Previously the negated unsigned long would be cast back to signed long
which would have the correct negative value. After commit 730ec8c01a2b
("mm/vmscan.c: change prototype for shrink_page_list"), the large
unsigned int converts to a large positive signed long.
Symptoms include CMA allocations hanging forever holding the cma_mutex
due to alloc_contig_range->...->isolate_migratepages_block waiting
forever in "while (unlikely(too_many_isolated(pgdat)))".

pages to migrate
In isolate_migratepages_block, if we have too many isolated pages and
nr_migratepages is not zero, we should try to migrate what we have
without wasting time on isolating.
In theory it's possible that multiple parallel compactions will cause
too_many_isolated() to become true even if each has isolated less than
COMPACT_CLUSTER_MAX, and loop forever in the while loop. Bailing
immediately prevents that.

In isolate_migratepages_block, when cc->alloc_contig is true, we are
able to isolate compound pages. But nr_migratepages and nr_isolated did
not count compound pages correctly, causing us to isolate more pages
than we thought.
So count compound pages as the number of base pages they contain.
Otherwise, we might be trapped in too_many_isolated while loop, since
the actual isolated pages can go up to COMPACT_CLUSTER_MAX*512=16384,
where COMPACT_CLUSTER_MAX is 32, since we stop isolation after
cc->nr_migratepages reaches to COMPACT_CLUSTER_MAX.
In addition, after we fix the issue above, cc->nr_migratepages could
never be equal to COMPACT_CLUSTER_MAX if compound pages are isolated,
thus page isolation could not stop as we intended. Change the isolation
stop condition to '>='.
The issue can be triggered as follows:
In a system with 16GB memory and an 8GB CMA region reserved by
hugetlb_cma, if we first allocate 10GB THPs and mlock them (so some THPs
are allocated in the CMA region and mlocked), reserving 6 1GB hugetlb
pages via /sys/kernel/mm/hugepages/hugepages-1048576kB/nr_hugepages will
get stuck (looping in too_many_isolated function) until we kill either
task. With the patch applied, oom will kill the application with 10GB
THPs and let hugetlb page reservation finish.

Some 360 degree hinges (yoga) style 2-in-1 devices use 2 KXCJ91008-s
to allow the OS to determine the angle between the display and the base
of the device, so that the OS can determine if the 2-in-1 is in laptop
or in tablet-mode.
On Windows both accelerometers are read by a special HingeAngleService
process; and this process calls a DSM (Device Specific Method) on the
ACPI KIOX010A device node for the sensor in the display, to let the
embedded-controller (EC) know about the mode so that it can disable the
kbd and touchpad to avoid spurious input while folded into tablet-mode.
This notifying of the EC is problematic because sometimes the EC comes up
thinking that device is in tablet-mode and the kbd and touchpad do not
work. This happens for example on Irbis NB111 devices after a suspend /
resume cycle (after a complete battery drain / hard reset without having
booted Windows at least once). Other 2-in-1s which are likely affected
too are e.g. the Teclast F5 and F6 series.
The kxcjk-1013 driver may seem like a strange place to deal with this,
but since it is *the* driver for the ACPI KIOX010A device, it is also
the driver which has access to the ACPI handle needed by the DSM.
Add support for calling the DSM and on probe unconditionally tell the
EC that the device is laptop mode, fixing the kbd and touchpad sometimes
not working.

Replace the boolean is_smo8500_device variable with an acpi_type enum.
For now this can be either ACPI_GENERIC or ACPI_SMO8500, this is a
preparation patch for adding special handling for the KIOX010A ACPI HID,
which will add a ACPI_KIOX010A acpi_type to the introduced enum.
For stable as needed as precursor for next patch.

Any attempt to do path resolution on /proc/self from an async worker will
yield -EOPNOTSUPP. We can safely do that resolution from the task itself,
and without blocking, so retry it from there.
Ideally io_uring would know this upfront and not have to go through the
worker thread to find out, but that doesn't currently seem feasible.

Currently verifier enforces return code checks for subprograms in the
same manner as it does for program entry points. This prevents returning
arbitrary scalar values from subprograms. Scalar type of returned values
is checked by btf_prepare_func_args() and hence it should be safe to
allow only scalars for now. Relax return code checks for subprograms and
allow any correct scalar values.

