The multi-chip module MT7530 switch with a 40 MHz oscillator on the
MT7621AT, MT7621DAT, and MT7621ST SoCs forwards corrupt frames using
trgmii.
This is caused by the assumption that MT7621 SoCs have got 150 MHz PLL,
hence using the ncpo1 value, 0x0780.
My testing shows this value works on Unielec U7621-06, Bartel's testing
shows it won't work on Hi-Link HLK-MT7621A and Netgear WAC104. All devices
tested have got 40 MHz oscillators.
Using the value for 125 MHz PLL, 0x0640, works on all boards at hand. The
definitions for 125 MHz PLL exist on the Banana Pi BPI-R2 BSP source code
whilst 150 MHz PLL don't.
Forwarding frames using trgmii on the MCM MT7530 switch with a 25 MHz
oscillator on the said MT7621 SoCs works fine because the ncpo1 value
defined for it is for 125 MHz PLL.
Change the 150 MHz PLL comment to 125 MHz PLL, and use the 125 MHz PLL
ncpo1 values for both oscillator frequencies.

Seemingly I mis-implemented the dependencies here. The OpenSBI docs only
point out that the "riscv,event-to-mhpmcounters property is mandatory if
riscv,event-to-mhpmevent is present". It never claims that
riscv,event-to-mhpmcounters requires riscv,event-to-mhpmevent.
Drop the dependency of riscv,event-to-mhpmcounters on
riscv,event-to-mhpmevent.

This pull request includes a number of patches that didn't quite make
the cut last merge window while we addressed some outstanding issues
and review comments. It includes some new caching modes for those that
only want readahead caches and reworks how we do writeback caching so we
are not keeping extra references around which both causes performance problems
and uses lots of additional resources on the server.
It also includes a new flag to force disabling of xattrs which can also
cause major performance issues, particularly if the underlying filesystem
on the server doesn't support them.
Finally it adds a couple of additional mount options to better support
directio and enabling caches when the server doesn't support qid.version.
There was one late-breaking bug report that has also been included as its
own patch where I forgot to propagate an embarassing bit-logic fix to the
various variations of open. Since that was only added to for-next a week

If cur_state for the powerclamp cooling device is set to the default
minimum state of 0, without setting first to cur_state > 0, this results
in NULL pointer access.
This NULL pointer access happens in the powercap core idle-inject
function idle_inject_set_duration() as there is no NULL check for
idle_inject_device pointer. This pointer must be allocated by calling
idle_inject_register() or idle_inject_register_full().
In the function powerclamp_set_cur_state(), idle_inject_device pointer
is allocated only when the cur_state > 0. But setting 0 without changing
to any other state, idle_inject_set_duration() will be called with a
NULL idle_inject_device pointer.
To address this, just return from powerclamp_set_cur_state() if the
current cooling device state is the same as the last one. Since the
power-up default cooling device state is 0, changing the state to 0
again here will return without calling idle_inject_set_duration().

Remove the acpi_backlight=video quirk for Lenovo ThinkPad W530.
This was intended to help users of the (unsupported) Nvidia binary driver,
but this has been reported to cause backlight control issues for users
who have the gfx configured in hybrid (dual-GPU) mode, so drop this.
The Nvidia binary driver should call acpi_video_register_backlight()
when necessary and this has been reported to Nvidia.
Until this is fixed Nvidia binary driver users can work around this by
passing "acpi_backlight=video" on the kernel commandline (with the latest

Fix a potential race in gmap_make_secure() and remove the last user of
follow_page() without FOLL_GET.
The old code is locking something it doesn't have a reference to, and
as explained by Jason and David in this discussion:
https://lore.kernel.org/linux-mm/Y9J4P%2FRNvY1Ztn0Q@nvidia.com/
it can lead to all kind of bad things, including the page getting
unmapped (MADV_DONTNEED), freed, reallocated as a larger folio and the
unlock_page() would target the wrong bit.
There is also another race with the FOLL_WRITE, which could race
between the follow_page() and the get_locked_pte().
The main point is to remove the last use of follow_page() without
FOLL_GET or FOLL_PIN, removing the races can be considered a nice
bonus.

On machines without the Destroy Secure Configuration Fast UVC, the
topmost level of page tables is set aside and freed asynchronously
as last step of the asynchronous teardown.
Each gmap has a host_to_guest radix tree mapping host (userspace)
addresses (with 1M granularity) to gmap segment table entries (pmds).
If a guest is smaller than 2GB, the topmost level of page tables is the
segment table (i.e. there are only 2 levels). Replacing it means that
the pointers in the host_to_guest mapping would become stale and cause
all kinds of nasty issues.
This patch fixes the issue by disallowing asynchronous teardown for
guests with only 2 levels of page tables. Userspace should (and already
does) try using the normal destroy if the asynchronous one fails.
Update s390_replace_asce so it refuses to replace segment type ASCEs.
This is still needed in case the normal destroy VM fails.

