2020-03-20MAINTAINERS: adjust to filesystem doc ReST conversionLukas Bulwahn
Mauro's patch series <cover.1581955849.git.mchehab+huawei@kernel.org> ("[PATCH 00/44] Manually convert filesystem FS documents to ReST") converts many Documentation/filesystems/ files to ReST. Since then, ./scripts/get_maintainer.pl --self-test complains with 27 warnings on Documentation/filesystems/ of this kind: warning: no file matches F: Documentation/filesystems/... Adjust MAINTAINERS entries to all files converted from .txt to .rst in the patch series and address the 27 warnings.

2020-03-20Merge branch 'mauro' into docs-nextJonathan Corbet
Mauro says (as he's cleaning up my mess): This small series address a regression caused by a new patch at docs-next (and at linux-next). Before this patch, when a cross-reference to a chapter within the documentation is needed, we had to add a markup like: .. _foo: foo === This behavor is now different after this patch: 58ad30cf91f0 ("docs: fix reference to core-api/namespaces.rst") As a Sphinx extension now creates automatically a reference like the above, without requiring any extra markup. That, however, comes with a price: it is not possible anymore to have two sections with the same name within the entire Kernel docs! This causes thousands of warnings, as we have sections named "introduction" on lots of places. This series solve this regression by doing two changes: 1) The references are now prefixed by the document name. So, a file named "bar" would have the "foo" reference as "bar:foo". 2) It will only use the first two levels. The first one is (usually) the name of the document, and the second one the chapter name. This solves almost all problems we have. Still, there are a few places where we have two chapters at the same document with the same name. The first patch addresses this problem. The second patch limits the escope of the autosectionlabel.
2020-03-20docs: conf.py: avoid thousands of duplicate label warning on SphinxMauro Carvalho Chehab
The autosectionlabel extension is nice, as it allows to refer to a section by its name without requiring any extra tag to create a reference name. However, on its default, it has two serious problems: 1) the namespace is global. So, two files with different "introduction" section would create a label with the same name. This is easily solvable by forcing the extension to prepend the file name with: autosectionlabel_prefix_document = True 2) It doesn't work hierarchically. So, if there are two level 1 sessions (let's say, one labeled "open" and another one "ioctl") and both have a level 2 "synopsis" label, both section 2 will have the same identical name. Currently, there's no way to tell Sphinx to create an hierarchical reference like: open / synopsis ioctl / synopsis This causes around 800 warnings. So, the fix should be to not let autosectionlabel to produce references for anything that it is not at a chapter level within any doc, with: autosectionlabel_maxdepth = 2 Fixes: 58ad30cf91f0 ("docs: fix reference to core-api/namespaces.rst") Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Link: https://lore.kernel.org/r/74f4d8d91c648d7101c45b4b99cc93532f4dadc6.1584716446.git.mchehab+huawei@kernel.org Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2020-03-20docs: prevent warnings due to autosectionlabelMauro Carvalho Chehab
Changeset 58ad30cf91f0 ("docs: fix reference to core-api/namespaces.rst") enabled a new feature at Sphinx: it will now generate index for each document title, plus to each chapter inside it. There's a drawback, though: one document cannot have two sections with the same name anymore. A followup patch will change the logic of autosectionlabel to avoid most creating references for every single section title, but still we need to be able to reference the chapters inside a document. There are a few places where there are two chapters with the same name. This patch renames one of the chapters, in order to avoid symbol conflict within the same document.

2020-03-20bpf: Explicitly memset the bpf_attr structureGreg Kroah-Hartman
For the bpf syscall, we are relying on the compiler to properly zero out the bpf_attr union that we copy userspace data into. Unfortunately that doesn't always work properly, padding and other oddities might not be correctly zeroed, and in some tests odd things have been found when the stack is pre-initialized to other values.

So when we set MSG_MORE when: - We have more fragments coming in the batch, or - We have a more data to send in this PDU - We don't have a data digest trailer - We optimize with the SUCCESS flag and omit the NVMe completion (used if sq_head pointer update is disabled) This addresses a regression in QD=1 with SUCCESS flag optimization as we unconditionally set MSG_MORE when we didn't actually have more data to send.

2020-03-20irqchip/gic-v4.1: Map the ITS SGIR register pageMarc Zyngier
One of the new features of GICv4.1 is to allow virtual SGIs to be directly signaled to a VPE. For that, the ITS has grown a new 64kB page containing only a single register that is used to signal a SGI to a given VPE. Add a second mapping covering this new 64kB range, and take this opportunity to limit the original mapping to 64kB, which is enough to cover the span of the ITS registers.

2020-03-20irqchip/gic-v4.1: Ensure mutual exclusion betwen invalidations on the same RDMarc Zyngier
The GICv4.1 spec says that it is CONTRAINED UNPREDICTABLE to write to any of the GICR_INV{LPI,ALL}R registers if GICR_SYNCR.Busy == 1.

Before we finish the emulation and go back to guest, let's make sure the physical invalidate operation is actually completed and no stale data will be left in redistributor.

2020-03-20staging: mt7621-pci: use only two phys from device treeSergio Paracuellos
In order to align work with the mt7621-pci-phy part of the driver and device tree which is now using only two real phys one of them dual ported properly parse the device tree and don't call phy initialization for the slot 1 because is being taking into account when the phy for the slot 0 is instantiated.

2020-03-20staging: mt7621-dts: set up only two pcie physSergio Paracuellos
This soc has only two real pcie phys one of them having a different register to enable and disable it. Change this to have only two dt nodes for the phys and use 'phy-cells' properly to say if the phy has dual ports.

2020-03-20staging: mt7621-pci-phy: avoid to create to different phys for a dual port oneSergio Paracuellos
This soc has two phy's for the pcie one of them using just a different register for settig it up but sharing all the rest of the config. Until now we was presenting this schema as three different phy's in the device tree using the 'phy-cells' node property to discriminate an index and setting up a complete phy for the dual port index. This sometimes worked properly but reconfiguring the same registers twice presents sometimes some unstable pcie links and the ports was not properly being detected. The problems only appears on hard resets and soft resets was properly working. Instead of having this schema just set two phy's in the device ree and use the 'phy-cells' property to say if the port has or not a dual port. Doing this configuration and set up becomes easier, LOC is decreased and the behaviour also gets deterministic with properly and stable pcie links in both hard and soft resets.
