After commit acd7ccb284b8 ("mm: shmem: add large folio support for
tmpfs"), we have extended tmpfs to allow any sized large folios, rather
than just PMD-sized large folios.
The strategy discussed previously was:
: Considering that tmpfs already has the 'huge=' option to control the
: PMD-sized large folios allocation, we can extend the 'huge=' option to
: allow any sized large folios. The semantics of the 'huge=' mount option
: are:
:
: huge=never: no any sized large folios
: huge=always: any sized large folios
: huge=within_size: like 'always' but respect the i_size
: huge=advise: like 'always' if requested with madvise()
:
: Note: for tmpfs mmap() faults, due to the lack of a write size hint, still
: allocate the PMD-sized huge folios if huge=always/within_size/advise is
: set.
:
: Moreover, the 'deny' and 'force' testing options controlled by
: '/sys/kernel/mm/transparent_hugepage/shmem_enabled', still retain the same
: semantics. The 'deny' can disable any sized large folios for tmpfs, while
: the 'force' can enable PMD sized large folios for tmpfs.
This means that when tmpfs is mounted with 'huge=always' or
'huge=within_size', tmpfs will allow getting a highest order hint based on
the size of write() and fallocate() paths. It will then try each
allowable large order, rather than continually attempting to allocate
PMD-sized large folios as before.
However, this might break some user scenarios for those who want to use
PMD-sized large folios, such as the i915 driver which did not supply a
write size hint when allocating shmem [1].
Moreover, Hugh also complained that this will cause a regression in userspace
with 'huge=always' or 'huge=within_size'.
So, let's revisit the strategy for tmpfs large page allocation. A simple fix
would be to always try PMD-sized large folios first, and if that fails, fall
back to smaller large folios. This approach differs from the strategy for
large folio allocation used by other file systems, however, tmpfs is somewhat
different from other file systems, as quoted from David's opinion:
: There were opinions in the past that tmpfs should just behave like any
: other fs, and I think that's what we tried to satisfy here: use the write
: size as an indication.
:
: I assume there will be workloads where either approach will be beneficial.
: I also assume that workloads that use ordinary fs'es could benefit from
: the same strategy (start with PMD), while others will clearly not.

Patch series "introduce kasan.write_only option in hw-tags", v8.
Hardware tag based KASAN is implemented using the Memory Tagging Extension
(MTE) feature.
MTE is built on top of the ARMv8.0 virtual address tagging TBI (Top Byte
Ignore) feature and allows software to access a 4-bit allocation tag for
each 16-byte granule in the physical address space. A logical tag is
derived from bits 59-56 of the virtual address used for the memory access.
A CPU with MTE enabled will compare the logical tag against the
allocation tag and potentially raise an tag check fault on mismatch,
subject to system registers configuration.
Since ARMv8.9, FEAT_MTE_STORE_ONLY can be used to restrict raise of tag
check fault on store operation only.
Using this feature (FEAT_MTE_STORE_ONLY), introduce KASAN write-only mode
which restricts KASAN check write (store) operation only. This mode omits
KASAN check for read (fetch/load) operation. Therefore, it might be used
not only debugging purpose but also in normal environment.
This patch (of 2):
Since Armv8.9, FEATURE_MTE_STORE_ONLY feature is introduced to restrict
raise of tag check fault on store operation only. Introduce KASAN write
only mode based on this feature.
KASAN write only mode restricts KASAN checks operation for write only and
omits the checks for fetch/read operations when accessing memory. So it
might be used not only debugging enviroment but also normal enviroment to
check memory safty.
This features can be controlled with "kasan.write_only" arguments. When
"kasan.write_only=on", KASAN checks write operation only otherwise KASAN
checks all operations.
This changes the MTE_STORE_ONLY feature as BOOT_CPU_FEATURE like
ARM64_MTE_ASYMM so that makes it initialise in kasan_init_hw_tags() with
other function together.

With zswap using zsmalloc directly, there are no more in-tree users of
this code. Remove it.
With zpool gone, zsmalloc is now always a simple dependency and no
longer something the user needs to configure. Hide CONFIG_ZSMALLOC
from the user and have zswap and zram pull it in as needed.

Introduce binding documentation for system clocks, functional clocks,
and PEXTP0/1 and UFS reset controllers on MediaTek MT8196.
This binding also includes a handle to the hardware voter, a
fixed-function MCU designed to aggregate votes from the application
processor and other remote processors to manage clocks and power
domains.
The HWV on MT8196/MT6991 is incomplete and requires software to manually
enable power supplies, parent clocks, and FENC, as well as write to both
the HWV MMIO and the controller registers.
Because of these constraints, the HWV cannot be modeled using generic
clock, power domain, or interconnect APIs. Instead, a custom phandle is
exceptionally used to provide direct, syscon-like register access to
drivers.

ASoC: Updates for v6.18
A relatively quiet release for ASoC, we've had a lot of maintainance
work going on and several new drivers but really the most remarkable
thing is that we removed a driver, the WL1273 driver used in some old
Nokia systems that have had the underlying system support removed from
the kernel.
- Morimoto-san continues his work on cleanups of the core APIs and
enforcement of abstraction layers.
- Lots of cleanups and conversions of DT bindings.
- Substantial maintainance work on the Intel AVS drivers.
- Support for Qualcomm Glymur and PM4125, Realtek RT1321, Shanghai
FourSemi FS2104/5S, Texas Instruments PCM1754.
- Remove support for TI WL1273.

Various network interface types make use of needed_{head,tail}room values
to efficiently reserve buffer space for additional encapsulation headers,
such as VXLAN, Geneve, IPSec, etc. However, it is not currently possible
to query these values in a generic way.
Introduce ability to query the needed_{head,tail}room values of a network
device via rtnetlink, such that applications that may wish to use these
values can do so.
For example, Cilium agent iterates over present devices based on user config
(direct routing, vxlan, geneve, wireguard etc.) and in future will configure
netkit in order to expose the needed_{head,tail}room into K8s pods. See
b9ed315d3c4c ("netkit: Allow for configuring needed_{head,tail}room").

A slightly large change is found in qcom USB-audio offload stuff, but
this is a regression fix specific to this device, hence it should be
safe to apply at this late stage.
- Various small fixes for ASoC Cirrus, Realtek, lpass, Intel and
Qualcomm drivers
- ASoC SoundWire fixes
- A few TAS2781 HD-audio side-codec driver fixes
- A fix for Qualcomm USB-audio offload breakage
- Usual a few HD-audio quirks"

Currently, KF_RCU_PROTECTED only applies to iterator APIs and that too
in a convoluted fashion: the presence of this flag on the kfunc is used
to set MEM_RCU in iterator type, and the lack of RCU protection results
in an error only later, once next() or destroy() methods are invoked on
the iterator. While there is no bug, this is certainly a bit
unintuitive, and makes the enforcement of the flag iterator specific.
In the interest of making this flag useful for other upcoming kfuncs,
e.g. scx_bpf_cpu_curr() [0][1], add enforcement for invoking the kfunc
in an RCU critical section in general.
This would also mean that iterator APIs using KF_RCU_PROTECTED will
error out earlier, instead of throwing an error for lack of RCU CS
protection when next() or destroy() methods are invoked.
In addition to this, if the kfuncs tagged KF_RCU_PROTECTED return a
pointer value, ensure that this pointer value is only usable in an RCU
critical section. There might be edge cases where the return value is
special and doesn't need to imply MEM_RCU semantics, but in general, the
assumption should hold for the majority of kfuncs, and we can revisit
things if necessary later.
