Currently, the Kbuild core manipulates header search paths in a crazy
way [1].
To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.
Having whitespaces after -I does not matter since commit 48f6e3cf5bc6
("kbuild: do not drop -I without parameter").

Convert to use vm_map_pages() to map range of kernel memory to user vma.
vm_pgoff is treated in V4L2 API as a 'cookie' to select a buffer, not as a
in-buffer offset by design and it always want to mmap a whole buffer from
its beginning.

Pach series "Add FOLL_LONGTERM to GUP fast and use it".
HFI1, qib, and mthca, use get_user_pages_fast() due to its performance
advantages. These pages can be held for a significant time. But
get_user_pages_fast() does not protect against mapping FS DAX pages.
Introduce FOLL_LONGTERM and use this flag in get_user_pages_fast() which
retains the performance while also adding the FS DAX checks. XDP has also
shown interest in using this functionality.[1]
In addition we change get_user_pages() to use the new FOLL_LONGTERM flag
and remove the specialized get_user_pages_longterm call.
[1] https://lkml.org/lkml/2019/3/19/939
"longterm" is a relative thing and at this point is probably a misnomer.
This is really flagging a pin which is going to be given to hardware and
can't move. I've thought of a couple of alternative names but I think we
have to settle on if we are going to use FL_LAYOUT or something else to
solve the "longterm" problem. Then I think we can change the flag to a
better name.
Secondly, it depends on how often you are registering memory. I have
spoken with some RDMA users who consider MR in the performance path...
For the overall application performance. I don't have the numbers as the
tests for HFI1 were done a long time ago. But there was a significant
advantage. Some of which is probably due to the fact that you don't have
to hold mmap_sem.
Finally, architecturally I think it would be good for everyone to use
*_fast. There are patches submitted to the RDMA list which would allow
the use of *_fast (they reworking the use of mmap_sem) and as soon as they
are accepted I'll submit a patch to convert the RDMA core as well. Also
to this point others are looking to use *_fast.
As an aside, Jasons pointed out in my previous submission that *_fast and
*_unlocked look very much the same. I agree and I think further cleanup
will be coming. But I'm focused on getting the final solution for DAX at
the moment.
This patch (of 7):
This patch starts a series which aims to support FOLL_LONGTERM in
get_user_pages_fast(). Some callers who would like to do a longterm (user
controlled pin) of pages with the fast variant of GUP for performance
purposes.
Rather than have a separate get_user_pages_longterm() call, introduce
FOLL_LONGTERM and change the longterm callers to use it.
This patch does not change any functionality. In the short term
"longterm" or user controlled pins are unsafe for Filesystems and FS DAX
in particular has been blocked. However, callers of get_user_pages_fast()
were not "protected".
FOLL_LONGTERM can _only_ be supported with get_user_pages[_fast]() as it
requires vmas to determine if DAX is in use.
NOTE: In merging with the CMA changes we opt to change the
get_user_pages() call in check_and_migrate_cma_pages() to a call of
__get_user_pages_locked() on the newly migrated pages. This makes the
code read better in that we are calling __get_user_pages_locked() on the
pages before and after a potential migration.
As a side affect some of the interfaces are cleaned up but this is not the
primary purpose of the series.
In review[1] it was asked:
<quote>

A couple of points.
First "longterm" is a relative thing and at this point is probably a
misnomer. This is really flagging a pin which is going to be given to

Pull drm updates from Dave Airlie:
"This has two exciting community drivers for ARM Mali accelerators.
Since ARM has never been open source friendly on the GPU side of the
house, the community has had to create open source drivers for the
Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx
series. Well done to all involved and hopefully this will help ARM
head in the right direction.
There is also now the ability if you don't have any of the legacy
drivers enabled (pre-KMS) to remove all the pre-KMS support code from
the core drm, this saves 10% or so in codesize on my machine.

Depending on which video standard is used the driver needs to setup the
hardware to correctly handle fields. If stream is identified as NTSC
or PAL setup field detection and propagate the field detection signal.
Later versions of the datasheet have been updated to make it clear
that FLD register should be set to 0 when dealing with non-interlaced
field formats.

