15d574fbd3 arm64: dts: sprd: Add clock properties for serial devices
We've introduced power management logics for the Spreadtrum serial
controller by commit 062ec2774c8a ("serial: sprd: Add power management
for the Spreadtrum serial controller"), thus add related clock properties
to support this feature.

d6e245acc9 arm64: tegra: Device tree fixes for v5.2-rc1
This contains one patch to disable the recently added XUSB support on
 Jetson TX2 which is reported to cause boot and CPU hotplug failures in
 some cases and doesn't allow the core power rail to be switched off.
 
 Furthermore there are some changes to enable IOMMU support on more
 devices. This is needed in order to prevent these devices from breaking
 with the policy change in the ARM SMMU driver to break insecure devices
 that is currently headed for v5.2.

22c58fd70c ARM: SoC platform updates
SoC updates, mostly refactorings and cleanups of old legacy platforms.
 Major themes this release:
 
  - Conversion of ixp4xx to a modern platform (drivers, DT, bindings)
  - Moving some of the ep93xx headers around to get it closer to multiplatform enabled.
  - Cleanups of Davinci
 
 This tag also contains a few patches that were queued up as fixes before
 5.1 but I didn't get sent in before release.

 "Just a small collection of fixes this time around.

  The new virtio-pmem driver is nearly ready, but some last minute
  device-mapper acks and virtio questions made it prudent to await v5.3.

  Other major topics that were brewing on the linux-nvdimm mailing list
  like sub-section hotplug, and other devm_memremap_pages() reworks will
  go upstream through Andrew's tree.

  Summary:

   - Restore the ability of the dax_pmem module to be built-in.

   - Harden the build for the 'nfit_test' unit test modules so that the

8a635ffb14 ia64: Make sure that we have a mmiowb function real early
Generic kernels feed many operation through the "machvec" logic to get
the correct form of the operation for the current system.  "mmiowb()" is
one of those operations.

Although machvec is initialized very early in boot, it isn't early
enough for a recent upstream kernel change that added mmiowb to the
spin_unlock() path.

Statically initialize the mmiowb field of machvec so that we won't die
with a call through a NULL pointer.  This should be safe because we do
the real initialization of machvec before bringing up any addtional CPUs
or doing any I/O.

Fixes: 49ca6462fc ("ia64/mmiowb: Add unconditional mmiowb() to arch_spin_unlock()")

700a800a94 This pull consists mostly of nfsd container work:
Scott Mayhew revived an old api that communicates with a userspace
 daemon to manage some on-disk state that's used to track clients across
 server reboots.  We've been using a usermode_helper upcall for that, but
 it's tough to run those with the right namespaces, so a daemon is much
 friendlier to container use cases.
 
 Trond fixed nfsd's handling of user credentials in user namespaces.  He
 also contributed patches that allow containers to support different sets
 of NFS protocol versions.
 
 The only remaining container bug I'm aware of is that the NFS reply
 cache is shared between all containers.  If anyone's aware of other gaps
 in our container support, let me know.
 
 The rest of this is miscellaneous bugfixes.

def0fdae81 mm: memcontrol: fix NUMA round-robin reclaim at intermediate level
When a cgroup is reclaimed on behalf of a configured limit, reclaim
needs to round-robin through all NUMA nodes that hold pages of the memcg
in question.  However, when assembling the mask of candidate NUMA nodes,
the code only consults the *local* cgroup LRU counters, not the
recursive counters for the entire subtree.  Cgroup limits are frequently
configured against intermediate cgroups that do not have memory on their
own LRUs.  In this case, the node mask will always come up empty and
reclaim falls back to scanning only the current node.

If a cgroup subtree has some memory on one node but the processes are
bound to another node afterwards, the limit reclaim will never age or
reclaim that memory anymore.

To fix this, use the recursive LRU counts for a cgroup subtree to
determine which nodes hold memory of that cgroup.

The code has been broken like this forever, so it doesn't seem to be a
problem in practice.  I just noticed it while reviewing the way the LRU
counters are used in general.

