing that makes a substantial difference outside
 of the subsystem or for most boards:
 
  - Support for a bunch of new parameters which are present on enough
    regulators to be worth having generic handling for in the framework.
  - Fixes for some issues with printing constraints during boot which
    should probably have gone in for v4.1 but didn't.
  - New drivers for Dialog DA9062, Maxim MAX77621 and Qualcomm SPMI regulators.

 small fix, just driver improvments.  Some highlights include:
 
  - New driver support for CSR USP, Mikrotik RB4xx and Zynq GQSPI
    controllers.
  - Modernisation of the OMAP McSPI controller driver, moving it to
    current APIs to enable support for a wider range of client drivers.

As well as a few fixes and updates for API changes there's two new
 features for the API:
 
  - Better support for handling a reset of the underlying hardware,
    marking the register map as needing a resync to the device when
    we need to do that automatically.
  - Support for querying the size and stride of the register map,
    allowing higher level frameworks to configure themselves more
    readily.

acd53127c4 SCSI misc on 20150622 
This is the usual grab bag of driver updates (lpfc, hpsa,
 megaraid_sas, cxgbi, be2iscsi) plus an assortment of minor updates.
 There are also one new driver: the Cisco snic; the advansys driver has
 been rewritten to get rid of the warning about converting it to the
 DMA API, the tape statistics patch got in and finally, there's a
 resuffle of SCSI header files to separate more cleanly initiator from
 target mode (and better share the common definitions).

2ad7b44f5d Merge branch 'for-linus-clk' of git://ftp.arm.linux.org.uk/~rmk/linux-arm 
Pull clkdev updates from Russell King:
 "This series addresses some breakage in clkdev caused by a previous
  patch set from the clk tree which introduced per-user clk structures.
  This basically renamed the existing 'struct clk' to 'struct clk_hw',
  and introduced a new 'struct clk'.

  This change will break anyone using clk_add_alias() with the common
  clk code enabled.  Thankfully, the intersection of users of
  clk_add_alias() and those using the common clk code is practically
  zero, but this is something which should be fixed to keep the code
  sane.

  The problem is that clk_add_alias() does this:

        r = clk_get(...);
        l = clkdev_alloc(r, ...);
        clk_put(...);

  which causes the alias to store a pointer to 'r', which has been
  freed.

  The original patch set tried to work around this problem incorrectly -
  at clk_get() time, it tried to convert the struct clk to a struct
  clk_hw, and then creating a new struct clk from that.  Clearly, if the
  original struct clk has been freed, then we have a use-after-free bug.

  We have other places in the tree which do something similar, so this
  series also addresses those locations too.

  This series addresses this problem by converting clkdev to store and
  use the clk_hw pointer.  This allows clk_get() to only have to create
  it's per-user struct clk from the clk_hw.  We can also get to the
  desired clk_hw at clk_add_alias() or clk lookup creation time, when
  the struct clk is "alive".

  We also perform some cleanups of the code:

   - replacing looped calls to clkdev_add() with clkdev_add_table()

   - replacing open-coded lookup allocation (which should have been
     using clkdev_alloc()) and subsequent clkdev_add() with
     clkdev_create()

   - replacing open-coded clk_add_alias() with clk_add_alias()"

Pull power management and ACPI updates from Rafael Wysocki:
 "The rework of backlight interface selection API from Hans de Goede
  stands out from the number of commits and the number of affected
  places perspective.  The cpufreq core fixes from Viresh Kumar are
  quite significant too as far as the number of commits goes and because
  they should reduce CPU online/offline overhead quite a bit in the
  majority of cases.

  From the new featues point of view, the ACPICA update (to upstream
  revision 20150515) adding support for new ACPI 6 material to ACPICA is
  the one that matters the most as some new significant features will be
  based on it going forward.  Also included is an update of the ACPI
  device power management core to follow ACPI 6 (which in turn reflects
  the Windows' device PM implementation), a PM core extension to support
  wakeup interrupts in a more generic way and support for the ACPI _CCA
  device configuration object.

  The rest is mostly fixes and cleanups all over and some documentation
  updates, including new DT bindings for Operating Performance Points.

  There is one fix for a regression introduced in the 4.1 cycle, but it
  adds quite a number of lines of code, it wasn't really ready before
  Thursday and you were on vacation, so I refrained from pushing it on
  the last minute for 4.1.

Pull livepatching fixes from Jiri Kosina:

 - symbol lookup locking fix, from Miroslav Benes

 - error handling improvements in case of failure of the module coming
   notifier, from Minfei Huang

 - we were too pessimistic when kASLR has been enabled on x86 and were
   dropping address hints on the floor unnecessarily in such case.  Fix
   from Jiri Kosina

 - a few other small fixes and cleanups

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/livepatching:
  livepatch: add module locking around kallsyms calls
  livepatch: annotate klp_init() with __init
  livepatch: introduce patch/func-walking helpers
  livepatch: make kobject in klp_object statically allocated
  livepatch: Prevent patch inconsistencies if the coming module notifier fails
  livepatch: match return value to function signature
  x86: kaslr: fix build due to missing ALIGN definition
  livepatch: x86: make kASLR logic more accurate

Pull PCMCIA update from Dominik Brodowski:
 "A few PCMCIA fixes and cleanups are available in the PCMCIA tree.

  Most of them are trivial and self-explanatory.  Of particular note are
  the last three patches which add an important hardware quirk for
  Toshiba ToPIC95 sockets (or BIOS breakage on systems with these
  sockets), fix resource leaks in yenta_socket enable/disable call
  paths, and fix a regression caused by patch 1c6c9b1d9d since v4.0.

  Alan stated he is OK with me pushing this patch upstream.  Once it
  works out well in your tree, I will push it to stable for 4.0/4.1 as
  well"
