This file is almost on the standard format. All it needs
to be parsed by Sphinx is to fix its main title and add
a few blank lines.

ReST markup.

d3457c877b kvm: x86: hyperv: make VP_INDEX managed by userspace 
Hyper-V identifies vCPUs by Virtual Processor Index, which can be
queried via HV_X64_MSR_VP_INDEX msr.  It is defined by the spec as a
sequential number which can't exceed the maximum number of vCPUs per VM.
APIC ids can be sparse and thus aren't a valid replacement for VP
indices.

Current KVM uses its internal vcpu index as VP_INDEX.  However, to make
it predictable and persistent across VM migrations, the userspace has to
control the value of VP_INDEX.

This patch achieves that, by storing vp_index explicitly on vcpu, and
allowing HV_X64_MSR_VP_INDEX to be set from the host side.  For
compatibility it's initialized to KVM vcpu index.  Also a few variables
are renamed to make clear distinction betweed this Hyper-V vp_index and
KVM vcpu_id (== APIC id).  Besides, a new capability,
KVM_CAP_HYPERV_VP_INDEX, is added to allow the userspace to skip
attempting msr writes where unsupported, to avoid spamming error logs.

52a5c155cf KVM: async_pf: Let guest support delivery of async_pf from guest mode 
Adds another flag bit (bit 2) to MSR_KVM_ASYNC_PF_EN. If bit 2 is 1,
async page faults are delivered to L1 as #PF vmexits; if bit 2 is 0,
kvm_can_do_async_pf returns 0 if in guest mode.

This is similar to what svm.c wanted to do all along, but it is only
enabled for Linux as L1 hypervisor.  Foreign hypervisors must never
receive async page faults as vmexits, because they'd probably be very
confused about that.

Pull RTC updates from Alexandre Belloni:
 "Here is the pull-request for the RTC subsystem for 4.13.

  Subsystem:

   - expose non volatile RAM using nvmem instead of open coding in many
     drivers. Unfortunately, this option has to be enabled by default to
     not break existing users.

   - rtctest can now test for cutoff dates, showing when an RTC will
     start failing to properly save time and date.

   - new RTC registration functions to remove race conditions in drivers

  Newly supported RTCs:

   - Broadcom STB wake-timer

   - Epson RX8130CE

   - Maxim IC DS1308

   - STMicroelectronics STM32H7

  Drivers:

   - ds1307: use regmap, use nvmem, more cleanups

   - ds3232: temperature reading support

   - gemini: renamed to ftrtc010

   - m41t80: use CCF to expose the clock

7d84120b5b Documentation: ABI: mtd: describe "offset" more precisely 
So far Linux supported only two levels of MTD devices so we didn't need
a very precise description for this sysfs file. With commit
97519dc52b ("mtd: partitions: add support for subpartitions") there
is support for a tree structure so we should have more precise
description. Using "parent" and "flash device" makes it more accurate.

efc479e690 kvm: x86: hyperv: add KVM_CAP_HYPERV_SYNIC2 
There is a flaw in the Hyper-V SynIC implementation in KVM: when message
page or event flags page is enabled by setting the corresponding msr,
KVM zeroes it out.  This is problematic because on migration the
corresponding MSRs are loaded on the destination, so the content of
those pages is lost.

This went unnoticed so far because the only user of those pages was
in-KVM hyperv synic timers, which could continue working despite that
zeroing.

Newer QEMU uses those pages for Hyper-V VMBus implementation, and
zeroing them breaks the migration.

Besides, in newer QEMU the content of those pages is fully managed by
QEMU, so zeroing them is undesirable even when writing the MSRs from the
guest side.

To support this new scheme, introduce a new capability,
KVM_CAP_HYPERV_SYNIC2, which, when enabled, makes sure that the synic
pages aren't zeroed out in KVM.

dcda9b0471 mm, tree wide: replace __GFP_REPEAT by __GFP_RETRY_MAYFAIL with more useful semantic 
__GFP_REPEAT was designed to allow retry-but-eventually-fail semantic to
the page allocator.  This has been true but only for allocations
requests larger than PAGE_ALLOC_COSTLY_ORDER.  It has been always
ignored for smaller sizes.  This is a bit unfortunate because there is
no way to express the same semantic for those requests and they are
considered too important to fail so they might end up looping in the
page allocator for ever, similarly to GFP_NOFAIL requests.

Now that the whole tree has been cleaned up and accidental or misled
usage of __GFP_REPEAT flag has been removed for !costly requests we can
give the original flag a better name and more importantly a more useful
semantic.  Let's rename it to __GFP_RETRY_MAYFAIL which tells the user
that the allocator would try really hard but there is no promise of a
success.  This will work independent of the order and overrides the
default allocator behavior.  Page allocator users have several levels of
guarantee vs.  cost options (take GFP_KERNEL as an example)

 - GFP_KERNEL & ~__GFP_RECLAIM - optimistic allocation without _any_
   attempt to free memory at all. The most light weight mode which even
   doesn't kick the background reclaim. Should be used carefully because
   it might deplete the memory and the next user might hit the more
   aggressive reclaim

 - GFP_KERNEL & ~__GFP_DIRECT_RECLAIM (or GFP_NOWAIT)- optimistic
   allocation without any attempt to free memory from the current
   context but can wake kswapd to reclaim memory if the zone is below
   the low watermark. Can be used from either atomic contexts or when
   the request is a performance optimization and there is another
   fallback for a slow path.

 - (GFP_KERNEL|__GFP_HIGH) & ~__GFP_DIRECT_RECLAIM (aka GFP_ATOMIC) -
   non sleeping allocation with an expensive fallback so it can access
   some portion of memory reserves. Usually used from interrupt/bh
   context with an expensive slow path fallback.

 - GFP_KERNEL - both background and direct reclaim are allowed and the
   _default_ page allocator behavior is used. That means that !costly
   allocation requests are basically nofail but there is no guarantee of
   that behavior so failures have to be checked properly by callers
   (e.g. OOM killer victim is allowed to fail currently).

