mm/bootmem: remove duplicated declaration of __free_pages_bootmem()
The __free_pages_bootmem is used internally by MM core and already defined in internal.h. So, remove duplicated declaration.

introduce for_each_thread() to replace the buggy while_each_thread()
while_each_thread() and next_thread() should die, almost every lockless usage is wrong. 1. Unless g == current, the lockless while_each_thread() is not safe. while_each_thread(g, t) can loop forever if g exits, next_thread() can't reach the unhashed thread in this case. Note that this can happen even if g is the group leader, it can exec. 2. Even if while_each_thread() itself was correct, people often use it wrongly. It was never safe to just take rcu_read_lock() and loop unless you verify that pid_alive(g) == T, even the first next_thread() can point to the already freed/reused memory. This patch adds signal_struct->thread_head and task->thread_node to create the normal rcu-safe list with the stable head. The new for_each_thread(g, t) helper is always safe under rcu_read_lock() as long as this task_struct can't go away. Note: of course it is ugly to have both task_struct->thread_node and the old task_struct->thread_group, we will kill it later, after we change the users of while_each_thread() to use for_each_thread(). Perhaps we can kill it even before we convert all users, we can reimplement next_thread(t) using the new thread_head/thread_node. But we can't do this right now because this will lead to subtle behavioural changes. For example, do/while_each_thread() always sees at least one task, while for_each_thread() can do nothing if the whole thread group has died. Or thread_group_empty(), currently its semantics is not clear unless thread_group_leader(p) and we need to audit the callers before we can change it. So this patch adds the new interface which has to coexist with the old one for some time, hopefully the next changes will be more or less straightforward and the old one will go away soon.

mm/rmap: extend rmap_walk_xxx() to cope with different cases
There are a lot of common parts in traversing functions, but there are also a little of uncommon parts in it. By assigning proper function pointer on each rmap_walker_control, we can handle these difference correctly. Following are differences we should handle. 1. difference of lock function in anon mapping case 2. nonlinear handling in file mapping case 3. prechecked condition: checking memcg in page_referenced(), checking VM_SHARE in page_mkclean() checking temporary vma in try_to_unmap() 4. exit condition: checking page_mapped() in try_to_unmap() So, in this patch, I introduce 4 function pointers to handle above differences.

memblock, mem_hotplug: make memblock skip hotpluggable regions if needed
Linux kernel cannot migrate pages used by the kernel. As a result, hotpluggable memory used by the kernel won't be able to be hot-removed. To solve this problem, the basic idea is to prevent memblock from allocating hotpluggable memory for the kernel at early time, and arrange all hotpluggable memory in ACPI SRAT(System Resource Affinity Table) as ZONE_MOVABLE when initializing zones. In the previous patches, we have marked hotpluggable memory regions with MEMBLOCK_HOTPLUG flag in memblock.memory. In this patch, we make memblock skip these hotpluggable memory regions in the default top-down allocation function if movable_node boot option is specified.

So that we could control memblock allocator not to allocte hotpluggable memory for the kernel later.

memblock, numa: introduce flags field into memblock
There is no flag in memblock to describe what type the memory is.
Sometimes, we may use memblock to reserve some memory for special usage.
And we want to know what kind of memory it is. So we need a way to
In hotplug environment, we want to reserve hotpluggable memory so the
kernel won't be able to use it. And when the system is up, we have to
free these hotpluggable memory to buddy. So we need to mark these
memory first.
In order to do so, we need to mark out these special memory in memblock.
In this patch, we introduce a new "flags" member into memblock_region:
struct memblock_region {
phys_addr_t base;
phys_addr_t size;
unsigned long flags; /* This is new. */
#ifdef CONFIG_HAVE_MEMBLOCK_NODE_MAP
int nid;
#endif
};
This patch does the following things:
1) Add "flags" member to memblock_region.
2) Modify the following APIs' prototype:
memblock_add_region()
memblock_insert_region()
3) Add memblock_reserve_region() to support reserve memory with flags, and keep
memblock_reserve()'s prototype unmodified.
4) Modify other APIs to support flags, but keep their prototype unmodified.
The idea is from Wen Congyang <wency@cn.fujitsu.com> and Liu Jiang <jiang.liu@huawei.com>.

mm: add overcommit_kbytes sysctl variable
Some applications that run on HPC clusters are designed around the availability of RAM and the overcommit ratio is fine tuned to get the maximum usage of memory without swapping. With growing memory, the 1%-of-all-RAM grain provided by overcommit_ratio has become too coarse for these workload (on a 2TB machine it represents no less than 20GB).

