03acb9ccec keys: Remove unused extern declarations 
Since commit b2a4df200d ("KEYS: Expand the capacity of a keyring")
iterate_over_keyring() is never used, so can be removed.

And commit b5f545c880 ("[PATCH] keys: Permit running process to instantiate keys")
left behind keyring_search_instkey().

c745cd1718 KEYS: trusted: tee: Refactor register SHM usage 
The OP-TEE driver using the old SMC based ABI permits overlapping shared
buffers, but with the new FF-A based ABI each physical page may only
be registered once.

As the key and blob buffer are allocated adjancently, there is no need
for redundant register shared memory invocation. Also, it is incompatibile
with FF-A based ABI limitation. So refactor register shared memory
implementation to use only single invocation to register both key and blob
buffers.

eb96e22193 btrfs: fix unwritten extent buffer after snapshotting a new subvolume 
When creating a snapshot of a subvolume that was created in the current
transaction, we can end up not persisting a dirty extent buffer that is
referenced by the snapshot, resulting in IO errors due to checksum failures
when trying to read the extent buffer later from disk. A sequence of steps
that leads to this is the following:

1) At ioctl.c:create_subvol() we allocate an extent buffer, with logical
   address 36007936, for the leaf/root of a new subvolume that has an ID
   of 291. We mark the extent buffer as dirty, and at this point the
   subvolume tree has a single node/leaf which is also its root (level 0);

2) We no longer commit the transaction used to create the subvolume at
   create_subvol(). We used to, but that was recently removed in
   commit 1b53e51a4a ("btrfs: don't commit transaction for every subvol
   create");

3) The transaction used to create the subvolume has an ID of 33, so the
   extent buffer 36007936 has a generation of 33;

4) Several updates happen to subvolume 291 during transaction 33, several
   files created and its tree height changes from 0 to 1, so we end up with
   a new root at level 1 and the extent buffer 36007936 is now a leaf of
   that new root node, which is extent buffer 36048896.

   The commit root remains as 36007936, since we are still at transaction
   33;

5) Creation of a snapshot of subvolume 291, with an ID of 292, starts at
   ioctl.c:create_snapshot(). This triggers a commit of transaction 33 and
   we end up at transaction.c:create_pending_snapshot(), in the critical
   section of a transaction commit.

   There we COW the root of subvolume 291, which is extent buffer 36048896.
   The COW operation returns extent buffer 36048896, since there's no need
   to COW because the extent buffer was created in this transaction and it
   was not written yet.

   The we call btrfs_copy_root() against the root node 36048896. During
   this operation we allocate a new extent buffer to turn into the root
   node of the snapshot, copy the contents of the root node 36048896 into
   this snapshot root extent buffer, set the owner to 292 (the ID of the
   snapshot), etc, and then we call btrfs_inc_ref(). This will create a
   delayed reference for each leaf pointed by the root node with a
   reference root of 292 - this includes a reference for the leaf
   36007936.

   After that we set the bit BTRFS_ROOT_FORCE_COW in the root's state.

   Then we call btrfs_insert_dir_item(), to create the directory entry in
   in the tree of subvolume 291 that points to the snapshot. This ends up
   needing to modify leaf 36007936 to insert the respective directory
   items. Because the bit BTRFS_ROOT_FORCE_COW is set for the root's state,
   we need to COW the leaf. We end up at btrfs_force_cow_block() and then
   at update_ref_for_cow().

   At update_ref_for_cow() we call btrfs_block_can_be_shared() which
   returns false, despite the fact the leaf 36007936 is shared - the
   subvolume's root and the snapshot's root point to that leaf. The
   reason that it incorrectly returns false is because the commit root
   of the subvolume is extent buffer 36007936 - it was the initial root
   of the subvolume when we created it. So btrfs_block_can_be_shared()
   which has the following logic:

   int btrfs_block_can_be_shared(struct btrfs_root *root,
                                 struct extent_buffer *buf)
   {
       if (test_bit(BTRFS_ROOT_SHAREABLE, &root->state) &&
           buf != root->node && buf != root->commit_root &&
           (btrfs_header_generation(buf) <=
            btrfs_root_last_snapshot(&root->root_item) ||
            btrfs_header_flag(buf, BTRFS_HEADER_FLAG_RELOC)))
               return 1;

       return 0;
   }

   Returns false (0) since 'buf' (extent buffer 36007936) matches the
   root's commit root.

