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.

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. Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Cc: "David S.

In ocfs2 direct read/write, OCFS2_IOCB_SEM lock type is used to protect inode->i_alloc_sem rw semaphore lock in the earlier kernel version.

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.

arm64 updates for 4.2, mostly refactoring/clean-up:
- CPU ops and PSCI (Power State Coordination Interface) refactoring
following the merging of the arm64 ACPI support, together with
handling of Trusted (secure) OS instances
- Using fixmap for permanent FDT mapping, removing the initial dtb
placement requirements (within 512MB from the start of the kernel
image). This required moving the FDT self reservation out of the
memreserve processing
- Idmap (1:1 mapping used for MMU on/off) handling clean-up
- Removing flush_cache_all() - not safe on ARM unless the MMU is off.
Last stages of CPU power down/up are handled by firmware already
- "Alternatives" (run-time code patching) refactoring and support for
immediate branch patching, GICv3 CPU interface access
- User faults handling clean-up
And some fixes:
- Fix for VDSO building with broken ELF toolchains
- Fixing another case of init_mm.pgd usage for user mappings (during
ASID roll-over broadcasting)
- Fix for FPSIMD reloading after CPU hotplug
- Fix for missing syscall trace exit
- Workaround for .inst asm bug
- Compat fix for switching the user tls tpidr_el0 register

The bulk of the changes here is for x86. And for once it's not
for silicon that no one owns: these are really new features for
everyone.
* ARM: several features are in progress but missed the 4.2 deadline.
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.

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.

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.

spi: Updates for v4.2
No framework updates for the SPI API this time around aside from one
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.
- DMA support for the bcm2835 controller.

regmap: Fixes for v4.2
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.

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.

This is the big bulk of GPIO changes queued for the v4.2
kernel series:
- A big set of cleanups to the aged sysfs interface from
Johan Hovold. To get these in, v4.1-rc3 was merged into
the tree as the first patch in that series had to go
into stable. This makes the locking much more fine-grained
(get rid of the "big GPIO lock(s)" and store states in the
GPIO descriptors.
- Rename gpiod_[g|s]et_array() to gpiod_[g|s]et_array_value()
to avoid confusions.
- New drivers for:
- NXP LPC18xx (currently LPC1850)
- NetLogic XLP
- Broadcom STB SoC's
- Axis ETRAXFS
- Zynq Ultrascale+ (subdriver)
- ACPI:
- Make it possible to retrieve GpioInt resources from
a GPIO device using acpi_dev_gpio_irq_get()
- Merge some dependent I2C changes exploiting this.
- Support the ARM X-Gene GPIO standby driver.
- Make it possible for the generic GPIO driver to read
back the value set registers to reflect current
status.
- Loads of OMAP IRQ handling fixes.
- Incremental improvements to Kona, max732x, OMAP, MXC, RCAR,
PCA953x, STP-XWAY, PCF857x, Crystalcove, TB10x.
- Janitorial (contification, checkpatch cleanups)