mm: create a separate slab for page->ptl allocation
If DEBUG_SPINLOCK and DEBUG_LOCK_ALLOC are enabled spinlock_t on x86_64 is 72 bytes. For page->ptl they will be allocated from kmalloc-96 slab, so we loose 24 on each. An average system can easily allocate few tens thousands of page->ptl and overhead is significant. Let's create a separate slab for page->ptl allocation to solve this. To make sure that it really works this time, some numbers from my test machine (just booted, no load): Before: # grep '^\(kmalloc-96\|page->ptl\)' /proc/slabinfo kmalloc-96 31987 32190 128 30 1 : tunables 120 60 8 : slabdata 1073 1073 92 After: # grep '^\(kmalloc-96\|page->ptl\)' /proc/slabinfo page->ptl 27516 28143 72 53 1 : tunables 120 60 8 : slabdata 531 531 9 kmalloc-96 3853 5280 128 30 1 : tunables 120 60 8 : slabdata 176 176 0 Note that the patch is useful not only for debug case, but also for PREEMPT_RT, where spinlock_t is always bloated.

mm: get rid of unnecessary pageblock scanning in setup_zone_migrate_reserve
Yasuaki Ishimatsu reported memory hot-add spent more than 5 _hours_ on
9TB memory machine since onlining memory sections is too slow. And we
found out setup_zone_migrate_reserve spent >90% of the time.
The problem is, setup_zone_migrate_reserve scans all pageblocks
unconditionally, but it is only necessary if the number of reserved
block was reduced (i.e. memory hot remove).
Moreover, maximum MIGRATE_RESERVE per zone is currently 2. It means
that the number of reserved pageblocks is almost always unchanged.
This patch adds zone->nr_migrate_reserve_block to maintain the number of
MIGRATE_RESERVE pageblocks and it reduces the overhead of
setup_zone_migrate_reserve dramatically. The following table shows time
of onlining a memory section.

mm: tail page refcounting optimization for slab and hugetlbfs
This skips the _mapcount mangling for slab and hugetlbfs pages. The main trouble in doing this is to guarantee that PageSlab and PageHeadHuge remains constant for all get_page/put_page run on the tail of slab or hugetlbfs compound pages. Otherwise if they're set during get_page but not set during put_page, the _mapcount of the tail page would underflow. PageHeadHuge will remain true until the compound page is released and enters the buddy allocator so it won't risk to change even if the tail page is the last reference left on the page. PG_slab instead is cleared before the slab frees the head page with put_page, so if the tail pin is released after the slab freed the page, we would have a problem. But in the slab case the tail pin cannot be the last reference left on the page. This is because the slab code is free to reuse the compound page after a kfree/kmem_cache_free without having to check if there's any tail pin left. In turn all tail pins must be always released while the head is still pinned by the slab code and so we know PG_slab will be still set too.

Currently we don't clobber page_tail->first_page during split_huge_page, so compound_trans_head can be set to compound_head without adverse effects, and this mostly optimizes away a smp_rmb. It looks worthwhile to keep around the implementation that doesn't relay on page_tail->first_page not to be clobbered, because it would be necessary if we'll decide to enforce page->private to zero at all times whenever PG_private is not set, also for anonymous pages. For anonymous pages enforcing such an invariant doesn't matter as anonymous pages don't use page->private so we can get away with this microoptimization.

mm: hugetlbfs: Add some VM_BUG_ON()s to catch non-hugetlbfs pages
Dave Jiang reported that he was seeing oopses when running NUMA systems and default_hugepagesz=1G. I traced the issue down to migrate_page_copy() trying to use the same code for hugetlb pages and transparent hugepages. It should not have been trying to pass thp pages in there. So, add some VM_BUG_ON()s for the next hapless VM developer that tries the same thing.

mm: Make {,set}page_address() static inline if WANT_PAGE_VIRTUAL
{,set}page_address() are macros if WANT_PAGE_VIRTUAL. If
!WANT_PAGE_VIRTUAL, they're plain C functions.
If someone calls them with a void *, this pointer is auto-converted to
struct page * if !WANT_PAGE_VIRTUAL, but causes a build failure on
architectures using WANT_PAGE_VIRTUAL (arc, m68k and sparc64):
drivers/md/bcache/bset.c: In function `__btree_sort':
drivers/md/bcache/bset.c:1190: warning: dereferencing `void *' pointer
drivers/md/bcache/bset.c:1190: error: request for member `virtual' in something not a structure or union
Convert them to static inline functions to fix this. There are already
plenty of users of struct page members inside <linux/mm.h>, so there's
no reason to keep them as macros.