Git bisect has identified the following commit as bad:
f28e32d3906e drm/nouveau/kms: Don't change EDID when it hasn't actually changed
Here is the chain of events that causes the oops.
On entry to nouveau_connector_detect_lvds, edid is set to NULL. The call
to nouveau_connector_detect sets nv_connector->edid to valid memory,
with status set to connector_status_connected and the flow of execution
branching to the out label.
The subsequent call to nouveau_connector_set_edid erronously clears
nv_connector->edid, via the local edid pointer which remains set to NULL.
Fix this by setting edid to the value of the just acquired
nv_connector->edid and executing the body of nouveau_connector_set_edid
only if nv_connector->edid and edid point to different memory addresses
thus preventing nv_connector->edid from being turned into a dangling
pointer.

Pull fs freeze fix and cleanups from Darrick Wong:
"A single vfs fix for 5.10, along with two subsequent cleanups.
A very long time ago, a hack was added to the vfs fs freeze protection
code to work around lockdep complaints about XFS, which would try to
run a transaction (which requires intwrite protection) to finalize an
xfs freeze (by which time the vfs had already taken intwrite).
Fast forward a few years, and XFS fixed the recursive intwrite problem
on its own, and the hack became unnecessary. Fast forward almost a
decade, and latent bugs in the code converting this hack from freeze
flags to freeze locks combine with lockdep bugs to make this reproduce
frequently enough to notice page faults racing with freeze.
Since the hack is unnecessary and causes thread race errors, just get
rid of it completely. Making this kind of vfs change midway through a
cycle makes me nervous, but a large enough number of the usual
VFS/ext4/XFS/btrfs suspects have said this looks good and solves a
real problem vector.
And once that removal is done, __sb_start_write is now simple enough
that it becomes possible to refactor the function into smaller,
simpler static inline helpers in linux/fs.h. The cleanup is
straightforward.
Summary:
- Finally remove the "convert to trylock" weirdness in the fs freezer
code. It was necessary 10 years ago to deal with nested
transactions in XFS, but we've long since removed that; and now
this is causing subtle race conditions when lockdep goes offline
and sb_start_* aren't prepared to retry a trylock failure.
- Minor cleanups of the sb_start_* fs freeze helpers"

Commit 58956317c8de ("neighbor: Improve garbage collection")
guarantees neighbour table entries a five-second lifetime. Processes
which make heavy use of multicast can fill the neighour table with
multicast addresses in five seconds. At that point, neighbour entries
can't be GC-ed because they aren't five seconds old yet, the kernel
log starts to fill up with "neighbor table overflow!" messages, and
sends start to fail.
This patch allows multicast addresses to be thrown out before they've
lived out their five seconds. This makes room for non-multicast
addresses and makes messages to all addresses more reliable in these
circumstances.

The spin_lock/unlock_irq() functions cannot be nested. The problem is
that presumably we would want the IRQs to be re-enabled on the second
call the spin_unlock_irq() but instead it will be enabled at the first
call so IRQs will be enabled earlier than expected.
In this situation the copy_resp_to_buf() function is only called from
one function and it is called with IRQs disabled. We can just use
the regular spin_lock/unlock() functions.

From schema: /builds/robherring/linux-dt-bindings/Documentation/devicetree/bindings/net/can/fsl,flexcan.yaml
The error is fixed by replacing the "fsl,p1010-flexcan" compatible
(which turned out the be incompatible) with "fsl,imx25-flexcan" in the
binding example.

As both the i.MX35 and i.MX53 flexcan IP cores are compatible to the i.MX25,
they are listed as:
compatible = "fsl,imx35-flexcan", "fsl,imx25-flexcan";
and:
compatible = "fsl,imx53-flexcan", "fsl,imx25-flexcan";
in the SoC device trees.
This patch fixes the following errors, which shows up during a dtbs_check:
arch/arm/boot/dts/imx53-ard.dt.yaml: can@53fc8000: compatible: 'oneOf' conditional failed, one must be fixed:
['fsl,imx53-flexcan', 'fsl,imx25-flexcan'] is too long
Additional items are not allowed ('fsl,imx25-flexcan' was unexpected)
'fsl,imx53-flexcan' is not one of ['fsl,imx7d-flexcan', 'fsl,imx6ul-flexcan', 'fsl,imx6sx-flexcan']
'fsl,imx53-flexcan' is not one of ['fsl,ls1028ar1-flexcan']
'fsl,imx6q-flexcan' was expected
'fsl,lx2160ar1-flexcan' was expected

Renesas R-Car and RZ/G SoCs have a firmware download mode over USB.
However, on reset a banner string is transmitted out which is not expected
to be echoed back and will corrupt the protocol.

When the ucsi power supply goes online/offline, and when the
power levels change, the power supply class needs to be
notified so it can inform the user space.
