Pull misc x86 updates from Borislav Petkov:
- The first part of a restructuring of AMD's representation of a
northbridge which is legacy now, and the creation of the new AMD node
concept which represents the Zen architecture of having a collection
of I/O devices within an SoC. Those nodes comprise the so-called data
fabric on Zen.
This has at least one practical advantage of not having to add a PCI
ID each time a new data fabric PCI device releases. Eventually, the
lot more uniform provider of data fabric functionality amd_node.c
will be used by all the drivers which need it

A logic inversion in rseq_reset_rseq_cpu_node_id() causes the rseq
unregistration to fail when rseq_validate_ro_fields() succeeds rather

When enabling a pass-through port an interrupt might come before psmouse
driver binds to the pass-through port. However synaptics sub-driver
tries to access psmouse instance presumably associated with the
pass-through port to figure out if only 1 byte of response or entire
protocol packet needs to be forwarded to the pass-through port and may
crash if psmouse instance has not been attached to the port yet.
Fix the crash by introducing open() and close() methods for the port and
check if the port is open before trying to access psmouse instance.
Because psmouse calls serio_open() only after attaching psmouse instance
to serio port instance this prevents the potential crash.

Microsoft defined Meta+Shift+F23 as the Copilot shortcut instead of a
dedicated keycode, and multiple vendors have their keyboards emit this
sequence in response to users pressing a dedicated "Copilot" key.
Unfortunately the default keymap table in atkbd does not map scancode
0x6e (F23) and so the key combination does not work even if userspace
is ready to handle it.
Because this behavior is common between multiple vendors and the
scancode is currently unused map 0x6e to keycode 193 (KEY_F23) so that
key sequence is generated properly.

We are missing netif_napi_del() and am65_cpsw_nuss_free_tx/rx_chns()
in error path when am65_cpsw_nuss_init_tx/rx_chns() is used anywhere
other than at probe(). i.e. am65_cpsw_nuss_update_tx_rx_chns and
am65_cpsw_nuss_resume()
As reported, in am65_cpsw_nuss_update_tx_rx_chns(),
if am65_cpsw_nuss_init_tx_chns() partially fails then
devm_add_action(dev, am65_cpsw_nuss_free_tx_chns,..) is added
but the cleanup via am65_cpsw_nuss_free_tx_chns() will not run.
Same issue exists for am65_cpsw_nuss_init_tx/rx_chns() failures
in am65_cpsw_nuss_resume() as well.
This would otherwise require more instances of devm_add/remove_action
and is clearly more of a distraction than any benefit.
So, drop devm_add/remove_action for am65_cpsw_nuss_free_tx/rx_chns()
and call am65_cpsw_nuss_free_tx/rx_chns() and netif_napi_del()
where required.

Pull bcachefs updates from Kent Overstreet:
"Lots of scalability work, another big on-disk format change. On-disk
format version goes from 1.13 to 1.20.
Like 6.11, this is another big and expensive automatic/required on
disk format upgrade. This is planned to be the last big on disk format
upgrade before the experimental label comes off. There will be one
more minor on disk format update for a few things that couldn't make
this release.
Headline improvements:
- Self healing work:
Allocator and reflink now run the exact same check/repair code that
fsck does at runtime, where applicable.
The long term goal here is to remove inconsistent() errors (that
cause us to go emergency read only) by lifting fsck code up to
normal runtime paths; we should only go emergency read-only if we
detect an inconsistency that was due to a runtime bug - or truly
catastrophic damage (corrupted btree roots/interior nodes).
- Reflink repair no longer deletes reflink pointers:
Instead we flip an error bit and log the error, and they can still
be deleted by file deletion. This means a temporary failure to find
an indirect extent (perhaps repaired later by btree node scan)
won't result in unnecessary data loss
- Improvements to rebalance data path option handling:
We can now correctly apply changed filesystem-level io path options
to pending rebalance work, and soon we'll be able to apply
file-level io path option changes to indirect extents
- Fix mount time regression that some users encountered post the 6.11
disk accounting rewrite.
Accounting keys were encoded little endian (typetag in the low
bits) - which didn't anticipate adding accounting keys for every
inode, which aren't stored in memory and we don't want to scan at
mount time.
- fsck time on large filesystems is improved by multiple orders of
magnitude. Previously, 100TB was about the practical max filesystem
size, where users were reporting fsck times of a day+. With the new
changes (which nearly eliminate backpointers fsck overhead), we
fsck'd a filesystem with 10PB of data in 1.5 hours.
The problematic fsck passes were walking every extent and checking
for missing backpointers, and walking every backpointer to check
for dangling backpointers. As we've been adding more and more
runtime self healing there was no reason to keep around the
backpointers -> extents pass; dangling backpointers are just
deleted, and we can do that when using them - thus, backpointers ->
extents is now only run in debug mode.
extents -> backpointers does need to exist, since missing
backpointers would mean we can't find data to move it (for e.g.
copygc, device evacuate, scrub). But the new on disk format version
makes possible a new strategy where we sum up backpointers within a
bucket and check it against the bucket sector counts, and then only
scan for missing backpointers if the counts are off (and then, only
for specific buckets).
Full list of on disk format changes:
- 1.14: backpointer_bucket_gen
Backpointers now have a field for the bucket generation number,
replacing the obsolete bucket_offset field. This is needed for the
new "sum up backpointers within a bucket" code, since backpointers
use the btree write buffer - meaning we will see stale reads, and
this runs online, with the filesystem in full rw mode.
- 1.15: disk_accounting_big_endian
As previously described, fix the endianness of accounting keys so
that accounting keys with the same typetag sort together, and
accounting read can skip types it's not interested in.
- 1.16: reflink_p_may_update_opts:
This version indicates that a new reflink pointer field is
understood and may be used; the field indicates whether the reflink
pointer has permissions to update IO path options (e.g.
compression, replicas) may be updated on the indirect extent it
points to.
This completes the rebalance/reflink data path option handling from
the 6.13 pull request.
- 1.17: inode_depth
Add a new inode field, bi_depth, to accelerate the
check_directory_structure fsck path, which checks for loops in the
filesystem heirarchy.
check_inodes and check_dirents check connectivity, so
check_directory_structure only has to check for loops - by walking
back up to the root from every directory.
But a path can't be a loop if it has a counter that increases
monotonically from root to leaf - adding a depth counter means that
we can check for loops with only local (parent -> child) checks. We
might need to occasionally renumber the depth field in fsck if
directories have been moved around, but then future fsck runs will
be much faster.
- 1.18: persistent_inode_cursors
Previously, the cursor used for inode allocation was only kept in
memory, which meant that users with large filesystems and lots of
files were reporting that the first create after mounting would
take awhile - since it had to scan from the start.
Inode allocation cursors are now persistent, and also include a
generation field (incremented on wraparound, which will only happen
if inode allocation is restricted to 32 bit inodes), so that we
don't have to leave inode_generation keys around after a delete.
The option for 32 bit inode numbers may now also be set on
individual directories, and non-32 bit inode allocations are
disallowed from allocating from the 32 bit part of the inode number
space.
- 1.19: autofix_errors
Runtime self healing is now the default.o
- 1.20: directory size (from Hongbo)
directory i_size is now meaningful, and not 0"