   As a result, at update_ref_for_cow(), we don't check for the number
   of references for extent buffer 36007936, we just assume it's not
   shared and therefore that it has only 1 reference, so we set the local
   variable 'refs' to 1.

   Later on, in the final if-else statement at update_ref_for_cow():

   static noinline int update_ref_for_cow(struct btrfs_trans_handle *trans,
                                          struct btrfs_root *root,
                                          struct extent_buffer *buf,
                                          struct extent_buffer *cow,
                                          int *last_ref)
   {
      (...)
      if (refs > 1) {
          (...)
      } else {
          (...)
          btrfs_clear_buffer_dirty(trans, buf);
          *last_ref = 1;
      }
   }

   So we mark the extent buffer 36007936 as not dirty, and as a result
   we don't write it to disk later in the transaction commit, despite the
   fact that the snapshot's root points to it.

   Attempting to access the leaf or dumping the tree for example shows
   that the extent buffer was not written:

   $ btrfs inspect-internal dump-tree -t 292 /dev/sdb
   btrfs-progs v6.2.2

   file data blocks allocated: 65978368

Fix this by updating btrfs_block_can_be_shared() to consider that an
extent buffer may be shared if it matches the commit root and if its
generation matches the current transaction's generation.

This can be reproduced with the following script:

   $ cat test.sh
   #!/bin/bash

   MNT=/mnt/sdi
   DEV=/dev/sdi

   # Use a filesystem with a 64K node size so that we have the same node
   # size on every machine regardless of its page size (on x86_64 default
   # node size is 16K due to the 4K page size, while on PPC it's 64K by
   # default). This way we can make sure we are able to create a btree for
   # the subvolume with a height of 2.
   mkfs.btrfs -f -n 64K $DEV
   mount $DEV $MNT

   btrfs subvolume create $MNT/subvol

   # Create a few empty files on the subvolume, this bumps its btree
   # height to 2 (root node at level 1 and 2 leaves).
   for ((i = 1; i <= 300; i++)); do
       echo -n > $MNT/subvol/file_$i
   done

   btrfs subvolume snapshot -r $MNT/subvol $MNT/subvol/snap

   umount $DEV

   btrfs check $DEV

Running it on a 6.5 kernel (or any 6.6-rc kernel at the moment):

   $ ./test.sh

9c5d00cb7b perf tools fixes for v6.6: 2nd batch 
- Fix regression in reading scale and unit files from sysfs for PMU
   events, so that we can use that info to pretty print instead of
   printing raw numbers:
 
   # perf stat -e power/energy-ram/,power/energy-gpu/ sleep 2
 
    Performance counter stats for 'system wide':
 
               1.64 Joules power/energy-ram/
               0.20 Joules power/energy-gpu/
 
        2.001228914 seconds time elapsed
   #
   # grep -m1 "model name" /proc/cpuinfo
   model name	: Intel(R) Core(TM) i7-8650U CPU @ 1.90GHz
   #
 
 - The small llvm.cpp file used to check if the llvm devel files are present was
   incorrectly deleted when removing the BPF event in 'perf trace', put it back
   as it is also used by tools/bpf/bpftool, that uses llvm routines to do
   disassembly of BPF object files.
 
 - Fix use of addr_location__exit() in dlfilter__object_code(), making sure that
   it is only used to pair a previous addr_location__init() call.

f617647154 In the raw NAND subsystem, the major fix prevents using cached reads 
with devices not supporting it. There was two bug reports about
 this. Aside, 3 drivers (pl353, arasan and marvell) could sometimes hide
 page program failures due to their their own program page helper not
 being fully compliant with the specification (many drivers use the
 default helpers shared by the core). Adding a missing check prevents
 these situation. Finally, the Qualcomm driver had a broken error path.
 
 In the SPI-NAND subsystem one Micron device used a wrong bitmak
 reporting possibly corrupted ECC status.
 
 Finally, the physmap-core got stripped from its map_rom fallback by
 mistake, this feature is added back.

50e782a86c efi/unaccepted: Fix soft lockups caused by parallel memory acceptance 
Michael reported soft lockups on a system that has unaccepted memory.
This occurs when a user attempts to allocate and accept memory on
multiple CPUs simultaneously.

