Highlights incluse:
Features:
- Removing the forced serialisation of open()/close() calls in NFSv4.x (x>0)
makes for a significant performance improvement in metadata intensive
workloads.
- Full support for the pNFS "flexible files" layout type
- Further RPC/RDMA client improvements from Chuck
Bugfixes:
- Stable fix: NFSv4.1 backchannel calls blocking operations with !TASK_RUNNING
- Stable fix: pnfs_generic_pg_init_read/write can be called with lseg == NULL
- Stable fix: Fix an Oopsable condition when nsm_mon_unmon is called as part
of the namespace cleanup,
- Stable fix: Ensure we reference the inode for return-on-close in delegreturn
- Use SO_REUSEPORT to ensure that NFSv3 TCP connections can rebind to the
same source address/port combination during a disconnect/reconnect event.
This is a requirement imposed by most NFSv3 server duplicate reply cache
implementations.
Optimisations:
- Ask for no NFSv4.1 delegations on OPEN if using O_DIRECT
Other:
- Add Anna Schumaker as co-maintainer for the NFS client

This one was driving me mad, with several lines of warnings during the
allmodconfig build for a single bogus pointer cast. The warning was so
verbose due to the indirect macro expansion explanation, and the whole
thing was just for a debug printout.
The bogus pointer-to-integer cast was pointless anyway, so just remove
it, and use '%p' to show the pointer.

The device indicates the result of a read/write operation by making the
status available on a subsequent request from the driver. This is not
ready immediately, though, so the driver is currently slamming the
device with hundreds of pointless requests before getting the expected
response. Add a two millisecond delay before each attempt. This is
approximately the behavior observed with version 4.2.7.1 of the Windows
driver.

The BDW audio firmware DSP manages the DMA and the DMA cannot be
stopped exactly at the end of the playback stream. This means
stale samples may be played at PCM stop unless the driver copies
silence to the subsequent periods.

Commit 1d10eb2f15 ("crypto: switch af_alg_make_sg() to iov_iter")
broke af_alg_make_sg() and skcipher_recvmsg() in the process of moving
them to the iov_iter interfaces. The 'npages' calculation in the formar
calculated the number of *bytes* in the pages, and in the latter case
the conversion didn't re-read the value of 'ctx->used' after waiting for
it to become non-zero.
This reverts to the original code for both these cases.

Pull live patching infrastructure from Jiri Kosina:
"Let me provide a bit of history first, before describing what is in
this pile.
Originally, there was kSplice as a standalone project that implemented
stop_machine()-based patching for the linux kernel. This project got
later acquired, and the current owner is providing live patching as a
proprietary service, without any intentions to have their
implementation merged.
Then, due to rising user/customer demand, both Red Hat and SUSE
started working on their own implementation (not knowing about each
other), and announced first versions roughly at the same time [1] [2].
The principle difference between the two solutions is how they are
making sure that the patching is performed in a consistent way when it
comes to different execution threads with respect to the semantic
nature of the change that is being introduced.
In a nutshell, kPatch is issuing stop_machine(), then looking at
stacks of all existing processess, and if it decides that the system
is in a state that can be patched safely, it proceeds insterting code
redirection machinery to the patched functions.
On the other hand, kGraft provides a per-thread consistency during one
single pass of a process through the kernel and performs a lazy
contignuous migration of threads from "unpatched" universe to the
"patched" one at safe checkpoints.
If interested in a more detailed discussion about the consistency
models and its possible combinations, please see the thread that
evolved around [3].
It pretty quickly became obvious to the interested parties that it's
absolutely impractical in this case to have several isolated solutions
for one task to co-exist in the kernel. During a dedicated Live
Kernel Patching track at LPC in Dusseldorf, all the interested parties
sat together and came up with a joint aproach that would work for both
distro vendors. Steven Rostedt took notes [4] from this meeting.
And the foundation for that aproach is what's present in this pull
request.
It provides a basic infrastructure for function "live patching" (i.e.
code redirection), including API for kernel modules containing the
actual patches, and API/ABI for userspace to be able to operate on the
patches (look up what patches are applied, enable/disable them, etc).
It's relatively simple and minimalistic, as it's making use of
existing kernel infrastructure (namely ftrace) as much as possible.
It's also self-contained, in a sense that it doesn't hook itself in
any other kernel subsystem (it doesn't even touch any other code).
It's now implemented for x86 only as a reference architecture, but
support for powerpc, s390 and arm is already in the works (adding
arch-specific support basically boils down to teaching ftrace about
regs-saving).
Once this common infrastructure gets merged, both Red Hat and SUSE
have agreed to immediately start porting their current solutions on
top of this, abandoning their out-of-tree code. The plan basically is
that each patch will be marked by flag(s) that would indicate which
consistency model it is willing to use (again, the details have been
sketched out already in the thread at [3]).
Before this happens, the current codebase can be used to patch a large
group of secruity/stability problems the patches for which are not too
complex (in a sense that they don't introduce non-trivial change of
function's return value semantics, they don't change layout of data
structures, etc) -- this corresponds to LEAVE_FUNCTION &&
SWITCH_FUNCTION semantics described at [3].

