- Make it clear that the `node' arg refers to memory allocations only:
kthread_create_on_node() does not pin the new thread to that node's
CPUs.
- Encourage the use of NUMA_NO_NODE.
[nzimmer@sgi.com: use NUMA_NO_NODE in kthread_create() also]

Tony Luck found on his setup, if memory block size 512M will cause crash
during booting.
BUG: unable to handle kernel paging request at ffffea0074000020
IP: get_nid_for_pfn+0x17/0x40
PGD 128ffcb067 PUD 128ffc9067 PMD 0
Oops: 0000 [#1] SMP
Modules linked in:
CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.2.0-rc8 #1
...
Call Trace:
? register_mem_sect_under_node+0x66/0xe0
register_one_node+0x17b/0x240
? pci_iommu_alloc+0x6e/0x6e
topology_init+0x3c/0x95
do_one_initcall+0xcd/0x1f0
The system has non continuous RAM address:
BIOS-e820: [mem 0x0000001300000000-0x0000001cffffffff] usable
BIOS-e820: [mem 0x0000001d70000000-0x0000001ec7ffefff] usable
BIOS-e820: [mem 0x0000001f00000000-0x0000002bffffffff] usable

BIOS-e820: [mem 0x0000002e00000000-0x00000039ffffffff] usable
So there are start sections in memory block not present. For example:
memory block : [0x2c18000000, 0x2c20000000) 512M
first three sections are not present.
The current register_mem_sect_under_node() assume first section is
present, but memory block section number range [start_section_nr,
end_section_nr] would include not present section.
For arch that support vmemmap, we don't setup memmap for struct page
area within not present sections area.
So skip the pfn range that belong to absent section.

ocfs2_file_write_iter() is usng the wrong return value ('written'). This
will cause ocfs2_rw_unlock() be called both in write_iter & end_io,
triggering a BUG_ON.

__generic_file_write_iter()").

node_data for a node.
Commit f9126ab9241f ("memory-hotplug: fix wrong edge when hot add a new
node") hot-added memory range to memblock, after creating pgdat for new
node.
But there is a problem:
add_memory()
|--> hotadd_new_pgdat()
|--> free_area_init_node()
|--> get_pfn_range_for_nid()
|--> find start_pfn and end_pfn in memblock
|--> ......
|--> memblock_add_node(start, size, nid) -------- Here, just too late.
get_pfn_range_for_nid() will find that start_pfn and end_pfn are both 0.
As a result, when adding memory, dmesg will give the following wrong
message.
Initmem setup node 5 [mem 0x0000000000000000-0xffffffffffffffff]
On node 5 totalpages: 0
Built 5 zonelists in Node order, mobility grouping on. Total pages: 32588823
Policy zone: Normal
init_memory_mapping: [mem 0x60000000000-0x607ffffffff]
The solution is simple, just add the memory range to memblock a little
earlier, before hotadd_new_pgdat().

With lockdep support implemented on CRISv32, we get the following splat.
switch_mm() can be called both from the scheduler() (with interrupts
disabled) and from flush_old_exec (via activate_mm()), with interrupts
enabled. Fix it by disabling interrupts in activate_mm(), similar to
powerpc and hexagon.

This reverts commit f895c53f8ace3c3e49ebf9def90e63fc6d46d2bf.
This commit causes a NFSv4 regression in that close()+unlink() can end
up failing. The reason is that we no longer have a guarantee that the
CLOSE has completed on the server, meaning that the subsequent call to
REMOVE may fail with NFS4ERR_FILE_OPEN if the server implements Windows
unlink() semantics.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"There are little changes in core part, but lots of development are
found in drivers, especially ASoC. The diffstat shows regmap-related
changes for a slight API additions / changes, and that's all.
Looking at the code size statistics, the most significant addition is
for Intel Skylake. (Note that SKL support is still underway, the
codec driver is missing.) Also STI controller driver is a major
addition as well as a few new codec drivers.
In HD-audio side, there are fewer changes than the past. The
noticeable change is the support of ELD notification from i915
graphics driver. Thus this pull request carries a few changes in
drm/i915.
Other than that, USB-audio got a rewrite of runtime PM code. It was
initiated by lockdep warning, but resulted in a good cleanup in the
end.
Below are the highlights:
Common:
- Factoring out of AC'97 reset code from ASoC into the core helper
- A few regmap API extensions (in case it's not pulled yet)
ASoC:
- New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek
RT298 and ST STI controllers
- Machine drivers for Rockchip systems with MAX98090 and RT5645 and
RT5650
- Initial driver support for Intel Skylake devices
- Lots of rsnd cleanup and enhancements
- A few DAPM fixes and cleanups
- A large number of cleanups in various drivers (conversion and
standardized to regmap, component) mostly by Lars-Peter and Axel
HD-audio:
- Extended HD-audio core for Intel Skylake controller support
- Quirks for Dell headsets, Alienware 15
- Clean up of pin-based quirk tables for Realtek codecs
- ELD notifier implenetation for Intel HDMI/DP
USB-audio:
- Refactor runtime PM code to make lockdep happier"

[ The Kconfig and Makefile entries got re-sorted alphabetically, and I
handled the conflict with the new Intel integrated IDMA driver by
slightly mis-sorting it on purpose: "IDMA64" got sorted after "IMX" in
order to keep the Intel entries together. I think it might be a good
idea to just rename the IDMA64 config entry to INTEL_IDMA64 to make
the sorting be a true sort, not this mismash.
Also, this merge disables the COMPILE_TEST for the sun4i DMA
controller, because it does not compile cleanly at all. - Linus ]