Once command submission failed due to userptr invalidation in
amdgpu_cs_submit, legacy code will perform cleanup of scheduler
job. However, it's not needed at all, as former commit has integrated
job cleanup stuff into amdgpu_job_free. Otherwise, because of double
free, a NULL pointer dereference will occur in such scenario.

[Why]
Reading pipe_fuses from register may have invalid bits set, which may
affect the num_pipes erroneously.
[How]
Add read_pipes_fuses() call and filter bits based on expected number
of pipes.

[Why]
This WPTR_POLL_ENABLE is a hardware contigious polling which will cause
FCLK and UCLK to keep on a high level.
Mostly its case can be covered by F32_WPTR_POLL_ENABLE which polls by
firmware.
So to save power, SR-IOV also needs to disable this bit

That time is now and things are looking good. We only have one stragglers
on the patch which had already an ACK for so I'm picking this up here now and
the last patch is the one that uses an axe. Some careful eyeballing would
be appreciated by others. If this doesn't get properly reviewed I can also
just hold off on this in my tree for the next merge window. Either way is
fine by me.
I have boot tested the last patch and 0-day build completed successfully.

Merge tag 'thermal-6.4-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more thermal control updates from Rafael Wysocki:
"These are mostly cleanups on top of the previously merged thermal
control changes plus some driver fixes and the removal of the Intel
Menlow thermal driver.
Specifics:
- Add compatible DT bindings for imx6sll and imx6ul to fix a dtbs
check warning (Stefan Wahren)
- Update the example in the DT bindings to reflect changes with the
ADC node name for QCom TM and TM5 (Marijn Suijten)
- Fix comments for the cpuidle_cooling_register() function to match
the function prototype (Chenggang Wang)
- Fix inconsistent temperature read and some Mediatek variant board
reboot by reverting a change and handling the temperature
differently (AngeloGioacchino Del Regno)
- Fix a memory leak in the initialization error path for the Mediatek
driver (Kang Chen)
- Use of_address_to_resource() in the Mediatek driver (Rob Herring)
- Fix unit address in the QCom tsens driver DT bindings (Krzysztof
Kozlowski)
- Clean up the step-wise thermal governor (Zhang Rui)
- Introduce thermal_zone_device() for accessing the device field of
struct thermal_zone_device and two drivers use it (Daniel Lezcano)
- Clean up the ACPI thermal driver a bit (Daniel Lezcano)
- Delete the thermal driver for Intel Menlow platforms that is not
expected to have any users (Rafael Wysocki)"

Dave Hansen found the "(long) addr >= 0" code in the x86-64 access_ok
checks somewhat confusing, and suggested using a helper to clarify what
the code is doing.
So this does exactly that: clarifying what the sign bit check is all
about, by adding a helper macro that makes it clear what it is testing.
This also adds some explicit comments talking about how even with LAM
enabled, any addresses with the sign bit will still GP-fault in the
non-canonical region just above the sign bit.
This is all what allows us to do the user address checks with just the
sign bit, and furthermore be a bit cavalier about accesses that might be
done with an additional offset even past that point.
(And yes, this talks about 'positive' even though zero is also a valid
user address and so technically we should call them 'non-negative'. But
I don't think using 'non-negative' ends up being more understandable).

The intent of the sign games was to not modify kernel addresses when
untagging them. However, that had two issues:
(a) it didn't actually work as intended, since the mask was calculated
as 'addr >> 63' on an _unsigned_ address. So instead of getting a
mask of all ones for kernel addresses, you just got '1'.
(b) untagging a kernel address isn't actually a valid operation anyway.
Now, (a) had originally been true for both 'untagged_addr()' and the
remote version of it, but had accidentally been fixed for the regular
version of untagged_addr() by commit e0bddc19ba ("x86/mm: Reduce
untagged_addr() overhead for systems without LAM"). That one rewrote
the shift to be part of the alternative asm code, and in the process
changed the unsigned shift into a signed 'sar' instruction.
And while it is true that we don't want to turn what looks like a kernel
address into a user address by masking off the high bit, that doesn't
need these sign masking games - all it needs is that the mm context
'untag_mask' value has the high bit set.
Which it always does.
So simplify the code by just removing the superfluous (and in the case
of untagged_addr_remote(), still buggy) sign bit games in the address
masking.

The x86 <asm/uaccess.h> file has grown features that are specific to
x86-64 like LAM support and the related access_ok() changes. They
really should be in the <asm/uaccess_64.h> file and not pollute the
generic x86 header.
