Merge tag 'folio-5.16' of git://git.infradead.org/users/willy/pagecache
Pull memory folios from Matthew Wilcox:
"Add memory folios, a new type to represent either order-0 pages or the
head page of a compound page. This should be enough infrastructure to
support filesystems converting from pages to folios.
The point of all this churn is to allow filesystems and the page cache
to manage memory in larger chunks than PAGE_SIZE. The original plan
was to use compound pages like THP does, but I ran into problems with
some functions expecting only a head page while others expect the
precise page containing a particular byte.
The folio type allows a function to declare that it's expecting only a
head page. Almost incidentally, this allows us to remove various calls
to VM_BUG_ON(PageTail(page)) and compound_head().
This converts just parts of the core MM and the page cache. For 5.17,
we intend to convert various filesystems (XFS and AFS are ready; other
filesystems may make it) and also convert more of the MM and page
cache to folios. For 5.18, multi-page folios should be ready.
The multi-page folios offer some improvement to some workloads. The
80% win is real, but appears to be an artificial benchmark (postgres
startup, which isn't a serious workload). Real workloads (eg building
the kernel, running postgres in a steady state, etc) seem to benefit
between 0-10%. I haven't heard of any performance losses as a result
of this series. Nobody has done any serious performance tuning; I
imagine that tweaking the readahead algorithm could provide some more
interesting wins. There are also other places where we could choose to
create large folios and currently do not, such as writes that are
larger than PAGE_SIZE.
I'd like to thank all my reviewers who've offered review/ack tags:
Christoph Hellwig, David Howells, Jan Kara, Jeff Layton, Johannes
Weiner, Kirill A. Shutemov, Michal Hocko, Mike Rapoport, Vlastimil
Babka, William Kucharski, Yu Zhao and Zi Yan.

With this change:
- before thread_info was part of the stack and located at the beginning of the stack
- now the thread_info struct is moved and located inside the task_struct structure
- the stack is allocated and handled like the major other platforms
- drop the cpu field of thread_info and use instead the one in task_struct

This swaps the descriptions of the 0 and 1 values to match
what the driver actually does with this property.
The background here is somewhat confusing. The codec has two
invert bits for the tip sense. The DT property should have been
for the TIP_SENSE_INV bit, which is the one that controls the
detect block. Due to some misunderstanding of the hardware the
driver actually implemented setting of the TS_INV bit, which is
only for swapping the sense of the interrupt bits. The description
was taken from the datasheet and refers to TIP_SENSE_INV but
unfortunately TS_INV has a different purpose and the net effect
of changing it is the reverse of what was intended (this is not
clearly described in the datasheet). So the ts-inv settings have
always done the exact opposite of what the description said.
Given the age of the driver, it's too late now to swap the meanings
of the values, so the description is changed to match the behaviour.
They have been annotated with the terminology used in the datasheet
to avoid the confusion of which one corresponds to what the datasheet
calls "inverted tip sense".

Mention the 'Link' tag in the section about adding URLs to the commit
msg, to make it clearer they "_primarily_ [...] should be about
background", as Linus recently stated (see the link below). That makes
the explanation also easier to find with a text search. For the same
reason and to improve comprehensibility provide an example, too.
Slightly improve the text at the same time to make it more obvious
developers are meant to add links to issue reports in mailing list
archives, as those allow regression tracking efforts to automatically
check which bugs got resolved.
Move the section also downwards slightly, to reduce jumping back and
forth between aspects relevant for the top and the bottom part of the
commit msg.

In some configurations, the BAM DMA controller is set up by a remote
processor and the local processor can simply start making use of it
without setting up the BAM. This is already supported using the
"qcom,controlled-remotely" property.
However, for some reason another possible configuration is that the
remote processor is responsible for powering up the BAM, but we are
still responsible for initializing it (e.g. resetting it etc). Add
a "qcom,powered-remotely" property to describe that configuration.

it never went to upstream. That's why fix example by using only 4 cells

Update the binding for ti-sysc interconnect target module driver to yaml
format.
Note that the old binding was never updated for the need to always specify
also the generic compatible "ti,sysc". This is needed for the auxdata