 - GFP_KERNEL | __GFP_NORETRY - overrides the default allocator behavior
   and all allocation requests fail early rather than cause disruptive
   reclaim (one round of reclaim in this implementation). The OOM killer
   is not invoked.

 - GFP_KERNEL | __GFP_RETRY_MAYFAIL - overrides the default allocator
   behavior and all allocation requests try really hard. The request
   will fail if the reclaim cannot make any progress. The OOM killer
   won't be triggered.

 - GFP_KERNEL | __GFP_NOFAIL - overrides the default allocator behavior
   and all allocation requests will loop endlessly until they succeed.
   This might be really dangerous especially for larger orders.

Existing users of __GFP_REPEAT are changed to __GFP_RETRY_MAYFAIL
because they already had their semantic.  No new users are added.
__alloc_pages_slowpath is changed to bail out for __GFP_RETRY_MAYFAIL if
there is no progress and we have already passed the OOM point.

This means that all the reclaim opportunities have been exhausted except
the most disruptive one (the OOM killer) and a user defined fallback
behavior is more sensible than keep retrying in the page allocator.

e41d58185f fault-inject: support systematic fault injection 
Add /proc/self/task/<current-tid>/fail-nth file that allows failing
0-th, 1-st, 2-nd and so on calls systematically.
Excerpt from the added documentation:

 "Write to this file of integer N makes N-th call in the current task
  fail (N is 0-based). Read from this file returns a single char 'Y' or
  'N' that says if the fault setup with a previous write to this file
  was injected or not, and disables the fault if it wasn't yet injected.
  Note that this file enables all types of faults (slab, futex, etc).
  This setting takes precedence over all other generic settings like
  probability, interval, times, etc. But per-capability settings (e.g.
  fail_futex/ignore-private) take precedence over it. This feature is
  intended for systematic testing of faults in a single system call. See
  an example below"

Why add a new setting:
1. Existing settings are global rather than per-task.
   So parallel testing is not possible.
2. attr->interval is close but it depends on attr->count
   which is non reset to 0, so interval does not work as expected.
3. Trying to model this with existing settings requires manipulations
   of all of probability, interval, times, space, task-filter and
   unexposed count and per-task make-it-fail files.
4. Existing settings are per-failure-type, and the set of failure
   types is potentially expanding.
5. make-it-fail can't be changed by unprivileged user and aggressive
   stress testing better be done from an unprivileged user.
   Similarly, this would require opening the debugfs files to the
   unprivileged user, as he would need to reopen at least times file
   (not possible to pre-open before dropping privs).

The proposed interface solves all of the above (see the example).

We want to integrate this into syzkaller fuzzer.  A prototype has found
10 bugs in kernel in first day of usage:

  https://groups.google.com/forum/#!searchin/syzkaller/%22FAULT_INJECTION%22%7Csort:relevance

I've made the current interface work with all types of our sandboxes.
For setuid the secret sauce was prctl(PR_SET_DUMPABLE, 1, 0, 0, 0) to
make /proc entries non-root owned.  So I am fine with the current
version of the code.

77493f04b7 procfs: fdinfo: extend information about epoll target files 
Since it is possbile to have same number in tfd field (say file added,
closed, then nother file dup'ed to same number and added back) it is
imposible to distinguish such target files solely by their numbers.

Strictly speaking regular applications don't need to recognize these
targets at all but for checkpoint/restore sake we need to collect
targets to be able to push them back on restore stage in a proper order.

Thus lets add file position, inode and device number where this target
lays.  This three fields can be used as a primary key for sorting, and
together with kcmp help CRIU can find out an exact file target (from the
whole set of processes being checkpointed).

d09b646882 mm: document highmem_is_dirtyable sysctl 
It seems that there are still people using 32b kernels which a lot of
memory and the IO tend to suck a lot for them by default.  Mostly
because writers are throttled too when the lowmem is used.  We have
highmem_is_dirtyable to work around that issue but it seems we never
bothered to document it.  Let's do it now, finally.

9f123ab544 mm, memory_hotplug: support movable_node for hotpluggable nodes 
movable_node kernel parameter allows making hotpluggable NUMA nodes to
put all the hotplugable memory into movable zone which allows more or
less reliable memory hotremove.  At least this is the case for the NUMA
nodes present during the boot (see find_zone_movable_pfns_for_nodes).

This is not the case for the memory hotplug, though.

	echo online > /sys/devices/system/memory/memoryXYZ/state

will default to a kernel zone (usually ZONE_NORMAL) unless the
particular memblock is already in the movable zone range which is not
the case normally when onlining the memory from the udev rule context
for a freshly hotadded NUMA node.  The only option currently is to have
a special udev rule to echo online_movable to all memblocks belonging to
such a node which is rather clumsy.  Not to mention this is inconsistent
as well because what ended up in the movable zone during the boot will
end up in a kernel zone after hotremove & hotadd without special care.

It would be nice to reuse memblock_is_hotpluggable but the runtime
hotplug doesn't have that information available because the boot and
hotplug paths are not shared and it would be really non trivial to make
them use the same code path because the runtime hotplug doesn't play
with the memblock allocator at all.

Teach move_pfn_range that MMOP_ONLINE_KEEP can use the movable zone if
movable_node is enabled and the range doesn't overlap with the existing
normal zone.  This should provide a reasonable default onlining
strategy.

Strictly speaking the semantic is not identical with the boot time
initialization because find_zone_movable_pfns_for_nodes covers only the
hotplugable range as described by the BIOS/FW.  From my experience this
is usually a full node though (except for Node0 which is special and
never goes away completely).  If this turns out to be a problem in the
real life we can tweak the code to store hotplug flag into memblocks but
let's keep this simple now.

b6bb981149 mm, vmpressure: pass-through notification support 
By default, vmpressure events are not pass-through, i.e.  they propagate
up through the memcg hierarchy until an event notifier is found for any
threshold level.