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v4.3 development
cycle.
Like with GPIO it's a lot of stuff. If my subsystems are any sign of
the overall tempo of the kernel v4.3 will be a gigantic diff.
[ It looks like 4.3 is calmer than 4.2 in most other subsystems, but
we'll see - Linus ]
Core changes:
- It is possible configure groups in debugfs.
- Consolidation of chained IRQ handler install/remove replacing all
call sites where irq_set_handler_data() and
irq_set_chained_handler() were done in succession with a combined
call to irq_set_chained_handler_and_data(). This series was
created by Thomas Gleixner after the problem was observed by
Russell King.
- Tglx also made another series of patches switching
__irq_set_handler_locked() for irq_set_handler_locked() which is
way cleaner.
- Tglx also wrote a good bunch of patches to make use of
irq_desc_get_xxx() accessors and avoid looking up irq_descs from
IRQ numbers. The goal is to get rid of the irq number from the
handlers in the IRQ flow which is nice.
Driver feature enhancements:
- Power management support for the SiRF SoC Atlas 7.
- Power down support for the Qualcomm driver.
- Intel Cherryview and Baytrail: switch drivers to use raw spinlocks
in IRQ handlers to play nice with the realtime patch set.
- Rework and new modes handling for Qualcomm SPMI-MPP.
- Pinconf power source config for SH PFC.
New drivers and subdrivers:
- A new driver for Conexant Digicolor CX92755.
- A new driver for UniPhier PH1-LD4, PH1-Pro4, PH1-sLD8, PH1-Pro5,
ProXtream2 and PH1-LD6b SoC pin control support.
- Reverse-egineered the S/PDIF settings for the Allwinner sun4i
driver.
- Support for Qualcomm Technologies QDF2xxx ARM64 SoCs
- A new Freescale i.mx6ul subdriver.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.3 kernel cycle.
There is quite a lot going on in the GPIO subsystem this merge window,
so the main matter is decribed below.
The hits in other subsystems when making the GPIO flags optional are
all ACKed by their respective subsystem maintainers.
Core changes:
- Root out the wrapper devm_gpiod_get() and gpiod_get() etc versions
of the descriptor calls that did not use the flags argument on the
end. This was around for too long and eventually Uwe Kleine-König
took the time to clean it out and the last users are removed along
with the macros in this tag. In several cases the use of flags
simplifies the code. For this reason we have (ACKed) patches
hitting in DRM, IIO, media, NFC, USB+PHY up until we hammer in the
nail with removing the macros.
- Add a fat document describing how much ready-made GPIO stuff we
have i the kernel to discourage people from reinventing a square
wheel in userspace, as so often happens.
- Create a separate lockdep class for each instance of a GPIO IRQ
chip instead of using one class for all chips, as the current code
will not work with systems with several GPIO chips doing lockdep
debugging.
- Protect against driver unloading also when a GPIO line is only used
as IRQ for the GPIOLIB_IRQCHIP helpers.
- If the GPIO chip has no designated owner, assign the parent device
driver owner as owner.
- Consolidation of chained IRQ handler install/remove replacing all
call sites where irq_set_handler_data() and
irq_set_chained_handler() were done in succession with a combined
call to irq_set_chained_handler_and_data().
This series was created by Thomas Gleixner after the problem was
observed by Russell King.
- Tglx also made another series of patches switching
__irq_set_handler_locked() for irq_set_handler_locked() which is
way cleaner.
- Tglx and Jiang Liu wrote a good bunch of patches to make use of
irq_desc_get_xxx() accessors and avoid looking up irq_descs from
IRQ numbers. The goal is to get rid of the irq number from the
handlers in the IRQ flow which is nice.
- Rob Herring killed off the set_irq_flags() for all GPIO drivers.
This was an ARM specific function that is replaced with the generic
irq_modify_status() where special flags are actually needed.
- When an OF node has a pin range for its GPIOs, return -EPROBE_DEFER
if the pin controller isn't available. Pretty logical, yet needed
to be fixed.
- If a driver using GPIOLIB_IRQCHIP has its own irq_*_resources call
back, then call these instead of the defaults provided by the
GPIOLIB.
- Fix an undocumented ABI hole: named GPIOs were not properly
documented.
Driver improvements:
- Add get_direction() support to the generic GPIO driver, it's
strange that we didn't have that before.
- Make it possible to have input-only GPIO chips using the generic
GPIO driver.
- Clean out platform data support from the Emma Mobile (EM) driver
- Finegrained runtime PM support for the RCAR driver.
- Support r8a7795 (R-car H3) in the RCAR driver.
- Support interrupts on GPIOs 16 thru 31 in the DaVinci driver.
- Some consolidation and new support in the MPC8xxx driver, we now
support MPC5125.
- Preempt-RT-friendly patches: the OMAP, MPC8xxx, drivers uses raw
spinlocks making it work better with the realime patches.
- Interrupt support for the EXTRAXFS GPIO driver.
- Make the ETRAXFS GPIO driver support also ARTPEC-3.
- Interrupt and wakeup support for the BRCMSTB driver, also for
wakeup from S5 cold boot.
- Mask MXC IRQs during suspend.
- Improve OMAP2 GPIO set_debounce() to work according to spec.
- The VF610 driver handles IRQs properly.
New drivers:
- ZTE ZX GPIO driver"
