9852ae3fe5 mm, memcg: consider subtrees in memory.events
memory.stat and other files already consider subtrees in their output, and
we should too in order to not present an inconsistent interface.

The current situation is fairly confusing, because people interacting with
cgroups expect hierarchical behaviour in the vein of memory.stat,
cgroup.events, and other files.  For example, this causes confusion when
debugging reclaim events under low, as currently these always read "0" at
non-leaf memcg nodes, which frequently causes people to misdiagnose breach
behaviour.  The same confusion applies to other counters in this file when
debugging issues.

Aggregation is done at write time instead of at read-time since these
counters aren't hot (unlike memory.stat which is per-page, so it does it
at read time), and it makes sense to bundle this with the file
notifications.

After this patch, events are propagated up the hierarchy:

    [root@ktst ~]# cat /sys/fs/cgroup/system.slice/memory.events
    low 0
    high 0
    max 0
    oom 0
    oom_kill 0
    [root@ktst ~]# systemd-run -p MemoryMax=1 true
    Running as unit: run-r251162a189fb4562b9dabfdc9b0422f5.service
    [root@ktst ~]# cat /sys/fs/cgroup/system.slice/memory.events
    low 0
    high 0
    max 7
    oom 1
    oom_kill 1

As this is a change in behaviour, this can be reverted to the old
behaviour by mounting with the `memory_localevents' flag set.  However, we
use the new behaviour by default as there's a lack of evidence that there
are any current users of memory.events that would find this change
undesirable.

akpm: this is a behaviour change, so Cc:stable.  THis is so that
forthcoming distros which use cgroup v2 are more likely to pick up the
revised behaviour.

bec7550cca The Sphinx 2.0 release contained a few incompatible API changes that broke
our extensions and, thus, the documentation build in general.  Who knew
 that those deprecation warnings it was outputting actually meant we should
 change something?  This set of fixes makes the build work again with
 Sphinx 2.0 and eliminates the warnings for 1.8.  As part of that, we also
 need a few fixes to the docs for places where the new Sphinx is more
 strict.
 
 It is a bit late in the cycle for this kind of change, but it does fix
 problems that people are experiencing now.
 
 There has been some talk of raising the minimum version of Sphinx we
 support.  I don't want to do that abruptly, though, so these changes add
 some glue to continue to support versions back to 1.3.  We will be adding
 some infrastructure soon to nudge users of old versions forward, with the
 idea of maybe increasing our minimum version (and removing this glue)
 sometime in the future.

Switch to sphinx.util.logging to make this unsightly message go away.
Alas, that interface was only added in version 1.6, so we have to add a

a5325089bd arm64: Handle erratum 1418040 as a superset of erratum 1188873
We already mitigate erratum 1188873 affecting Cortex-A76 and
Neoverse-N1 r0p0 to r2p0. It turns out that revisions r0p0 to
r3p1 of the same cores are affected by erratum 1418040, which
has the same workaround as 1188873.

Let's expand the range of affected revisions to match 1418040,
and repaint all occurences of 1188873 to 1418040. Whilst we're
there, do a bit of reformating in silicon-errata.txt and drop
a now unnecessary dependency on ARM_ARCH_TIMER_OOL_WORKAROUND.

spi: dt-bindings: Convert Arm pl022 to json-schema
Convert the Arm pl022 binding to DT schema format. The clock binding was
missing, so it is added to the schema. It really should be required as
well, but there are some platforms (spear) not yet using DT clock
binding.

969f5ea627 arm64: errata: Add workaround for Cortex-A76 erratum #1463225
Revisions of the Cortex-A76 CPU prior to r4p0 are affected by an erratum
that can prevent interrupts from being taken when single-stepping.

This patch implements a software workaround to prevent userspace from
effectively being able to disable interrupts.

f42c104f2e Documentation: add TLS offload documentation
Describe existing kernel TLS offload (added back in Linux 4.19) -
the mechanism, the expected behavior and the notable corner cases.

This documentation is mostly targeting hardware vendors who want
to implement offload, to ensure consistency between implementations.

v2:
 - add emphasis around TLS_SW/TLS_HW/TLS_HW_RECORD;
 - remove mentions of ongoing work (Boris);
 - split the flow of data in SW vs. HW cases in TX overview
   (Boris);
 - call out which fields are updated by the device and which
   are filled by the stack (Boris);
 - move error handling into it's own section (Boris);
 - add more words about fallback (Boris);
 - note that checksum validation is required (Alexei);
 - note that drivers shouldn't pay attention to the TLS
   device features.

8d665693c2 dt-bindings: interrupt-controller: arm,gic: Fix schema errors in example
Validating the examples against the schema have a few errors:

arm,gic.example.dt.yaml: 'ranges' does not match any of the regexes: '^v2m@[0-9a-f]+$', 'pinctrl-[0-9]+'
arm,gic.example.dt.yaml: #address-cells:0:0: 2 is not one of [0, 1]
arm,gic.example.dt.yaml: #size-cells:0:0: 1 was expected

'ranges' is valid, but missing from the schema, so add it. The reg
addresses and sizes don't match the schema requirements and the example
template. We could just override the example template to use 64-bit
addresses, but there's not really any value showing that in the example.

If you want to see if your linker supports a certain flag, then ask the
linker directly with ld-option (not the compiler with cc-ldoption).
Checking for linker flag support is an antipattern that complicates the

Pull i2c updates from Wolfram Sang:
 "Some I2C core API additions which are kind of simple but enhance error
  checking for users a lot, especially by returning errno now.

  There are wrappers to still support the old API but it will be removed
  once all users are converted"

4c4a5c99af ARM: SoC: late updates
This is some material that we picked up into our tree late. Most of it
 are smaller fixes and additions, some defconfig updates due to recent
 development, etc.
 
 Code-wise the largest portion is a series of PM updates for the at91
 platform, and those have been in linux-next a while through the at91
 tree before we picked them up.

b0bb1269b9 RISC-V Patches for the 5.2 Merge Window, Part 1 v3
This patch set contains an assortment of RISC-V related patches that I'd
 like to target for the 5.2 merge window.  Most of the patches are
 cleanups, but there are a handful of user-visible changes:
 
 * The nosmp and nr_cpus command-line arguments are now supported, which
   work like normal.
 * The SBI console no longer installs itself as a preferred console, we
   rely on standard mechanisms (/chosen, command-line, hueristics)
   instead.
 * sfence_remove_sfence_vma{,_asid} now pass their arguments along to the
   SBI call.
 * Modules now support BUG().
 * A missing sfence.vma during boot has been added.  This bug only
   manifests during boot.
 * The arch/riscv support for SiFive's L2 cache controller has been
   merged, which should un-block the EDAC framework work.
 
 I've only tested this on QEMU again, as I didn't have time to get things
 running on the Unleashed.  The latest master from this morning merges in
 cleanly and passes the tests as well.
 
 This patch set rebased my "5.2 MW, Part 1" patch set which includes an
 erronous empty file.  It's also a rebase of my "5.2 MW, Part 2" patch
 set, in which I managed to create another file while attempting to
 remove the empty file.
 
 Sorry for all the noise!
