e66d7a4f55 mm: convert FPB_IGNORE_* into FPB_RESPECT_*
Patch series "mm: folio_pte_batch() improvements", v2.

Ever since we added folio_pte_batch() for fork() + munmap() purposes, a
lot more users appeared (and more are being proposed), and more
functionality was added.

Most of the users only need basic functionality, and could benefit from a
non-inlined version.

So let's clean up folio_pte_batch() and split it into a basic
folio_pte_batch() (no flags) and a more advanced folio_pte_batch_ext(). 
Using either variant will now look much cleaner.

This series will likely conflict with some changes in some (old+new)
folio_pte_batch() users, but conflicts should be trivial to resolve.


This patch (of 4):

Respecting these PTE bits is the exception, so let's invert the meaning.

With this change, most callers don't have to pass any flags.  This is a
preparation for splitting folio_pte_batch() into a non-inlined variant
that doesn't consume any flags.

Long-term, we want folio_pte_batch() to probably ignore most common PTE
bits (e.g., write/dirty/young/soft-dirty) that are not relevant for most
page table walkers: uffd-wp and protnone might be bits to consider in the
future.  Only walkers that care about them can opt-in to respect them.

No functional change intended.

7765794810 mm/migrate: remove the -EEXIST conversion for move_pages()
The -EEXIST conversion is introduced in commit 65462462ff ("mm/gup:
follow_pfn_pte(): -EEXIST cleanup"), since follow_page() may call
follow_pfn_pte() which may return -EEXIST.

But after commit 7dff875c94 ("mm/migrate: convert
add_page_for_migration() from follow_page() to folio_walk"), it use
folio_walk instead.  This limit the error code and won't return -EEXIST.

Remove the error code conversion here.

e000df9ff1 mm/damon/sysfs: don't hold kdamond_lock in before_terminate()
damon_sysfs_before_terminate() is a DAMON callback that is executed from
the kdamond's context.  Hence it is safe to access DAMON context internal
data.  But the function is unnecessarily holding kdamond_lock of the

DAMON sample module, mtier has its name 'mtier'.  It could conflict with

Note that this could break users if they depend on the old name.  But it

e89d5bf3a4 mm: fault in complete folios instead of individual pages for tmpfs
After commit acd7ccb284 ("mm: shmem: add large folio support for
tmpfs"), tmpfs can also support large folio allocation (not just PMD-sized
large folios).

However, when accessing tmpfs via mmap(), although tmpfs supports large
folios, we still establish mappings at the base page granularity, which is
unreasonable.

We can map multiple consecutive pages of tmpfs folios at once according to
the size of the large folio.  On one hand, this can reduce the overhead of
page faults; on the other hand, it can leverage hardware architecture
optimizations to reduce TLB misses, such as contiguous PTEs on the ARM
architecture.

Moreover, tmpfs mount will use the 'huge=' option to control large folio
allocation explicitly.  So it can be understood that the process's RSS
statistics might increase, and I think this will not cause any obvious
effects for users.

Performance test:
I created a 1G tmpfs file, populated with 64K large folios, and write-accessed it
sequentially via mmap(). I observed a significant performance improvement:

Before the patch:
real	0m0.158s
user	0m0.008s
sys	0m0.150s

After the patch:
real	0m0.021s
user	0m0.004s
sys	0m0.017s

cc84ef3b88 rust: bits: add support for bits/genmask macros
In light of bindgen being unable to generate bindings for macros, and
owing to the widespread use of these macros in drivers, manually define
the bit and genmask C macros in Rust.

The *_checked version of the functions provide runtime checking while
the const version performs compile-time assertions on the arguments via
the build_assert!() macro.

c77f85b347 rust: list: remove OFFSET constants
Replace `ListLinksSelfPtr::LIST_LINKS_SELF_PTR_OFFSET` with `unsafe fn
raw_get_self_ptr` which returns a pointer to the field rather than
requiring the caller to do pointer arithmetic.

Implement `HasListLinks::raw_get_list_links` in `impl_has_list_links!`,
narrowing the interface of `HasListLinks` and replacing pointer
arithmetic with `container_of!`.

Modify `impl_list_item` to also invoke `impl_has_list_links!` or
`impl_has_list_links_self_ptr!`. This is necessary to allow
`impl_list_item` to see more of the tokens used by
`impl_has_list_links{,_self_ptr}!`.

A similar API change was discussed on the hrtimer series[1].

b5e8acc14d tracing: Add down_write(trace_event_sem) when adding trace event
When a module is loaded, it adds trace events defined by the module. It
may also need to modify the modules trace printk formats to replace enum
names with their values.

If two modules are loaded at the same time, the adding of the event to the
ftrace_events list can corrupt the walking of the list in the code that is
modifying the printk format strings and crash the kernel.

The addition of the event should take the trace_event_sem for write while
it adds the new event.

Also add a lockdep_assert_held() on that semaphore in
__trace_add_event_dirs() as it iterates the list.

d29591d5b5 wifi: ath12k: Advertise encapsulation/decapsulation offload support to mac80211
Currently, the mac80211 layer handles construction and parsing
of 802.11 headers during packet transmission and reception.
Offloading encapsulation and decapsulation to hardware can
significantly enhance performance. Check the service bit to determine
if the firmware supports Ethernet offload. If supported, advertise the
capability to mac80211 to bypass software-based 802.11 header
processing.

981050b918 wifi: ath12k: Fix TX status reporting to mac80211 when offload is enabled
Currently, the ath12k driver supports only the native Wi-Fi
frame format. In this mode, the ieee80211_tx_status() function
works correctly to report transmission status to mac80211, as
it retrieves station information using sta_info_get_by_addrs().

However, this method is not applicable for Ethernet-converted
packets, since sta_info_get_by_addrs() cannot extract station
information from such formats.

Retrieve station information using ath12k_peer_find_by_id() to
support all frame formats, including native Wi-Fi, raw, and Ethernet.
Report transmission status using ieee80211_tx_status_ext(), and
include rate information as part of the datapath TX status report.

646faf36d7 cgroup: Add compatibility option for content of /proc/cgroups
/proc/cgroups lists only v1 controllers by default, however, this is
only enforced since the commit af000ce852 ("cgroup: Do not report
unavailable v1 controllers in /proc/cgroups") and there is software in
the wild that uses content of /proc/cgroups to decide on availability of
v2 (sic) controllers.

Add a boottime param that can bring back the previous behavior for
setups where the check in the software cannot be changed and it causes
e.g. unintended OOMs.

Also, this patch takes out cgrp_v1_visible from cgroup1_subsys_absent()
guard since it's only important to check which hierarchy (v1 vs v2) the
subsys is attached to. This has no effect on the printed message but
the code is cleaner since cgrp_v1_visible is really about mounted
hierarchies, not the content of /proc/cgroups.

192c8e9a13 wifi: ath12k: Fix the handling of TX packets in Ethernet mode
Currently, in the transmit (TX) direction, EAPOL, QoS NULL,
and multicast frames are sent in native Wi-Fi (802.11) format.
However, when the virtual interface is configured in Ethernet
mode, transmission fails for packets enqueued in native Wi-fi format.

To address this issue, the firmware should be instructed to
treat these packets as RAW type packets, ensuring proper
handling even when the interface operates in Ethernet mode.

The test for "if (!desc_data)" does not work correctly because the list
iterator in a list_for_each_entry() loop is always non-NULL. If we don't
exit via a break, then it points to invalid memory.  Instead, use a tmp
variable for the list iterator and only set the "desc_data" when we have
found a match.