This presents a difficulty when a thread waiting on a read(2) for a
vmpressure event cannot distinguish between local memory pressure and
memory pressure in a descendant memcg, especially when that thread may
not control the memcg hierarchy.

Consider a user-controlled child memcg with a smaller limit than a
top-level memcg controlled by the "Activity Manager" specified in
Documentation/cgroup-v1/memory.txt.  It may register for memory pressure
notification for descendant memcgs to make a policy decision: oom kill a
low priority job, increase the limit, decrease other limits, etc.  If it
registers for memory pressure notification on the top-level memcg, it
currently cannot distinguish between memory pressure in its own memcg or
a descendant memcg, which is user-controlled.

Conversely, if a user registers for memory pressure notification on
their own descendant memcg, the Activity Manager does not receive any
pressure notification for that child memcg hierarchy.  Vmpressure events
are not received for ancestor memcgs if the memcg experiencing pressure
have notifiers registered, perhaps outside the knowledge of the thread
waiting on read(2) at the top level.

Both of these are consequences of vmpressure notification not being
pass-through.

This implements a pass-through behavior for vmpressure events.  When
writing to control.event_control, vmpressure event handlers may
optionally specify a mode.  There are two new modes:

 - "hierarchy": always propagate memory pressure events up the hierarchy
   regardless if descendant memcgs have their own notifiers registered,
   and

 - "local": only receive notifications when the memcg for which the
   event is registered experiences memory pressure.

Of course, processes may register for one notification of "low,local",
for example, and another for "low".

If no mode is specified, the current behavior is maintained for
backwards compatibility.

See the change to Documentation/cgroup-v1/memory.txt for full
specification.

5cdd4c0468 for-f2fs-4.13 
In this round, we've added new features such as disk quota and statx, and
 modified internal bio management flow to merge more IOs depending on block
 types. We've also made internal threads freezeable for Android battery life.
 In addition to them, there are some patches to avoid lock contention as well
 as a couple of deadlock conditions.
 
 = Enhancement
 - support usrquota, grpquota, and statx
 - manage DATA/NODE typed bios separately to serialize more IOs
 - modify f2fs_lock_op/wio_mutex to avoid lock contention
 - prevent lock contention in migratepage
 
 = Bug fix
 - miss to load written inode flag
 - fix worst case victim selection in GC
 - freezeable GC and discard threads for Android battery life
 - sanitize f2fs metadata to deal with security hole
 - clean up sysfs-related code and docs

7cee9384cb Fix up over-eager 'wait_queue_t' renaming 
Commit ac6424b981 ("sched/wait: Rename wait_queue_t =>
wait_queue_entry_t") had scripted the renaming incorrectly, and didn't
actually check that the 'wait_queue_t' was a full token.

As a result, it also triggered on 'wait_queue_token', and renamed that
to 'wait_queue_entry_token' entry in the autofs4 packet structure
definition too.  That was entirely incorrect, and not intended.

The end result built fine when building just the kernel - because
everything had been renamed consistently there - but caused problems in
user space because the "struct autofs_packet_missing" type is exported
as part of the uapi.

This scripts it all back again:

    git grep -lw wait_queue_entry_token |
        xargs sed -i 's/wait_queue_entry_token/wait_queue_token/g'

and checks the end result.

0abd675e97 f2fs: support plain user/group quota 
This patch adds to support plain user/group quota.

Change Note by Jaegeuk Kim.

- Use f2fs page cache for quota files in order to consider garbage collection.
  so, quota files are not tolerable for sudden power-cuts, so user needs to do
  quotacheck.

- setattr() calls dquot_transfer which will transfer inode->i_blocks.
  We can't reclaim that during f2fs_evict_inode(). So, we need to count
  node blocks as well in order to match i_blocks with dquot's space.

  Note that, Chao wrote a patch to count inode->i_blocks without inode block.
  (f2fs: don't count inode block in in-memory inode.i_blocks)

- in f2fs_remount, we need to make RW in prior to dquot_resume.

- handle fault_injection case during f2fs_quota_off_umount

- TODO: Project quota

Pull Writeback error handling updates from Jeff Layton:
 "This pile represents the bulk of the writeback error handling fixes
  that I have for this cycle. Some of the earlier patches in this pile
  may look trivial but they are prerequisites for later patches in the
  series.

  The aim of this set is to improve how we track and report writeback
  errors to userland. Most applications that care about data integrity
  will periodically call fsync/fdatasync/msync to ensure that their
  writes have made it to the backing store.

  For a very long time, we have tracked writeback errors using two flags
  in the address_space: AS_EIO and AS_ENOSPC. Those flags are set when a
  writeback error occurs (via mapping_set_error) and are cleared as a
  side-effect of filemap_check_errors (as you noted yesterday). This
  model really sucks for userland.

  Only the first task to call fsync (or msync or fdatasync) will see the
  error. Any subsequent task calling fsync on a file will get back 0
  (unless another writeback error occurs in the interim). If I have
  several tasks writing to a file and calling fsync to ensure that their
  writes got stored, then I need to have them coordinate with one
  another. That's difficult enough, but in a world of containerized
  setups that coordination may even not be possible.

  But wait...it gets worse!

  The calls to filemap_check_errors can be buried pretty far down in the
  call stack, and there are internal callers of filemap_write_and_wait
  and the like that also end up clearing those errors. Many of those
  callers ignore the error return from that function or return it to
  userland at nonsensical times (e.g. truncate() or stat()). If I get
  back -EIO on a truncate, there is no reason to think that it was
  because some previous writeback failed, and a subsequent fsync() will
  (incorrectly) return 0.

  This pile aims to do three things:

   1) ensure that when a writeback error occurs that that error will be
      reported to userland on a subsequent fsync/fdatasync/msync call,
      regardless of what internal callers are doing

   2) report writeback errors on all file descriptions that were open at
      the time that the error occurred. This is a user-visible change,
      but I think most applications are written to assume this behavior
      anyway. Those that aren't are unlikely to be hurt by it.

