ASoC: Fixes for v6.9

A relatively large set of fixes here, the biggest piece of it is a
series correcting some problems with the delay reporting for Intel SOF
cards but there's a bunch of other things. Everything here is driver
specific except for a fix in the core for an issue with sign extension
handling volume controls.

Merge branch 'linus' into x86/boot, to resolve conflict

There's a new conflict with Linus's upstream tree, because
in the following merge conflict resolution in <asm/coco.h>:

38b334fc767e Merge tag 'x86_sev_for_v6.9_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Linus has resolved the conflicting placement of 'cc_mask' better
than the original commit:

1c811d403afd x86/sev: Fix position dependent variable references in startup code

... which was also done by an internal merge resolution:

2e5fc4786b7a Merge branch 'x86/sev' into x86/boot, to resolve conflicts and to pick up dependent tree

But Linus is right in 38b334fc767e, the 'cc_mask' declaration is sufficient
within the #ifdef CONFIG_ARCH_HAS_CC_PLATFORM block.

So instead of forcing Linus to do the same resolution again, merge in Linus's
tree and follow his conflict resolution.

Merge tag 'vfs-6.9.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull misc vfs updates from Christian Brauner:
"Misc features, cleanups, and fixes for vfs and individual filesystems.

Features:

- Support idmapped mounts for hugetlbfs.

- Add RWF_NOAPPEND flag for pwritev2(). This allows us to fix a bug
where the passed offset is ignored if the file is O_APPEND. The new
flag allows a caller to enforce that the offset is honored to
conform to posix even if the file was opened in append mode.

- Move i_mmap_rwsem in struct address_space to avoid false sharing
between i_mmap and i_mmap_rwsem.

- Convert efs, qnx4, and coda to use the new mount api.

- Add a generic is_dot_dotdot() helper that's used by various
filesystems and the VFS code instead of open-coding it multiple
times.

- Recently we've added stable offsets which allows stable ordering
when iterating directories exported through NFS on e.g., tmpfs
filesystems. Originally an xarray was used for the offset map but
that caused slab fragmentation issues over time. This switches the
offset map to the maple tree which has a dense mode that handles
this scenario a lot better. Includes tests.

- Finally merge the case-insensitive improvement series Gabriel has
been working on for a long time. This cleanly propagates case
insensitive operations through ->s_d_op which in turn allows us to
remove the quite ugly generic_set_encrypted_ci_d_ops() operations.
It also improves performance by trying a case-sensitive comparison
first and then fallback to case-insensitive lookup if that fails.
This also fixes a bug where overlayfs would be able to be mounted
over a case insensitive directory which would lead to all sort of
odd behaviors.

Cleanups:

- Make file_dentry() a simple accessor now that ->d_real() is
simplified because of the backing file work we did the last two
cycles.

- Use the dedicated file_mnt_idmap helper in ntfs3.

- Use smp_load_acquire/store_release() in the i_size_read/write
helpers and thus remove the hack to handle i_size reads in the
filemap code.

- The SLAB_MEM_SPREAD is a nop now. Remove it from various places in
fs/

- It's no longer necessary to perform a second built-in initramfs
unpack call because we retain the contents of the previous
extraction. Remove it.

- Now that we have removed various allocators kfree_rcu() always
works with kmem caches and kmalloc(). So simplify various places
that only use an rcu callback in order to handle the kmem cache
case.

- Convert the pipe code to use a lockdep comparison function instead
of open-coding the nesting making lockdep validation easier.

- Move code into fs-writeback.c that was located in a header but can
be made static as it's only used in that one file.

- Rewrite the alignment checking iterators for iovec and bvec to be
easier to read, and also significantly more compact in terms of
generated code. This saves 270 bytes of text on x86-64 (with
clang-18) and 224 bytes on arm64 (with gcc-13). In profiles it also
saves a bit of time for the same workload.

- Switch various places to use KMEM_CACHE instead of
kmem_cache_create().

- Use inode_set_ctime_to_ts() in inode_set_ctime_current()

- Use kzalloc() in name_to_handle_at() to avoid kernel infoleak.

- Various smaller cleanups for eventfds.

Fixes:

- Fix various comments and typos, and unneeded initializations.

- Fix stack allocation hack for clang in the select code.

- Improve dump_mapping() debug code on a best-effort basis.

- Fix build errors in various selftests.

- Avoid wrap-around instrumentation in various places.

- Don't allow user namespaces without an idmapping to be used for
idmapped mounts.

- Fix sysv sb_read() call.

- Fix fallback implementation of the get_name() export operation"

removed, and absent (as per FSCRYPT_KEY_STATUS_* used in the UAPI).

fscrypt: track master key presence separately from secret

Master keys can be in one of three states: present, incompletely
removed, and absent (as per FSCRYPT_KEY_STATUS_* used in the UAPI).
Currently, the way that "present" is distinguished from "incompletely
removed" internally is by whether ->mk_secret exists or not.

With extent-based encryption, it will be necessary to allow per-extent
keys to be derived while the master key is incompletely removed, so that
I/O on open files will reliably continue working after removal of the
key has been initiated. (We could allow I/O to sometimes fail in that
case, but that seems problematic for reasons such as writes getting
silently thrown away and diverging from the existing fscrypt semantics.)
Therefore, when the filesystem is using extent-based encryption,
->mk_secret can't be wiped when the key becomes incompletely removed.

As a prerequisite for doing that, this patch makes the "present" state
be tracked using a new field, ->mk_present. No behavior is changed yet.

The basic idea here is borrowed from Josef Bacik's patch
"fscrypt: use a flag to indicate that the master key is being evicted"
(https://lore.kernel.org/r/e86c16dddc049ff065f877d793ad773e4c6bfad9.1696970227.git.josef@toxicpanda.com).
I reimplemented it using a "present" bool instead of an "evicted" flag,
fixed a couple bugs, and tried to update everything to be consistent.

Note: I considered adding a ->mk_status field instead, holding one of
FSCRYPT_KEY_STATUS_*. At first that seemed nice, but it ended up being
more complex (despite simplifying FS_IOC_GET_ENCRYPTION_KEY_STATUS),
since it would have introduced redundancy and had weird locking rules.