Restart the CSI-2 link if the CSI-2 receiver detects an error during
reception. The driver did nothing when a link error happened and the
data flow simply stopped without the user knowing why.
Change the driver to try and recover from errors by restarting the link
and informing the user that something is not right. For obvious reasons
it's not possible to recover from all errors (video source disconnected
for example) but in such cases the user is at least informed of the
error and the same behavior of the stopped data flow is retained.

The "b->index" is a u32 the comes from the user in the ioctl. It hasn't
been checked. We aren't supposed to use it but we're instead supposed
to use the value that gets written to it when we call videobuf_dqbuf().
The videobuf_dqbuf() first memsets it to zero and then re-initializes it
inside the videobuf_status() function. It's this final value which we
want.
Hans Verkuil pointed out that we need to check the return from
videobuf_dqbuf(). I ended up doing a little cleanup related to that as
well.

In case the completion function failes, unbind will be called
which will call cancel_work for awb_work.
This will trigger a WARN message from the workqueue.
To avoid this, move the INIT_WORK call at the start of the completion

This will limit the incoming pixels per frame from the sensor.
Currently, the ISC will stop sampling the frame only when the vsync/hsync
are detected.
If we misconfigure the resolution in the sensor w.r.t. resolution in the ISC,
the buffer used for DMA in the ISC will be smaller than the number of pixels
that the ISC DMA engine will copy.
In this case it happens that the DMA will overwrite parts of the memory which
should not be written, leading to memory corruption.
To avoid this situation, use the PFE CFG1 and PFE CFG2 registers, which crop
the incoming frame to the resolution that we configure.
This way the DMA engine will never write more data than we expect it to.

$ make coccicheck MODE=patch COCCI=scripts/coccinelle/api/stream_open.cocci
I've verified each generated change manually - that it is correct to
convert - and each other nonseekable_open instance left - that it is
either not correct to convert there, or that it is not converted due
to current stream_open.cocci limitations. More details on this in the
patch.
- finally, change VFS to pass ppos=NULL into .read/.write for files
that declare themselves streams. It was suggested by Rasmus Villemoes
and makes sure that if ppos starts to be erroneously used in a stream
file, such bug won't go unnoticed and will produce an oops instead of
creating illusion of position change being taken into account.
Note: this patch does not conflict with "fuse: Add FOPEN_STREAM to
use stream_open()" that will be hopefully coming via FUSE tree,
because fs/fuse/ uses new-style .read_iter/.write_iter, and for these
accessors position is still passed as non-pointer kiocb.ki_pos .

Using scripts/coccinelle/api/stream_open.cocci added in 10dce8af3422
("fs: stream_open - opener for stream-like files so that read and write
can run simultaneously without deadlock"), search and convert to
stream_open all in-kernel nonseekable_open users for which read and
write actually do not depend on ppos and where there is no other methods
in file_operations which assume @offset access.
I've verified each generated change manually - that it is correct to convert -
and each other nonseekable_open instance left - that it is either not correct
to convert there, or that it is not converted due to current stream_open.cocci
limitations. The script also does not convert files that should be valid to
convert, but that currently have .llseek = noop_llseek or generic_file_llseek
for unknown reason despite file being opened with nonseekable_open (e.g.
drivers/input/mousedev.c)
Among cases converted 14 were potentially vulnerable to read vs write deadlock
(see details in 10dce8af3422):

One can also recheck/review the patch via generating it with explanation comments included via
$ make coccicheck MODE=patch COCCI=scripts/coccinelle/api/stream_open.cocci SPFLAGS="-D explain"
(*) This second group also contains cases with read/write deadlocks that
stream_open.cocci don't yet detect, but which are still valid to convert to
stream_open since ppos is not used. For example drivers/pci/switch/switchtec.c
calls wait_for_completion_interruptible() in its .read, but stream_open.cocci
currently detects only "wait_event*" as blocking.