   3) document what filesystems should do when there is a writeback
      error. Today, there is very little consistency between them, and a
      lot of cargo-cult copying. We need to make it very clear what
      filesystems should do in this situation.

  To achieve this, the set adds a new data type (errseq_t) and then
  builds new writeback error tracking infrastructure around that. Once
  all of that is in place, we change the filesystems to use the new
  infrastructure for reporting wb errors to userland.

  Note that this is just the initial foray into cleaning up this mess.
  There is a lot of work remaining here:

   1) convert the rest of the filesystems in a similar fashion. Once the
      initial set is in, then I think most other fs' will be fairly
      simple to convert. Hopefully most of those can in via individual
      filesystem trees.

   2) convert internal waiters on writeback to use errseq_t for
      detecting errors instead of relying on the AS_* flags. I have some
      draft patches for this for ext4, but they are not quite ready for
      prime time yet.

  This was a discussion topic this year at LSF/MM too. If you're
  interested in the gory details, LWN has some good articles about this:

98ced886dd Kbuild thin archives updates for v4.13 
Thin archives migration by Nicholas Piggin.
 
 THIN_ARCHIVES has been available for a while as an optional feature
 only for PowerPC architecture, but we do not need two different
 intermediate-artifact schemes.
 
 Using thin archives instead of conventional incremental linking has
 various advantages:
  - save disk space for builds
  - speed-up building a little
  - fix some link issues (for example, allyesconfig on ARM) due to
    more flexibility for the final linking
  - work better with dead code elimination we are planning
 
 As discussed before, this migration has been done unconditionally
 so that any problems caused by this will show up with "git bisect".
 
 With testing with 0-day and linux-next, some architectures actually
 showed up problems, but they were trivial and all fixed now.

c7d28eca1d This is the bulk of GPIO changes for the v4.13 series: 
Core:
 - Export add/remove for lookup tables so that modules can export GPIO
   descriptor tables.
 - Handle GPIO sleep states: it is now possible to flag that a GPIO line
   may loose its state during suspend/resume of the system to save
   power. This is used in the Wolfson Micro Arizona driver.
 - ACPI-based GPIO was tightened up a lot around the edges.
 - Use bitmap_fill() to speed up a loop.
 
 New drivers:
 - Exar XRA1403 SPI-based GPIO.
 - MVEBU driver now supports Armada 7K and 8K.
 - LP87565 PMIC GPIO.
 - Renesas R-CAR R8A7743 (RZ/G1M).
 - The new IOT2040 8250 serial/GPIO also comes in through this
   changeset.
 
 Substantial driver changes:
 - Seriously fix the Exar 8250 GPIO portions to work.
 - The MCP23S08 was moved out to a pin control driver.
 - Convert MEVEBU to use regmap for register access.
 - Drop Vulcan support from the Broadcom driver.
 - Serious cleanup and improvement of the mockup driver, giving us a
   better test coverage.
 
 Misc:
 - Lots of janitorial clean up.
 - A bunch of documentation fixes.

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v4.13 series.

  Some administrativa:

  I have a slew of 8250 serial patches and the new IOT2040 serial+GPIO
  driver coming in through this tree, along with a whole bunch of Exar
  8250 fixes. These are ACKed by Greg and also hit drivers/platform/*
  where they are ACKed by Andy Shevchenko.

  Speaking about drivers/platform/* there is also a bunch of ACPI stuff
  coming through that route, again ACKed by Andy.

  The MCP23S08 changes are coming in here as well. You already have the
  commits in your tree, so this is just a result of sharing an immutable
  branch between pin control and GPIO.

  Core:
   - Export add/remove for lookup tables so that modules can export GPIO
     descriptor tables.
   - Handle GPIO sleep states: it is now possible to flag that a GPIO
     line may loose its state during suspend/resume of the system to
     save power. This is used in the Wolfson Micro Arizona driver.
   - ACPI-based GPIO was tightened up a lot around the edges.

daeb433e42 f2fs: introduce reserved_blocks in sysfs 
In this patch, we add a new sysfs interface, with it, we can control
number of reserved blocks in system which could not be used by user,
it enable f2fs to let user to configure for adjusting over-provision
ratio dynamically instead of changing it by mkfs.

So we can expect it will help to reserve more free space for relieving
GC in both filesystem and flash device.

697e5a47aa rtc: add generic nvmem support 
Many RTCs have an on board non volatile storage. It can be battery backed
RAM or an EEPROM. Use the nvmem subsystem to export it to both userspace
and in-kernel consumers.

This stays compatible with the previous (non documented) ABI that was using
/sys/class/rtc/rtcx/device/nvram to export that memory. But will warn about
the deprecation.

f70029bbaa mm, memory_hotplug: drop CONFIG_MOVABLE_NODE 
Commit 20b2f52b73 ("numa: add CONFIG_MOVABLE_NODE for
movable-dedicated node") has introduced CONFIG_MOVABLE_NODE without a
good explanation on why it is actually useful.

It makes a lot of sense to make movable node semantic opt in but we
already have that because the feature has to be explicitly enabled on
the kernel command line.  A config option on top only makes the
configuration space larger without a good reason.  It also adds an
additional ifdefery that pollutes the code.

Just drop the config option and make it de-facto always enabled.  This
shouldn't introduce any change to the semantic.

94f4a1618b mm: kmemleak: treat vm_struct as alternative reference to vmalloc'ed objects 
Kmemleak requires that vmalloc'ed objects have a minimum reference count
of 2: one in the corresponding vm_struct object and the other owned by
the vmalloc() caller.  There are cases, however, where the original
vmalloc() returned pointer is lost and, instead, a pointer to vm_struct
is stored (see free_thread_stack()).  Kmemleak currently reports such
objects as leaks.

This patch adds support for treating any surplus references to an object
as additional references to a specified object.  It introduces the
kmemleak_vmalloc() API function which takes a vm_struct pointer and sets
its surplus reference passing to the actual vmalloc() returned pointer.
The __vmalloc_node_range() calling site has been modified accordingly.