Pull btrfs updates from David Sterba:
"User visible changes, features:
- rebuilding of the free space tree at mount time is done in more
transactions, fix potential hangs when the transaction thread is
blocked due to large amount of block groups
- more read IO balancing strategies (experimental config), add two
new ways how to select a device for read if the profiles allow that
(all RAID1*), the current default selects the device by pid which
is good on average but less performant for single reader workloads
- select preferred device for all reads (namely for testing)
- round-robin, balance reads across devices relevant for the
requested IO range
- add encoded write ioctl support to io_uring (read was added in
6.12), basis for writing send stream using that instead of
syscalls, non-blocking mode is not yet implemented
- support FS_IOC_READ_VERITY_METADATA, applications can use the
metadata to do their own verification
- pass inode's i_write_hint to bios, for parity with other
filesystems, ioctls F_GET_RW_HINT/F_SET_RW_HINT
Core:
- in zoned mode: allow to directly reclaim a block group by simply
resetting it, then it can be reused and another block group does
not need to be allocated
- super block validation now also does more comprehensive sys array
validation, adding it to the points where superblock is validated
(post-read, pre-write)
- subpage mode fixes:
- fix double accounting of blocks due to some races
- improved or fixed error handling in a few cases (compression,
delalloc)
- raid stripe tree:
- fix various cases with extent range splitting or deleting
- implement hole punching to extent range
- reduce number of stripe tree lookups during bio submission
- more self-tests
- updated self-tests (delayed refs)
- error handling improvements
- cleanups, refactoring
- remove rest of backref caching infrastructure from relocation,
not needed anymore
- error message updates
- remove unnecessary calls when extent buffer was marked dirty
- unused parameter removal
- code moved to new files
Other code changes: add rb_find_add_cached() to the rb-tree API"

Let's register inet6_rtm_deladdr() with RTNL_FLAG_DOIT_PERNET and
hold rtnl_net_lock() before inet6_addr_del().
Now that inet6_addr_del() is always called under per-netns RTNL.

inet6_addr_add() and inet6_addr_modify() have the same code to validate
IPv6 lifetime that is done under RTNL.
Let's factorise it out to inet6_rtm_newaddr() so that we can validate
the lifetime without RTNL later.
Note that inet6_addr_add() is called from addrconf_add_ifaddr(), but the
lifetime is INFINITY_LIFE_TIME in the path, so expires and flags are 0.

We will convert inet6_rtm_newaddr() to per-netns RTNL.
Except for IFA_F_OPTIMISTIC, cfg.ifa_flags can be set before
__dev_get_by_index().
Let's move ifa_flags setup before __dev_get_by_index() so that
we can set ifa_flags without RTNL.
Also, now it's moved before tb[IFA_CACHEINFO] in preparing for
the next patch.

inet6_addr_add() is called from inet6_rtm_newaddr() and
addrconf_add_ifaddr().
inet6_addr_add() looks up dev by __dev_get_by_index(), but
it's already done in inet6_rtm_newaddr().
Let's move the 2nd lookup to addrconf_add_ifaddr() and pass
dev to inet6_addr_add().

addrconf_init() holds RTNL for blackhole_netdev, which is the global
device in init_net.
addrconf_cleanup() holds RTNL to clean up devices in init_net too.
Let's use rtnl_net_lock(&init_net) there.