Commit 84683a7e08 ("sata_dwc_460ex: enable COMPILE_TEST for the
driver") enabled this driver for non-ppc460-ex platforms, but it was
then disabled for ARM and ARM64 by commit 2de5a9c004 ("sata_dwc_460ex:
disable compilation on ARM and ARM64") because it's too noisy and
broken.
This disabled is entirely, because it's too noisy on x86-64 too, and
there's no point in disabling architectures one by one. At a minimum,
the code isn't 64-bit clean, and even on 32-bit it is questionable
whether it makes sense.

Merge misc updates from Andrew Morton:
"Bite-sized chunks this time, to avoid the MTA ratelimiting woes.
- fs/notify updates
- ocfs2
- some of MM"
That laconic "some MM" is mainly the removal of remap_file_pages(),
which is a big simplification of the VM, and which gets rid of a *lot*
of random cruft and special cases because we no longer support the
non-linear mappings that it used.
From a user interface perspective, nothing has changed, because the
remap_file_pages() syscall still exists, it's just done by emulating the
old behavior by creating a lot of individual small mappings instead of
one non-linear one.
The emulation is slower than the old "native" non-linear mappings, but
nobody really uses or cares about remap_file_pages(), and simplifying
the VM is a big advantage.

cpufreq driver, a new devfreq driver for Tegra Activity Monitor, a new
devfreq class for providing its governors with raw utilization data
and a new ACPI driver for AMD SoCs.
Still, the majority of changes here are reworks of existing code to
make it more straightforward or to prepare it for implementing new
features on top of it. The primary example is the rework of ACPI
resources handling from Jiang Liu, Thomas Gleixner and Lv Zheng with
support for IOAPIC hotplug implemented on top of it, but there is
quite a number of changes of this kind in the cpufreq core, ACPICA,
ACPI EC driver, ACPI processor driver and the generic power domains

mem_cgroup->memcg_slab_caches is a list of kmem caches corresponding to
the given cgroup. Currently, it is only used on css free in order to
destroy all caches corresponding to the memory cgroup being freed. The
list is protected by memcg_slab_mutex. The mutex is also used to protect
kmem_cache->memcg_params->memcg_caches arrays and synchronizes
kmem_cache_destroy vs memcg_unregister_all_caches.
However, we can perfectly get on without these two. To destroy all caches
corresponding to a memory cgroup, we can walk over the global list of kmem
caches, slab_caches, and we can do all the synchronization stuff using the
slab_mutex instead of the memcg_slab_mutex. This patch therefore gets rid
of the memcg_slab_caches and memcg_slab_mutex.
Apart from this nice cleanup, it also:
- assures that rcu_barrier() is called once at max when a root cache is
destroyed or a memory cgroup is freed, no matter how many caches have
SLAB_DESTROY_BY_RCU flag set;
- fixes the race between kmem_cache_destroy and kmem_cache_create that
exists, because memcg_cleanup_cache_params, which is called from
kmem_cache_destroy after checking that kmem_cache->refcount=0,
releases the slab_mutex, which gives kmem_cache_create a chance to
make an alias to a cache doomed to be destroyed.

Instead of passing the name of the memory cgroup which the cache is
created for in the memcg_name_argument, let's obtain it immediately in
memcg_create_kmem_cache.

They are simple wrappers around memcg_{charge,uncharge}_kmem, so let's
zap them and call these functions directly.

If the freeing page and its buddy page are not at the same zone, the
current holding zone->lock for the freeing page cann't prevent buddy page
getting allocated, this could trigger VM_BUG_ON_PAGE in page_is_buddy() at
a very tiny chance, such as:
cpu 0: cpu 1:
hold zone_1 lock
check page and it buddy
PageBuddy(buddy) is true hold zone_2 lock
page_order(buddy) == order is true alloc buddy
trigger VM_BUG_ON_PAGE(page_count(buddy) != 0)
zone_1->lock prevents the freeing page getting allocated
zone_2->lock prevents the buddy page getting allocated
they are not the same zone->lock.
If we can't remove the zone_id check statement, it's better handle this
rare race. This patch fixes this by placing the zone_id check before the
VM_BUG_ON_PAGE check.

Commit ed4d4902eb ("mm, hugetlb: remove hugetlb_zero and
hugetlb_infinity") replaced 'unsigned long hugetlb_zero' with 'int zero'
leading to out-of-bounds access in proc_doulongvec_minmax(). Use
'.extra1 = NULL' instead of '.extra1 = &zero'. Passing NULL is
equivalent to passing minimal value, which is 0 for unsigned types.

Whether there is a vm_ops->page_mkwrite or not, the page dirtying is
pretty much the same. Make sure the page references are the same in both
cases, then merge the two branches.
It's tempting to go even further and page-lock the !page_mkwrite case, to
get it in line with everybody else setting the page table and thus further
simplify the model. But that's not quite compelling enough to justify
dropping the pte lock, then relocking and verifying the entry for
filesystems without ->page_mkwrite, which notably includes tmpfs. Leave
it for now and lock the page late in the !page_mkwrite case.