2c653d0ee2 ksm: introduce ksm_max_page_sharing per page deduplication limit 
Without a max deduplication limit for each KSM page, the list of the
rmap_items associated to each stable_node can grow infinitely large.

During the rmap walk each entry can take up to ~10usec to process
because of IPIs for the TLB flushing (both for the primary MMU and the
secondary MMUs with the MMU notifier).  With only 16GB of address space
shared in the same KSM page, that would amount to dozens of seconds of
kernel runtime.

A ~256 max deduplication factor will reduce the latencies of the rmap
walks on KSM pages to order of a few msec.  Just doing the
cond_resched() during the rmap walks is not enough, the list size must
have a limit too, otherwise the caller could get blocked in (schedule
friendly) kernel computations for seconds, unexpectedly.

There's room for optimization to significantly reduce the IPI delivery
cost during the page_referenced(), but at least for page_migration in
the KSM case (used by hard NUMA bindings, compaction and NUMA balancing)
it may be inevitable to send lots of IPIs if each rmap_item->mm is
active on a different CPU and there are lots of CPUs.  Even if we ignore
the IPI delivery cost, we've still to walk the whole KSM rmap list, so
we can't allow millions or billions (ulimited) number of entries in the
KSM stable_node rmap_item lists.

The limit is enforced efficiently by adding a second dimension to the
stable rbtree.  So there are three types of stable_nodes: the regular
ones (identical as before, living in the first flat dimension of the
stable rbtree), the "chains" and the "dups".

Every "chain" and all "dups" linked into a "chain" enforce the invariant
that they represent the same write protected memory content, even if
each "dup" will be pointed by a different KSM page copy of that content.
This way the stable rbtree lookup computational complexity is unaffected
if compared to an unlimited max_sharing_limit.  It is still enforced
that there cannot be KSM page content duplicates in the stable rbtree
itself.

Adding the second dimension to the stable rbtree only after the
max_page_sharing limit hits, provides for a zero memory footprint
increase on 64bit archs.  The memory overhead of the per-KSM page
stable_tree and per virtual mapping rmap_item is unchanged.  Only after
the max_page_sharing limit hits, we need to allocate a stable_tree
"chain" and rb_replace() the "regular" stable_node with the newly
allocated stable_node "chain".  After that we simply add the "regular"
stable_node to the chain as a stable_node "dup" by linking hlist_dup in
the stable_node_chain->hlist.  This way the "regular" (flat) stable_node
is converted to a stable_node "dup" living in the second dimension of
the stable rbtree.

During stable rbtree lookups the stable_node "chain" is identified as
stable_node->rmap_hlist_len == STABLE_NODE_CHAIN (aka
is_stable_node_chain()).

When dropping stable_nodes, the stable_node "dup" is identified as
stable_node->head == STABLE_NODE_DUP_HEAD (aka is_stable_node_dup()).

The STABLE_NODE_DUP_HEAD must be an unique valid pointer never used
elsewhere in any stable_node->head/node to avoid a clashes with the
stable_node->node.rb_parent_color pointer, and different from
&migrate_nodes.  So the second field of &migrate_nodes is picked and
verified as always safe with a BUILD_BUG_ON in case the list_head
implementation changes in the future.

The STABLE_NODE_DUP is picked as a random negative value in
stable_node->rmap_hlist_len.  rmap_hlist_len cannot become negative when
it's a "regular" stable_node or a stable_node "dup".

The stable_node_chain->nid is irrelevant.  The stable_node_chain->kpfn
is aliased in a union with a time field used to rate limit the
stable_node_chain->hlist prunes.

The garbage collection of the stable_node_chain happens lazily during
stable rbtree lookups (as for all other kind of stable_nodes), or while
disabling KSM with "echo 2 >/sys/kernel/mm/ksm/run" while collecting the
entire stable rbtree.

While the "regular" stable_nodes and the stable_node "dups" must wait
for their underlying tree_page to be freed before they can be freed
themselves, the stable_node "chains" can be freed immediately if the
stable_node->hlist turns empty.  This is because the "chains" are never
pointed by any page->mapping and they're effectively stable rbtree KSM
self contained metadata.

7660a6fddc mm: allow slab_nomerge to be set at build time 
Some hardened environments want to build kernels with slab_nomerge
already set (so that they do not depend on remembering to set the kernel
command line option).  This is desired to reduce the risk of kernel heap
overflows being able to overwrite objects from merged caches and changes
the requirements for cache layout control, increasing the difficulty of
these attacks.  By keeping caches unmerged, these kinds of exploits can
usually only damage objects in the same cache (though the risk to
metadata exploitation is unchanged).

3a564bb3a8 - Add the ability to use select or poll /dev/mapper/control to wait for 
events from multiple DM devices.
 
 - Convert DM's printk macros over to using pr_<level> macros.
 
 - Add a big-endian variant of plain64 IV to dm-crypt.
 
 - Add support for zoned (aka SMR) devices to DM core.  DM kcopyd was
   also improved to provide a sequential write feature needed by zoned
   devices.
 
 - Introduce DM zoned target that provides support for host-managed zoned
   devices, the result dm-zoned device acts as a drive-managed interface
   to the underlying host-managed device.
 
 - A DM raid fix to avoid using BUG() for error handling.

ac7b75966c This is the big bulk of pin control changes for the v4.13 series: 
Core:
 
 - The documentation is moved over to RST.
 - We now have agreed bindings for enabling input and output
   buffers without actually enabling input and/or output on a
   pin. We are chiseling out some details of pin control
   electronics.
 
 New drivers:
 
 - ZTE ZX
 - Renesas RZA1
 - MIPS Ingenic JZ47xx: also switch over existing drivers in the
   tree to use this pin controller and consolidate earlier
   spread out code.
 - Microschip MCP23S08: this driver is migrated from the GPIO
   subsystem and totally rewritten to use proper pin control.
   All users are switched over.
 
