bonding: add ns target multicast address to slave device
Commit 4598380f9c54 ("bonding: fix ns validation on backup slaves")
tried to resolve the issue where backup slaves couldn't be brought up when
receiving IPv6 Neighbor Solicitation (NS) messages. However, this fix only
worked for drivers that receive all multicast messages, such as the veth
interface.
For standard drivers, the NS multicast message is silently dropped because
the slave device is not a member of the NS target multicast group.
To address this, we need to make the slave device join the NS target
multicast group, ensuring it can receive these IPv6 NS messages to validate
the slave’s status properly.
There are three policies before joining the multicast group:
1. All settings must be under active-backup mode (alb and tlb do not support
arp_validate), with backup slaves and slaves supporting multicast.
2. We can add or remove multicast groups when arp_validate changes.
3. Other operations, such as enslaving, releasing, or setting NS targets,
need to be guarded by arp_validate.

Accessing `mr_table->mfc_cache_list` is protected by an RCU lock. In the

This is not a problem per see, since the RTNL lock is held here, so, it
is safe to iterate in the list without the RCU read lock, as suggested
by Eric.
To alleviate the concern, modify the code to use
list_for_each_entry_rcu() with the RTNL-held argument.
The annotation will raise an error only if RTNL or RCU read lock are
missing during iteration, signaling a legitimate problem, otherwise it
will avoid this false positive.
This will solve the IPv6 case as well, since ip6mr_rtm_dumproute() calls
this function as well.

drm/xe: handle flat ccs during hibernation on igpu
Starting from LNL, CCS has moved over to flat CCS model where there is
now dedicated memory reserved for storing compression state. On
platforms like LNL this reserved memory lives inside graphics stolen
memory, which is not treated like normal RAM and is therefore skipped by
the core kernel when creating the hibernation image. Currently if
something was compressed and we enter hibernation all the corresponding
CCS state is lost on such HW, resulting in corrupted memory. To fix this
evict user buffers from TT -> SYSTEM to ensure we take a snapshot of the
raw CCS state when entering hibernation, where upon resuming we can
restore the raw CCS state back when next validating the buffer. This has
been confirmed to fix display corruption on LNL when coming back from
hibernation.

drm/xe: improve hibernation on igpu
The GGTT looks to be stored inside stolen memory on igpu which is not
treated as normal RAM. The core kernel skips this memory range when
creating the hibernation image, therefore when coming back from
hibernation the GGTT programming is lost. This seems to cause issues
with broken resume where GuC FW fails to load:
Current GGTT users are kernel internal and tracked as pinned, so it
should be possible to hook into the existing save/restore logic that we
use for dgpu, where the actual evict is skipped but on restore we
importantly restore the GGTT programming. This has been confirmed to
fix hibernation on at least ADL and MTL, though likely all igpu
platforms are affected.
This also means we have a hole in our testing, where the existing s4
tests only really test the driver hooks, and don't go as far as actually
rebooting and restoring from the hibernation image and in turn powering
down RAM (and therefore losing the contents of stolen).

drm/panthor: Fix handling of partial GPU mapping of BOs
This commit fixes the bug in the handling of partial mapping of the
buffer objects to the GPU, which caused kernel warnings.
Panthor didn't correctly handle the case where the partial mapping
spanned multiple scatterlists and the mapping offset didn't point
to the 1st page of starting scatterlist. The offset variable was
not cleared after reaching the starting scatterlist.
Following warning messages were seen.

selftests: hugetlb_dio: fixup check for initial conditions to skip in the start

Reading free hugepages before the test was removed by commit 0268d4579901

mm/thp: fix deferred split queue not partially_mapped: fix
Though even more elusive than before, list_del corruption has still been
seen on THP's deferred split queue.
The idea in commit e66f3185fa04 was right, but its implementation wrong.
The context omitted an important comment just before the critical test:
"split_folio() removes folio from list on success." In ignoring that
comment, when a THP split succeeded, the code went on to release the
preceding safe folio, preserving instead an irrelevant (formerly head)
folio: which gives no safety because it's not on the list. Fix the logic.

mm/gup: avoid an unnecessary allocation call for FOLL_LONGTERM cases
commit 53ba78de064b ("mm/gup: introduce
check_and_migrate_movable_folios()") created a new constraint on the
pin_user_pages*() API family: a potentially large internal allocation must
now occur, for FOLL_LONGTERM cases.
A user-visible consequence has now appeared: user space can no longer pin
more than 2GB of memory anymore on x86_64. That's because, on a 4KB
PAGE_SIZE system, when user space tries to (indirectly, via a device
driver that calls pin_user_pages()) pin 2GB, this requires an allocation
of a folio pointers array of MAX_PAGE_ORDER size, which is the limit for
kmalloc().
In addition to the directly visible effect described above, there is also
the problem of adding an unnecessary allocation. The **pages array
argument has already been allocated, and there is no need for a redundant
**folios array allocation in this case.
Fix this by avoiding the new allocation entirely. This is done by
referring to either the original page[i] within **pages, or to the
associated folio. Thanks to David Hildenbrand for suggesting this
approach and for providing the initial implementation (which I've tested
and adjusted slightly) as well.

And while this alone would make a trivial fix, the H616 falls back to

As the A100 is now compatible with the D1 description, let the A100

LoongArch: Fix AP booting issue in VM mode
Native IPI is used for AP booting, because it is the booting interface
between OS and BIOS firmware. The paravirt IPI is only used inside OS,
and native IPI is necessary to boot AP.
When booting AP, we write the kernel entry address in the HW mailbox of
AP and send IPI interrupt to it. AP executes idle instruction and waits
for interrupts or SW events, then clears IPI interrupt and jumps to the
kernel entry from HW mailbox.
Between writing HW mailbox and sending IPI, AP can be woken up by SW
events and jumps to the kernel entry, so ACTION_BOOT_CPU IPI interrupt
will keep pending during AP booting. And native IPI interrupt handler
needs be registered so that it can clear pending native IPI, else there
will be endless interrupts during AP booting stage.
Here native IPI interrupt is initialized even if paravirt IPI is used.

Since CONFIG_4KB_4LEVEL is completely legal for CPUs with cpu_vabits <=