The root cause of the issue is that memory acceptance is serialized with
a spinlock, allowing only one CPU to accept memory at a time. The other
CPUs spin and wait for their turn, leading to starvation and soft lockup
reports.

To address this, the code has been modified to release the spinlock
while accepting memory. This allows for parallel memory acceptance on
multiple CPUs.

A newly introduced "accepting_list" keeps track of which memory is
currently being accepted. This is necessary to prevent parallel
acceptance of the same memory block. If a collision occurs, the lock is
released and the process is retried.

Such collisions should rarely occur. The main path for memory acceptance
is the page allocator, which accepts memory in MAX_ORDER chunks. As long
as MAX_ORDER is equal to or larger than the unit_size, collisions will
never occur because the caller fully owns the memory block being
accepted.

Aside from the page allocator, only memblock and deferered_free_range()
accept memory, but this only happens during boot.

The code has been tested with unit_size == 128MiB to trigger collisions
and validate the retry codepath.

b022f0c7e4 tracing/kprobes: Return EADDRNOTAVAIL when func matches several symbols 
When a kprobe is attached to a function that's name is not unique (is
static and shares the name with other functions in the kernel), the
kprobe is attached to the first function it finds. This is a bug as the
function that it is attaching to is not necessarily the one that the
user wants to attach to.

Instead of blindly picking a function to attach to what is ambiguous,
error with EADDRNOTAVAIL to let the user know that this function is not
unique, and that the user must use another unique function with an
address offset to get to the function they want to attach to.

4fa008a2db tools build: Fix llvm feature detection, still used by bpftool 
When removing the BPF event for perf a feature test that checks if the
llvm devel files are availabe was removed but that is also used by
bpftool.

bpftool uses it to decide what kind of disassembly it will use: llvm or
binutils based.

Removing the tools/build/feature/test-llvm.cpp file made bpftool to
always fallback to binutils disassembly, even with the llvm devel files
installed, fix it by restoring just that small test-llvm.cpp test file.

Fixes: 56b11a2126 ("perf bpf: Remove support for embedding clang for compiling BPF events (-e foo.c)")

ce55c22ec8 Including fixes from bluetooth, netfilter, WiFi. 
Feels like an up-tick in regression fixes, mostly for older releases.
 The hfsc fix, tcp_disconnect() and Intel WWAN fixes stand out as fairly
 clear-cut user reported regressions. The mlx5 DMA bug was causing strife
 for 390x folks. The fixes themselves are not particularly scary, tho.
 No open investigations / outstanding reports at the time of writing.
 
 Current release - regressions:
 
  - eth: mlx5: perform DMA operations in the right locations,
    make devices usable on s390x, again
 
  - sched: sch_hfsc: upgrade 'rt' to 'sc' when it becomes a inner curve,
    previous fix of rejecting invalid config broke some scripts
 
  - rfkill: reduce data->mtx scope in rfkill_fop_open, avoid deadlock
 
  - revert "ethtool: Fix mod state of verbose no_mask bitset",
    needs more work
 
 Current release - new code bugs:
 
  - tcp: fix listen() warning with v4-mapped-v6 address
 
 Previous releases - regressions:
 
  - tcp: allow tcp_disconnect() again when threads are waiting,
    it was denied to plug a constant source of bugs but turns out
    .NET depends on it
 
  - eth: mlx5: fix double-free if buffer refill fails under OOM
 
  - revert "net: wwan: iosm: enable runtime pm support for 7560",
    it's causing regressions and the WWAN team at Intel disappeared
 
  - tcp: tsq: relax tcp_small_queue_check() when rtx queue contains
    a single skb, fix single-stream perf regression on some devices
 
 Previous releases - always broken:
 
  - Bluetooth:
    - fix issues in legacy BR/EDR PIN code pairing
    - correctly bounds check and pad HCI_MON_NEW_INDEX name
 
  - netfilter:
    - more fixes / follow ups for the large "commit protocol" rework,
      which went in as a fix to 6.5
    - fix null-derefs on netlink attrs which user may not pass in
 
  - tcp: fix excessive TLP and RACK timeouts from HZ rounding
    (bless Debian for keeping HZ=250 alive)
 
  - net: more strict VIRTIO_NET_HDR_GSO_UDP_L4 validation, prevent
    letting frankenstein UDP super-frames from getting into the stack
 
  - net: fix interface altnames when ifc moves to a new namespace