 New subdrivers:
 
 - Renesas R8A7743 and R8A7745.
 - Allwinner Sunxi A83T R_PIO.
 - Marvell MVEBU Armada CP110 and AP806.
 - Intel Cannon Lake PCH.
 - Qualcomm IPQ8074.
 
 Notable improvements:
 
 - IRQ support on the Marvell MVEBU Armada 37xx.
 - Meson driver supports HDMI CEC, AO, I2S, SPDIF and PWM.
 - Rockchip driver now supports iomux-route switching for
   RK3228, RK3328 and RK3399.
 - Rockchip A10 and A20 are merged into a single driver.
 - STM32 has improved GPIO support.
 - Samsung Exynos drivers are split per ARMv7 and ARMv8.
 - Marvell MVEBU is converted to use regmap for register
   access.
 
 Maintenance:
 
 - Several Renesas SH-PFC refactorings and updates.
 - Serious code size cut for Mediatek MT7623.
 - Misc janitorial and MAINTAINERS fixes.

 "This time we're removing more than adding:

  Removed drivers:

    leds-versatile:
      - all users of the Versatile LED driver are deleted and replaced

    leds-sead3:
      - SEAD3 is using the generic leds-syscon & regmap based
        register-bit-led driver

  LED class drivers improvements:

    ledtrig-gpio:
      - use threaded IRQ, which both simplifies the code because we can
        drop the workqueue indirection, and it enables using the trigger
        for GPIOs that work with threaded IRQs themselves
      - refresh LED state after GPIO change since the new GPIO may have
        a different state than the old one

920f2ecdf6 sound updates for 4.13-rc1 
This development cycle resulted in a fair amount of changes in both
 core and driver sides.  The most significant change in ALSA core is
 about PCM.  Also the support of of-graph card and the new DAPM widget
 for DSP are noteworthy changes in ASoC core.  And there're lots of
 small changes splat over the tree, as you can see in diffstat.
 
 Below are a few highlights:
 
 ALSA core:
 - Removal of set_fs() hackery from PCM core stuff, and the code
   reorganization / optimization thereafter
 - Improved support of PCM ack ops, and a new ABI for improved
   control/status mmap handling
 - Lots of constifications in various codes
 
 ASoC core:
 - The support of of-graph card, which may work as a better generic
   device for a replacement of simple-card
 - New widget types intended mainly for use with DSPs
 
 ASoC drivers:
 - New drivers for Allwinner V3s SoCs
 - Ensonic ES8316 codec support
 - More Intel SKL and KBL works
 - More device support for Intel SST Atom (mostly for cheap tablets and
   2-in-1 devices)
 - Support for Rockchip PDM controllers
 - Support for STM32 I2S and S/PDIF controllers
 - Support for ZTE AUD96P22 codecs
 
 HD-audio:
 - Support of new Realtek codecs (ALC215/ALC285/ALC289), more quirks
   for HP and Dell machines
 - A few more fixes for i915 component binding
 
 Note that of-graph change may bring the conflicts with a later pull
 request of devicetree, as currently found in linux-next.

Merge tag 'gcc-plugins-v4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull GCC plugin updates from Kees Cook:
 "The big part is the randstruct plugin infrastructure.

  This is the first of two expected pull requests for randstruct since
  there are dependencies in other trees that would be easier to merge
  once those have landed. Notably, the IPC allocation refactoring in
  -mm, and many trivial merge conflicts across several trees when
  applying the __randomize_layout annotation.

  As a result, it seemed like I should send this now since it is
  relatively self-contained, and once the rest of the trees have landed,
  send the annotation patches. I'm expecting the final phase of
  randstruct (automatic struct selection) will land for v4.14, but if
  its other tree dependencies actually make it for v4.13, I can send
  that merge request too.

  Summary:

  - typo fix in Kconfig (Jean Delvare)

  - randstruct infrastructure"

e24dd9ee53 Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security 
Pull security layer updates from James Morris:

 - a major update for AppArmor. From JJ:

     * several bug fixes and cleanups

     * the patch to add symlink support to securityfs that was floated
       on the list earlier and the apparmorfs changes that make use of
       securityfs symlinks

     * it introduces the domain labeling base code that Ubuntu has been
       carrying for several years, with several cleanups applied. And it
       converts the current mediation over to using the domain labeling
       base, which brings domain stacking support with it. This finally
       will bring the base upstream code in line with Ubuntu and provide
       a base to upstream the new feature work that Ubuntu carries.

     * This does _not_ contain any of the newer apparmor mediation
       features/controls (mount, signals, network, keys, ...) that
       Ubuntu is currently carrying, all of which will be RFC'd on top
       of this.

 - Notable also is the Infiniband work in SELinux, and the new file:map
   permission. From Paul:

      "While we're down to 21 patches for v4.13 (it was 31 for v4.12),
       the diffstat jumps up tremendously with over 2k of line changes.

       Almost all of these changes are the SELinux/IB work done by
       Daniel Jurgens; some other noteworthy changes include a NFS v4.2
       labeling fix, a new file:map permission, and reporting of policy
       capabilities on policy load"

   There's also now genfscon labeling support for tracefs, which was
   lost in v4.1 with the separation from debugfs.

 - Smack incorporates a safer socket check in file_receive, and adds a
   cap_capable call in privilege check.

 - TPM as usual has a bunch of fixes and enhancements.

 - Multiple calls to security_add_hooks() can now be made for the same
   LSM, to allow LSMs to have hook declarations across multiple files.

 - IMA now supports different "ima_appraise=" modes (eg. log, fix) from
   the boot command line.

908a773325 dt-bindings: phy: dp83867: provide a workaround for incorrect RX_CTRL pin strap 
The data manual for DP83867IR/CR, SNLS484E[1], revised march 2017,
advises that strapping RX_DV/RX_CTRL pin in mode 1 and 2 is not
supported (see note below Table 5 (4-Level Strap Pins)).