fsnotify: do not share events between notification groups
Currently fsnotify framework creates one event structure for each notification event and links this event into all interested notification groups. This is done so that we save memory when several notification groups are interested in the event. However the need for event structure shared between inotify & fanotify bloats the event structure so the result is often higher memory consumption. Another problem is that fsnotify framework keeps path references with outstanding events so that fanotify can return open file descriptors with its events. This has the undesirable effect that filesystem cannot be unmounted while there are outstanding events - a regression for inotify compared to a situation before it was converted to fsnotify framework. For fanotify this problem is hard to avoid and users of fanotify should kind of expect this behavior when they ask for file descriptors from notified files. This patch changes fsnotify and its users to create separate event structure for each group. This allows for much simpler code (~400 lines removed by this patch) and also smaller event structures. For example on 64-bit system original struct fsnotify_event consumes 120 bytes, plus additional space for file name, additional 24 bytes for second and each subsequent group linking the event, and additional 32 bytes for each inotify group for private data. After the conversion inotify event consumes 48 bytes plus space for file name which is considerably less memory unless file names are long and there are several groups interested in the events (both of which are uncommon). Fanotify event fits in 56 bytes after the conversion (fanotify doesn't care about file names so its events don't have to have it allocated). A win unless there are four or more fanotify groups interested in the event. The conversion also solves the problem with unmount when only inotify is used as we don't have to grab path references for inotify events.

sound updates for 3.14-rc1
It was holiday season, so no wonder that there are little changes in
framework level, although diffstat shows quite many changes spreaded
over sound/* directories. Most of changes are cleanups, code
refactoring and fixes.
Some highlights:
- Removal of OSS sleep_on usages by Arnd
- Simplified memalloc helper codes, drop obsoleted features;
now it's built into PCM driver instead of an individual module
- Warn if PCM buffer preallocation fails, which will show page
allocation issues more clearly
- Compress offload API updates for sample rates by Vinod
- PCM glitch workaround on ctxfi emu20k1 by Sarah
- Drop cs46xx DSP blobs, using firmware loader now
- USB-audio quitks for Plantronics Gamecom 780, Creative VF0420,
and Focusrite Saffire 6
HD-audio specifics:
- Standardize Kconfigs of HD-audio codec drivers;
now "make localmodconfig" recognizes configs properly (finally!)
- Parallel PM implementation by Mengdong
- BayleyBay/ValleyView2 board fixups
- Broadwell audio support
- Runtime PM improvement (PantherPoint, etc)
- Quirks: Dell subwooer, Gigabyte mobo jack detection oddity,
Dell AiO click noise fixes, Dell headset mic fixes, etc
- Automatic bind with HDMI codec parser without generic parser
- More AD codec fixes (since 3.12 regression) including the automatic
stereo mix support
- Common Thinkpad ACPI helper for Realtek and Conexant codecs
ASoC specifics:
- Update to the generic DMA code to support deferred probe and managed
resources
- New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090
and Analog Devices AXI I2S and S/PDIF controller IPs
- Device tree support for the simple card, max98090 and cs42l52
- Conversion of the Samsung drivers to native dmaengine, making them
multiplatform compatible and hopefully helping keep them more modern
and up to date.
- More regmap conversions, including a very welcome one for twl6040
from Peter Ujfalusi
- A big overhaul of the DaVinci drivers also from Peter Ujfalusi
- Lots of DMA updates from Lars-Peter
- Improvements to the constraints handling code from Lars-Peter
- A very helpful conversion of the TWL4030 driver to regmap from Peter
- A new driver for the Freescale ESAI controller from Nicolin Chen
- Conversion of some of the drivers to use params_width()
- Extensions to DPCM for use with compressed audio from Liam

"This has been queued and tested for a while. Lots of action here,
like in the GPIO tree, embedded stuff like this is really hot now it
seems. Details in the signed tag. I'm especially happy about the
Qualcomm driver as it is used in such a huge subset of mobile handsets
out there, and these platforms in general need better upstream support
- New driver for the Qualcomm TLMM pin controller and its msm8x74
subdriver.
- New driver for the Broadcom Capri BCM281xx SoC.
- New subdriver for the imx25 pin controller.
- New subdriver for the Tegra124 pin controller.
- Lock GPIO lines as IRQs for select combined pin control and GPIO
drivers for baytrail and sirf.
- Some semi-big refactorings and extenstions to the sirf driver.
- Lots of patching, cleanup and fixing in the Renesas "PFC" driver
and associated subdrivers as usual. It is settling down a little
bit now it seems.
- Minor fixes and incremental updates here and there as usual"

