The vDSO library should only include the necessary headers required for
a userspace library (UAPI and a minimal set of kernel headers). To make
this possible it is necessary to isolate from the kernel headers the
common parts that are strictly necessary to build the library.
Split jiffies.h into linux and common headers to make the latter suitable
for inclusion in the vDSO library.

Sometimes, more than one (generally two) device can point to the same
fwnode. However, only one device is set as the fwnode's device
(fwnode->dev) and can be looked up from the fwnode.
Typically, only one of these devices actually have a driver and actually
probe. If we create device links for all these devices, then the
suppliers' of these devices (with the same fwnode) will never get a
sync_state() call because one of their consumer devices will never probe
(because they don't have a driver).
So, create device links only for the device that is considered as the
fwnode's device.
One such example of this is the PCI bridge platform_device and the
corresponding pci_bus device. Both these devices will have the same
fwnode. It's the platform_device that is registered first and is set as
the fwnode's device. Also the platform_device is the one that actually
probes. Without this patch none of the suppliers of a PCI bridge
platform_device would get a sync_state() callback.

There is no special reason to set virtual LPI pending table as
non-shareable. If we choose to hard code the shareability without
probing, Inner-Shareable is likely to be a better choice, as the
VPEs can move around and benefit from having the redistributors
snooping each other's cache, if that's something they can do.
Furthermore, Hisilicon hip08 ends up with unspecified errors when
mixing shareability attributes. So let's move to IS attributes for
the VPT. This has also been tested on D05 and didn't show any
regression.

Making gpio8 and gpio9 vendor specific and putting them
into the specific dts file makes not needed to release
gpios anymore because we are not occupying those pins
in the first place if it is not necessary. When the
device tree is parsed we can also check and return for
the error because we rely in the fact that the related
device for the board is correct.

There are three pins that can be used for reset gpios.
As mentioned in the application note, there are two
possible way of wiring pcie reset:
* connect gpio19 to all pcie reset pins
* connect gpio19 to pcie0 reset and pick two other
gpios for pcie1 and pcie2
gpio7 and gpio8 may not be used as pcie reset and are
vendor specific. Hence, maintain common mt7621.dtsi with
only gpio19 which is common and make an overlay for gnubee
board which uses all gpio's as resets for pcie. After this
changes release gpios in driver code is not needed anymore.

Phy for slot 0 and 1 is shared and handled properly in slot 0.
If there is only one port in use,(slot 0) we shall not call the
'phy_power_off' function with an invalid slot because kernel
will crash with an unaligned access fault like the following:

Linus continues to remind[1] people to stop using the BUG()-family of
functions. We should have this better documented (even if checkpatch.pl
has been warning[2] since 2015), so add more details to deprecated.rst,
as a distinct place to point people to for guidance.

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.
|

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

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.

We are incorrectly dropping the raid56 and raid1c34 incompat flags when
there are still raid56 and raid1c34 block groups, not when we do not any
of those anymore. The logic just got unintentionally broken after adding
the support for the raid1c34 modes.
Fix this by clear the flags only if we do not have block groups with the
respective profiles.

Trying to initialize a structure with "= {};" will not always clean out
all padding locations in a structure. So be explicit and call memset to
initialize everything for a number of bpf information structures that
are then copied from userspace, sometimes from smaller memory locations
than the size of the structure.

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.
Fix this by explicitly memsetting the structure to 0 before using it.

When we send PDU data, we want to optimize the tcp stack
operation if we have more data to send. 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.

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.

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.
To deal with it, we must ensure that only a single invalidation can
happen at a time for a given redistributor. Add a per-RD lock to that
effect and take it around the invalidation/syncr-read to deal with this.

In GICv4.1, we emulate a guest-issued INVALL command by a direct write
to GICR_INVALLR. 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. Per the specification,
this can be achieved by polling the GICR_SYNCR.Busy bit (to zero).