It further advises that if a board has this pin strapped in mode 1 and
mode 2, then to ensure proper operation of the PHY, a software workaround
must be implemented.

Since it is not possible to detect in software if RX_DV/RX_CTRL pin is
incorrectly strapped, add a device-tree property for the board to
advertise this and allow corrective action in software.

Device-tree updates for arm64 platforms. For the first time I can
 remember, this is actually larger than the corresponding branch for
 32-bit platforms overall, though that has more individual changes.
 
 A significant portion this time is due to added machine support:
 
 - Initial support for the Realtek RTD1295 SoC, along with the Zidoo
   X9S set-top-box
 
 - Initial support for Actions Semi S900 and the Bubblegum-96
   single-board-cёmputer.
 
 - Rockchips support for the rk3399-Firefly single-board-computer
   gets added, this one stands out for being relatively fast,
   affordable and well₋supported, compared to many boards that
   only fall into one or two of the above categories.
 
 - Mediatek gains support for the mt6797 mobile-phone SoC platform
   and corresponding evaluation board.
 
 - Amlogic board support gets added for the NanoPi K2 and S905x
   LibreTech CC single-board computers and the R-Box Pro set-top-box
 
 - Allwinner board support gets added for the OrangePi Win,
   Orangepi Zero Plus 2, NanoPi NEO2 and Orange Pi Prime single
   board computers and the SoPine system-on-module.
 
 - Renesas board support for Salvator-XS and H3ULCB
   automotive development systems.
 
 - Socionext Uniphier board support for LD11-global and LD20-global,
   whatever those may be.
 
 - Broadcom adds support for the new Stingray communication processor
   in its iProc family, along with two reference boards.
 
 Other updates include:
 
 - For the hisicon platform, support for Hi3660-Hikey960 gets
   extended significantly.
 
 - Lots of smaller updates for Renesas, Amlogic, Rockchip, UniPhier,
   Broadcom, Allwinner, Hisilicon, Qualcomm, Marvell, and NXP.

e854711291 ARM: SoC driver updates 
- New SoC specific drivers
   - NVIDIA Tegra PM Domain support for newer SoCs (Tegra186 and later)
     based on the "BPMP" firmware
   - Clocksource and system controller drivers for the newly added
     Action Semi platforms (both arm and arm64).
 
 - Reset subsystem, merged through arm-soc by tradition:
   - New drivers for Altera Stratix10, TI Keystone and Cortina Gemini SoCs
   - Various subsystem-wide cleanups
 
 - Updates for existing SoC-specific drivers
   - TI GPMC (General Purpose Memory Controller)
   - Mediatek "scpsys" system controller support for MT6797
   - Broadcom "brcmstb_gisb" bus arbitrer
   - ARM SCPI firmware
   - Renesas "SYSC" system controller
 
 One more driver update was submitted for the Freescale/NXP DPAA
 data path acceleration that has previously been used on PowerPC
 chips. I ended up postponing the merge until some API questions
 for its unusual MMIO access are resolved.

1849f800fb ARM: Device-tree updates 
Device-tree continues to see lots of updates. The majority of patches
 here are smaller changes for new hardware on existing platforms, and
 there are a few larger changes worth pointing out.
 
 New machines:
 
 - The new Action Semi S500 platform is added along with initial
   support for the LeMaker Guitar board.
 
 - STM32 gains support for three new boards: stm32h743-disco,
   stm32f746-disco, and stm32f769-disco, along with new device
   support for the existing stm32f429 boards.
 
 - Renesas adds two new boards, the tiny GR-Peach based on RZ/A1H
   with 10MB on-chip SRAM, and the iWave G20D-Q7 System-on-Module
   plus board.
 
 - On Marvell "mvebu", we gain support for the Linksys WRT3200ACM
   wireless router.
 
 - For NXP i.MX, we gain support for the Gateworks Ventana GW5600
   and the Technexion Pico i.MX7D single-board computers.
 
 - The BeagleBone Blue is added for OMAP, it's the latest variation
   of the popular Beaglebone Black single-board computer.
 
 - The Allwinner based Lichee Pi Zero and NanoPi M1 Plus boards
   are added, these are the latest variations of a seemingly endless
   supply of similar single-board computers.
 
 Other updates:
 
 - Linus Walleij improves support for the "Faraday" based SoC platforms
   from various SoC makers (Moxart, Aspeed, Gemini)
 
 - The ARM Mali GPU is now describe on Rockchips SoCs
 
 - Mediatek MT7623 is extended significantly, making it much
   more useful.
 
 - Lots of individual updates on Renesas, OMAP, Rockchips, Broadcom,
   Allwinner, Qualcomm, iMX
 
 - For Amlogic, the clock support is extended a lot on meson8b.
 
 - We now build the devicetree file for the Raspberry Pi 3 on 32-bit
   ARM, in addition to the existing ARM64 support, to help users
   wanting to run a 32-bit system on it.

408c9861c6 Power management updates for v4.13-rc1 
- Rework suspend-to-idle to allow it to take wakeup events signaled
    by the EC into account on ACPI-based platforms in order to properly
    support power button wakeup from suspend-to-idle on recent Dell
    laptops (Rafael Wysocki).
 
    That includes the core suspend-to-idle code rework, support for
    the Low Power S0 _DSM interface, and support for the ACPI INT0002
    Virtual GPIO device from Hans de Goede (required for USB keyboard
    wakeup from suspend-to-idle to work on some machines).
 
  - Stop trying to export the current CPU frequency via /proc/cpuinfo
    on x86 as that is inaccurate and confusing (Len Brown).
 
  - Rework the way in which the current CPU frequency is exported by
    the kernel (over the cpufreq sysfs interface) on x86 systems with
    the APERF and MPERF registers by always using values read from
    these registers, when available, to compute the current frequency
    regardless of which cpufreq driver is in use (Len Brown).
 