GPIO tree bulk changes for v3.14
A big set this merge window, as we have much going on in
this subsystem. Major changes this time:
- Some core improvements and cleanups to the new GPIO
descriptor API. This seems to be working now so we can
start the exodus to this API, moving gradually away from
the global GPIO numberspace.
- Incremental improvements to the ACPI GPIO core, and move
the few GPIO ACPI clients we have to the GPIO descriptor
API right *now* before we go any further. We actually
managed to contain this *before* we started to litter
the kernel with yet another hackish global numberspace for
the ACPI GPIOs, which is a big win.
- The RFkill GPIO driver and all platforms using it have
been migrated to use the GPIO descriptors rather than
fixed number assignments. Tegra machine has been migrated
as part of this.
- New drivers for MOXA ART, Xtensa GPIO32 and SMSC SCH311x.
Those should be really good examples of how I expect a
nice GPIO driver to look these days.
- Do away with custom GPIO implementations on a major
part of the ARM machines: ks8695, lpc32xx, mv78xx0.
Make a first step towards the same in the horribly
convoluted Samsung S3C include forest. We expect to
continue to clean this up as we move forward.
- Flag GPIO lines used for IRQ on adnp, bcm-kona, em,
intel-mid and lynxpoint.
This makes the GPIOlib core aware that a certain GPIO line
is used for IRQs and can then enforce some semantics such
as disallowing a GPIO line marked as in use for IRQ to be
switched to output mode.
- Drop all use of irq_set_chip_and_handler_name().
The name provided in these cases were just unhelpful
tags like "mux" or "demux".
- Extend the MCP23s08 driver to handle interrupts.
- Minor incremental improvements for rcar, lynxpoint, em
74x164 and msm drivers.
- Some non-urgent bug fixes here and there, duplicate
#includes and that usual kind of cleanups.

mfd: Add LP3943 MFD driver
LP3943 has 16 output pins which can be used as GPIO expander and PWM generator. * Regmap I2C interface for R/W LP3943 registers * Atomic operations for output pin assignment The driver should check whether requested pin is available or not. If the pin is already used, pin request returns as a failure. A driver data, 'pin_used' is checked when gpio_request() and pwm_request() are called. If the pin is available, then pin_used is set. And it is cleared when gpio_free() and pwm_free(). * Device tree support Compatible strings for GPIO and PWM driver. LP3943 platform data is PWM related, so parsing the device tree is implemented in the PWM driver. Signed-off-by: Milo Kim <milo.kim@ti.com> Signed-off-by: Lee Jones <lee.jones@linaro.org> |

TTY/Serial driver patches for 3.14-rc1
Here's the big tty/serial driver pull request for 3.14-rc1 There are a number of n_tty fixes and cleanups, and some serial driver bugfixes, and we got rid of one obsolete driver, making this series remove more lines than added, always a nice surprise. All of these have been in linux-next with no reports of issues.

Staging driver tree patches for 3.14-rc1
Here's the big drivers/staging/ update for 3.14-rc1 Lots and lots of cleanups, IIO driver updates are also mixed in here due to the subsystem still crossing staging and drivers/iio/, and the dwc2 driver is moved out of staging. There's a new driver (rts5208), which ends up making us adding more lines than removing, but overall there was lots of work toward moving code out of here, which was good. All of this has been in linux-next with no reported issues.

Driver core / sysfs patches for 3.14-rc1
Here's the big driver core and sysfs patch set for 3.14-rc1.
There's a lot of work here moving sysfs logic out into a "kernfs" to
allow other subsystems to also have a virtual filesystem with the same
attributes of sysfs (handle device disconnect, dynamic creation /
removal as needed / unneeded, etc. This is primarily being done for
the cgroups filesystem, but the goal is to also move debugfs to it when
it is ready, solving all of the known issues in that filesystem as well.
The code isn't completed yet, but all should be stable now (there is a
big section that was reverted due to problems found when testing.)
There's also some other smaller fixes, and a driver core addition that
allows for a "collection" of objects, that the DRM people will be using
soon (it's in this tree to make merges after -rc1 easier.)
All of this has been in linux-next with no reported issues.
