4c4e17f270 clk: amlogic: naming consistency alignment
Amlogic clock controller drivers are all doing the same thing, more or
less. Yet, over the years, tiny (and often pointless) differences have
emerged.

This makes reviews more difficult, allows some errors to slip through and
make it more difficult to exploit SoC commonalities, leading to code
duplication.

This change enforce, wherever possible, a consistent and predictable scheme
when it comes to code organisation and naming, The scheme chosen is what
was used the most already, to try and minimise the size of the ugly
resulting diff. Here are some of the rules applied:
- Aligning clock names, variable names and IDs.
  - ID cannot change (used in DT)
  - Variable names w/ SoC name prefixes
  - Clock names w/o SoC name prefixes, except pclks for historic reasons
- Composite clock systematic naming : mux: X_sel, div:X_div, gate:X
- Parent table systematically named with the same name as the clock and
  a '_parents' suffix
- Group various tables next to the related clock
- etc ...

Doing so removes what would otherwise show up as unrelated diff in
following changes. It will allow to introduce common definitions for
peripheral clocks, probe helpers, composite clocks, etc ... making further
review and maintenance easier.

1d57628ff9 dm-pcache: add persistent cache target in device-mapper
This patch introduces dm-pcache, a new DM target that places a DAX-
capable persistent-memory device in front of any slower block device and
uses it as a high-throughput, low-latency  cache.

Design highlights
-----------------
- DAX data path – data is copied directly between DRAM and the pmem
  mapping, bypassing the block layer’s overhead.

- Segmented, crash-consistent layout
  - all layout metadata are dual-replicated CRC-protected.
  - atomic kset flushes; key replay on mount guarantees cache integrity
    even after power loss.

- Striped multi-tree index
  - Multi‑tree indexing for high parallelism.
  - overlap-resolution logic ensures non-intersecting cached extents.

- Background services
  - write-back worker flushes dirty keys in order, preserving backing-device
    crash consistency. This is important for checkpoint in cloud storage.
  - garbage collector reclaims clean segments when utilisation exceeds a
    tunable threshold.

- Data integrity – optional CRC32 on cached payload; metadata always protected.

feb500c7ae iio: xilinx-ams: Unmask interrupts after updating alarms
To convert level-triggered alarms into edge-triggered IIO events, alarms
are masked when they are triggered. To ensure we catch subsequent
alarms, we then periodically poll to see if the alarm is still active.
If it isn't, we unmask it. Active but masked alarms are stored in
current_masked_alarm.

If an active alarm is disabled, it will remain set in
current_masked_alarm until ams_unmask_worker clears it. If the alarm is
re-enabled before ams_unmask_worker runs, then it will never be cleared
from current_masked_alarm. This will prevent the alarm event from being
pushed even if the alarm is still active.

Fix this by recalculating current_masked_alarm immediately when enabling
or disabling alarms.

platform/x86: asus-wmi: Fix ROG button mapping, tablet mode on ASUS ROG Z13
On commit 9286dfd573 ("platform/x86: asus-wmi: Fix spurious rfkill on
UX8406MA"), Mathieu adds a quirk for the Zenbook Duo to ignore the code
0x5f (WLAN button disable). On that laptop, this code is triggered when
the device keyboard is attached.

On the ASUS ROG Z13 2025, this code is triggered when pressing the side
button of the device, which is used to open Armoury Crate in Windows.

As this is becoming a pattern, where newer Asus laptops use this keycode
for emitting events, let's convert the wlan ignore quirk to instead
allow emitting codes, so that userspace programs can listen to it and
so that it does not interfere with the rfkill state.

With this patch, the Z13 wil emit KEY_PROG3 and the Duo will remain
unchanged and emit no event. While at it, add a quirk for the Z13 to
switch into tablet mode when removing the keyboard.

platform/x86: asus-wmi: Remove extra keys from ignore_key_wlan quirk
Currently, the ignore_key_wlan quirk applies to keycodes 0x5D, 0x5E, and
0x5F. However, the relevant code for the Asus Zenbook Duo is only 0x5F.
Since this code is emitted by other Asus devices, such as from the Z13
for its ROG button, remove the extra codes before expanding the quirk.

For the Duo devices, which are the only ones that use this quirk, there
should be no effect.

a20b83cf45 nios2: ensure that memblock.current_limit is set when setting pfn limits
On nios2, with CONFIG_FLATMEM set, the kernel relies on
memblock_get_current_limit() to determine the limits of mem_map, in
particular for max_low_pfn.
Unfortunately, memblock.current_limit is only default initialized to
MEMBLOCK_ALLOC_ANYWHERE at this point of the bootup, potentially leading
to situations where max_low_pfn can erroneously exceed the value of
max_pfn and, thus, the valid range of available DRAM.

This can in turn cause kernel-level paging failures, e.g.:

[   76.900000] Unable to handle kernel paging request at virtual address 20303000
[   76.900000] ea = c0080890, ra = c000462c, cause = 14
[   76.900000] Kernel panic - not syncing: Oops
[   76.900000] ---[ end Kernel panic - not syncing: Oops ]---

This patch fixes this by pre-calculating memblock.current_limit
based on the upper limits of the available memory ranges via
adjust_lowmem_bounds, a simplified version of the equivalent
implementation within the arm architecture.

e6d8afd2ca nios2: Replace __ASSEMBLY__ with __ASSEMBLER__ in non-uapi headers
While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembly code, __ASSEMBLY__ is a
macro that only gets defined by the Makefiles in the kernel.
This can be very confusing when switching between userspace
and kernelspace coding, or when dealing with uapi headers that
rather should use __ASSEMBLER__ instead. So let's standardize on
the __ASSEMBLER__ macro that is provided by the compilers now.

This is a completely mechanical patch (done with a simple "sed -i"
statement).

60ad9a0731 iio: core: switch info_mask fields to unsigned long to match find_bit helpers
for_each_set_bit()/find_*_bit() expect arrays of unsigned long (see
include/linux/find.h), but industrialio-core passed const long * into
iio_device_add_info_mask_type{,_avail}().

These masks are used purely as bit arrays and are populated via BIT()
(1UL << n). Switch the info_mask_* fields and the corresponding function
parameters to unsigned long so the types match the helpers. This removes
sparse warnings about signedness mismatches (seen with 'make C=1'
CF='-Wsparse-all') without changing behavior or struct layout.

No functional change intended.