  - Rework the PCI/ACPI device wakeup infrastructure to remove the
    questionable and artificial distinction between "devices that
    can wake up the system from sleep states" and "devices that can
    generate wakeup signals in the working state" from it, which
    allows the code to be simplified quite a bit (Rafael Wysocki).
 
  - Fix the wakeup IRQ framework by making it use SRCU instead of
    RCU which doesn't allow sleeping in the read-side critical
    sections, but which in turn is expected to be allowed by the
    IRQ bus locking infrastructure (Thomas Gleixner).
 
  - Modify some computations in the intel_pstate driver to avoid
    rounding errors resulting from them (Srinivas Pandruvada).
 
  - Reduce the overhead of the intel_pstate driver in the HWP
    (hardware-managed P-states) mode and when the "performance"
    P-state selection algorithm is in use by making it avoid
    registering scheduler callbacks in those cases (Len Brown).
 
  - Rework the energy_performance_preference sysfs knob in
    intel_pstate by changing the values that correspond to
    different symbolic hint names used by it (Len Brown).
 
  - Make it possible to use more than one cpuidle driver at the same
    time on ARM (Daniel Lezcano).
 
  - Make it possible to prevent the cpuidle menu governor from using
    the 0 state by disabling it via sysfs (Nicholas Piggin).
 
  - Add support for FFH (Fixed Functional Hardware) MWAIT in ACPI C1
    on AMD systems (Yazen Ghannam).
 
  - Make the CPPC cpufreq driver take the lowest nonlinear performance
    information into account (Prashanth Prakash).
 
  - Add support for hi3660 to the cpufreq-dt driver, fix the
    imx6q driver and clean up the sfi, exynos5440 and intel_pstate
    drivers (Colin Ian King, Krzysztof Kozlowski, Octavian Purdila,
    Rafael Wysocki, Tao Wang).
 
  - Fix a few minor issues in the generic power domains (genpd)
    framework and clean it up somewhat (Krzysztof Kozlowski,
    Mikko Perttunen, Viresh Kumar).
 
  - Fix a couple of minor issues in the operating performance points
    (OPP) framework and clean it up somewhat (Viresh Kumar).
 
  - Fix a CONFIG dependency in the hibernation core and clean it up
    slightly (Balbir Singh, Arvind Yadav, BaoJun Luo).
 
  - Add rk3228 support to the rockchip-io adaptive voltage scaling
    (AVS) driver (David Wu).
 
  - Fix an incorrect bit shift operation in the RAPL power capping
    driver (Adam Lessnau).
 
  - Add support for the EPP field in the HWP (hardware managed
    P-states) control register, HWP.EPP, to the x86_energy_perf_policy
    tool and update msr-index.h with HWP.EPP values (Len Brown).
 
  - Fix some minor issues in the turbostat tool (Len Brown).
 
  - Add support for AMD family 0x17 CPUs to the cpupower tool and fix
    a minor issue in it (Sherry Hurwitz).
 
  - Assorted cleanups, mostly related to the constification of some
    data structures (Arvind Yadav, Joe Perches, Kees Cook, Krzysztof
    Kozlowski).

Pull power management updates from Rafael Wysocki:
 "The big ticket items here are the rework of suspend-to-idle in order
  to add proper support for power button wakeup from it on recent Dell
  laptops and the rework of interfaces exporting the current CPU
  frequency on x86.

  In addition to that, support for a few new pieces of hardware is
  added, the PCI/ACPI device wakeup infrastructure is simplified
  significantly and the wakeup IRQ framework is fixed to unbreak the IRQ
  bus locking infrastructure.

  Also, there are some functional improvements for intel_pstate, tools
  updates and small fixes and cleanups all over.

9412812ef5 ovl: document copying layers restrictions with inodes index 
The inodes index feature introduces a behavior change - on mount,
upper root origin file handle is verified to match the lower root dir.
This implies that copied layers cannot be mounted with the inodes index
feature enabled, without explicitly removing the upper dir origin xattr
and the index dir.

The inodes index feature is required to support:
- Prevent breaking hardlinks on copy up
- NFS export support (upcoming)
- Overlayfs snapshots (POC)

b39de277b0 spi: Updates for v4.13 
There's only one big change in this release but it's a very big change,
 Geert Uytterhoeven has implemented support for SPI slave mode.  This
 feature has been on the cards since the subsystem was originally merged
 back in the mists of time so it's great that Geert stepped up and
 finally implemented it.
 
  - SPI slave support, together with wholesale renaming of SPI
    controllers from master to controller which went surprisingly
    smoothly.  This is already used with Renesas SoCs and support is in
    the works for i.MX too.
  - New drivers for Meson SPICC and ST STM32

 happens, if not, we can send a follow-up patch for it afterward.

Linus Torvalds
03ffbcdd78 Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 
Pull irq updates from Thomas Gleixner:
 "The irq department delivers:

   - Expand the generic infrastructure handling the irq migration on CPU
     hotplug and convert X86 over to it. (Thomas Gleixner)

     Aside of consolidating code this is a preparatory change for:

   - Finalizing the affinity management for multi-queue devices. The
     main change here is to shut down interrupts which are affine to a
     outgoing CPU and reenabling them when the CPU comes online again.
     That avoids moving interrupts pointlessly around and breaking and
     reestablishing affinities for no value. (Christoph Hellwig)

     Note: This contains also the BLOCK-MQ and NVME changes which depend
     on the rework of the irq core infrastructure. Jens acked them and
     agreed that they should go with the irq changes.

   - Consolidation of irq domain code (Marc Zyngier)

   - State tracking consolidation in the core code (Jeffy Chen)

   - Add debug infrastructure for hierarchical irq domains (Thomas
     Gleixner)

   - Infrastructure enhancement for managing generic interrupt chips via
     devmem (Bartosz Golaszewski)

   - Constification work all over the place (Tobias Klauser)

   - Two new interrupt controller drivers for MVEBU (Thomas Petazzoni)

   - The usual set of fixes, updates and enhancements all over the
     place"
