attached to it. In order to prevent the drivers to access the thermal
zone device structure, replace the thermal zone device by the driver

The traces are exported but only local to the thermal core code. On
the other side, the traces take the thermal zone device structure as
argument, thus they have to rely on the exported thermal.h header
file. As we want to move the structure to the private thermal core
header, first we have to relocate those traces to the same place as
many drivers do.

The thermal framework provides an API to get the trip related to a
trip point id. We want to consolidate the generic trip points code,
thus preventing the different drivers to deal with the trip points
after they registered them.
The set_trip_temp ops will be changed regarding the above changes but
first we need to rework a bit the different implementation in the
drivers.
The goal is to prevent using the trip id but use a trip point passed
as parameter which will contain all the needed information.
As we don't have the trip point passed as parameter yet, we get the
trip point using the generic trip thermal framewrok APIs and use it to
take exactly the same decisions.
The difference with this change and the previous code is from where we
get the thermal trip point (which is the same).
No functional change intended.

The thermal zone device structure is in the process of being private
to the thermal framework core code. This driver is directly accessing
and changing the monitoring polling rate.
After discussing with the maintainers of this driver, having the
polling interval at module loading time is enough for their purpose.
Change the code to take into account the interval when the module is
loaded but restrict the permissions so the value can not be changed
afterwards.

The function tegra_tsensor_enable_hw_channel() takes the thermal zone
lock to prevent "a potential" race with a call to set_trips()
callback.
The driver must not play with the thermal framework core code
internals.
The tegra_tsensor_enable_hw_channel() is called by:
- the suspend / resume callbacks
- the probe function after the thermal zones are registered
The thermal zone lock taken in this function is supposed to protect
from a call to the set_trips() callback which writes in the same
register.
The potential race is when suspend / resume are called at the same
time as set_trips. This one is called only in
thermal_zone_device_update().
- At suspend time, the 'in_suspend' is set, thus the
thermal_zone_device_update() bails out immediately and set_trips is
not called during this moment.
- At resume time, the thermal zone is updated at PM_POST_SUSPEND,
thus the driver has already set the TH2 temperature.
- At probe time, we register the thermal zone and then we set the
TH2. The only scenario I can see so far is the interrupt fires, the
thermal_zone_update() is called exactly at the moment
tegra_tsensor_enable_hw_channel() a few lines after registering it.
Enable the channels before setting up the interrupt. We close the
potential race window without using the thermal zone's lock.

Finally, some drivers are showing a debug message with the

other members of the union to access bit fields of it
- Add and use a READ_ONCE_ALIGNED_128() macro, which can be used to
atomically read a 128-bit value from memory. This replaces the (mis-)use
of the 128-bit cmpxchg operation to do the same in cpum_sf code.
Currently gcc does not generate the used lpq instruction if __READ_ONCE()
is used for aligned 128-bit accesses, therefore use this s390 specific
helper
- Simplify machine check handler code if a task needs to be killed because

- Generate arch/s390/boot/vmlinux.map link map for the decompressor, when

- Fix segment type handling for dcssblk devices. It incorrectly always
returned type "READ/WRITE" even for read-only segements, which can result

Commit 104ff59af7 ("ata: ahci: Add Tiger Lake UP{3,4} AHCI
controller") enabled low power mode for the Tiger Lake AHIC adapter in
the author system but created regressions for others. Revert this patch
for now until a better solution is found to make this adapter
eco-friendly.

The block layer might merge together discard requests up until the
max_discard_segments limit is hit, but blk_insert_cloned_request checks
the segment count against max_segments regardless of the req op. This
can result in errors like the following when discards are issued through
a DM device and max_discard_segments exceeds max_segments for the queue
of the chosen underlying device.
blk_insert_cloned_request: over max segments limit. (256 > 129)
Fix this by looking at the req_op and enforcing the appropriate segment
limit - max_discard_segments for REQ_OP_DISCARDs and max_segments for
everything else.

- In copy_highpage(), only reset the tag of the destination pointer if
KASAN_HW_TAGS is enabled so that user-space MTE does not interfere
with KASAN_SW_TAGS (which relies on top-byte-ignore).
- Remove warning if SME is detected without SVE, the kernel can cope
with such configuration (though none in the field currently).
- In cfi_handler(), pass the ESR_EL1 value to die() for consistency with
other die() callers.
- Disable HUGETLB_PAGE_OPTIMIZE_VMEMMAP on arm64 since the pte
manipulation from the generic vmemmap_remap_pte() does not follow the
required ARM break-before-make sequence (clear the pte, flush the
TLBs, set the new pte). It may be re-enabled once this sequence is
sorted.
- Fix possible memory leak in the arm64 ACPI code if the SMCCC version
and conduit checks fail.
- Forbid CALL_OPS with CC_OPTIMIZE_FOR_SIZE since gcc ignores
-falign-functions=N with -Os.
- Don't pretend KASLR is enabled if offset < MIN_KIMG_ALIGN as no
randomisation would actually take place.