42a3003535 mm: memcontrol: fix recursive statistics correctness & scalabilty
Right now, when somebody needs to know the recursive memory statistics
and events of a cgroup subtree, they need to walk the entire subtree and
sum up the counters manually.

There are two issues with this:

1. When a cgroup gets deleted, its stats are lost. The state counters
   should all be 0 at that point, of course, but the events are not.
   When this happens, the event counters, which are supposed to be
   monotonic, can go backwards in the parent cgroups.

2. During regular operation, we always have a certain number of lazily
   freed cgroups sitting around that have been deleted, have no tasks,
   but have a few cache pages remaining. These groups' statistics do not
   change until we eventually hit memory pressure, but somebody
   watching, say, memory.stat on an ancestor has to iterate those every
   time.

This patch addresses both issues by introducing recursive counters at
each level that are propagated from the write side when stats change.

Upward propagation happens when the per-cpu caches spill over into the
local atomic counter.  This is the same thing we do during charge and
uncharge, except that the latter uses atomic RMWs, which are more
expensive; stat changes happen at around the same rate.  In a sparse
file test (page faults and reclaim at maximum CPU speed) with 5 cgroup
nesting levels, perf shows __mod_memcg_page state at ~1%.

205b20cc5a mm: memcontrol: make cgroup stats and events query API explicitly local
Patch series "mm: memcontrol: memory.stat cost & correctness".

The cgroup memory.stat file holds recursive statistics for the entire
subtree.  The current implementation does this tree walk on-demand
whenever the file is read.  This is giving us problems in production.

1. The cost of aggregating the statistics on-demand is high.  A lot of
   system service cgroups are mostly idle and their stats don't change
   between reads, yet we always have to check them.  There are also always
   some lazily-dying cgroups sitting around that are pinned by a handful
   of remaining page cache; the same applies to them.

   In an application that periodically monitors memory.stat in our
   fleet, we have seen the aggregation consume up to 5% CPU time.

2. When cgroups die and disappear from the cgroup tree, so do their
   accumulated vm events.  The result is that the event counters at
   higher-level cgroups can go backwards and confuse some of our
   automation, let alone people looking at the graphs over time.

To address both issues, this patch series changes the stat
implementation to spill counts upwards when the counters change.

The upward spilling is batched using the existing per-cpu cache.  In a
sparse file stress test with 5 level cgroup nesting, the additional cost
of the flushing was negligible (a little under 1% of CPU at 100% CPU
utilization, compared to the 5% of reading memory.stat during regular
operation).

This patch (of 4):

memcg_page_state(), lruvec_page_state(), memcg_sum_events() are
currently returning the state of the local memcg or lruvec, not the
recursive state.

In practice there is a demand for both versions, although the callers
that want the recursive counts currently sum them up by hand.

Per default, cgroups are considered recursive entities and generally we
expect more users of the recursive counters, with the local counts being
special cases.  To reflect that in the name, add a _local suffix to the
current implementations.

The following patch will re-incarnate these functions with recursive
semantics, but with an O(1) implementation.

6a02433065 drivers/virt/fsl_hypervisor.c: prevent integer overflow in ioctl
The "param.count" value is a u64 thatcomes from the user.  The code
later in the function assumes that param.count is at least one and if
it's not then it leads to an Oops when we dereference the ZERO_SIZE_PTR.

Also the addition can have an integer overflow which would lead us to
allocate a smaller "pages" array than required.  I can't immediately
tell what the possible run times implications are, but it's safest to
prevent the overflow.

871789d4af mm, memcg: rename ambiguously named memory.stat counters and functions
I spent literally an hour trying to work out why an earlier version of
my memory.events aggregation code doesn't work properly, only to find
out I was calling memcg->events instead of memcg->memory_events, which
is fairly confusing.

This naming seems in need of reworking, so make it harder to do the
wrong thing by using vmevents instead of events, which makes it more
clear that these are vm counters rather than memcg-specific counters.

There are also a few other inconsistent names in both the percpu and
aggregated structs, so these are all cleaned up to be more coherent and
easy to understand.

This commit contains code cleanup only: there are no logic changes.
