2019-06-13arm64/sve: Fix missing SVE/FPSIMD endianness conversionsDave Martin1-0/+16
The in-memory representation of SVE and FPSIMD registers is different: the FPSIMD V-registers are stored as single 128-bit host-endian values, whereas SVE registers are stored in an endianness-invariant byte order. This means that the two representations differ when running on a big-endian host. But we blindly copy data from one representation to another when converting between the two, resulting in the register contents being unintentionally byteswapped in certain situations. Currently this can be triggered by the first SVE instruction after a syscall, for example (though the potential trigger points may vary in future). So, fix the conversion functions fpsimd_to_sve(), sve_to_fpsimd() and sve_sync_from_fpsimd_zeropad() to swab where appropriate. There is no common swahl128() or swab128() that we could use here. Maybe it would be worth making this generic, but for now add a simple local hack. Since the byte order differences are exposed in ABI, also clarify the documentation.

2019-06-01mm, memcg: consider subtrees in memory.eventsChris Down1-0/+9
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.

Pull documentation fixes from Jonathan Corbet: "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" * tag 'docs-5.2-fixes2' of git://git.lwn.net/linux: drm/i915: Maintain consistent documentation subsection ordering scripts/sphinx-pre-install: make it handle Sphinx versions docs: Fix conf.py for Sphinx 2.0 docs: fix multiple doc build warnings in enumeration.rst lib/list_sort: fix kerneldoc build error docs: fix numaperf.rst and add it to the doc tree doc: Cope with the deprecation of AutoReporter doc: Cope with Sphinx logging deprecations
2019-05-29media: dt-bindings: media: sun6i-csi: Add compatible string for A83T variantChen-Yu Tsai1-0/+1
The A83T SoC has a camera sensor interface (known as CSI in Allwinner lingo), which is similar to the one found on the A64 and H3. The only difference seems to be that support of MIPI CSI through a connected MIPI CSI-2 bridge. Add a compatible string for this variant.

AutoReporter is going away; recent versions of sphinx emit a warning like: Documentation/sphinx/kerneldoc.py:125: RemovedInSphinx20Warning: AutodocReporter is now deprecated. Use sphinx.util.docutils.switch_source_input() instead. Make the switch. But switch_source_input() only showed up in 1.7, so we have to do ugly version checks to keep things working in older versions.
