Provide a direct request polling will for drivers. The interface does
not require a bio, and can skip the overhead associated with polling
those. The biggest gain from skipping the relatively expensive xarray
lookup unnecessary when you already have the request.
With this, the simple rq/qc conversion functions have only one caller
each, so open code this and remove the helpers.

Some servers may return error codes from REQ_GET_DFS_REFERRAL requests

non-DFS mounts when the client can't get the initial DFS referral of
@ctx->UNC in dfs_mount_share().

When having two DFS root mounts that are connected to same namespace,
same mount options but different prefix paths, we can't really use the
shared @server->origin_fullpath when chasing DFS links in them.
Move the origin_fullpath field to cifs_tcon structure so when having
shared DFS root mounts with different prefix paths, and we need to
chase any DFS links, dfs_get_automount_devname() will pick up the
correct full path out of the @tcon that will be used for the new
mount.
Before patch
mount.cifs //dom/dfs/dir /mnt/1 -o ...
mount.cifs //dom/dfs /mnt/2 -o ...
# shared server, ses, tcon
# server: origin_fullpath=//dom/dfs/dir
# @server->origin_fullpath + '/dir/link1'

Pull regmap updates from Mark Brown:
"Another busy release for regmap with the second half of the maple tree
register cache implementation, there's some smaller optimisations that
could be done but this should now be able to replace the rbtree cache
for most devices.
We also had a followup from Aidan MacDonald's refactoring of some of
the regmap-irq interfaces, the conversion is complete so the old
interfaces are removed. This means that even with the new features for
the maple tree cache we'd have a nice negative diffstat were it not
for the addition of a bunch more KUnit coverage.
There's one GPIO patch in here, it was a dependency for a cleanup of
an API in the regmap-irq code for which the gpio-104-dio-48e driver
was the only user.
Highlights:
- The maple tree cache can now load in default values more
efficiently, and is capabale of syncing multiple registers
in a single write during cache sync
- More KUnit coverage, including some coverage for raw I/O
and a dummy RAM backed cache to support it
- Removal of several old interfaces in regmap-irq now all
users have been modernised"

The memory encryption initialization logic was moved from init/main.c
into arch_cpu_finalize_init() in commit 439e17576eb4 ("init, x86: Move
mem_encrypt_init() into arch_cpu_finalize_init()"), but a stale
declaration for the init function was left in <linux/init.h>.
And didn't cause any problems if you had X86_MEM_ENCRYPT enabled, which
apparently everybody involved did have. See also commit 0a9567ac5e6a
("x86/mem_encrypt: Unbreak the AMD_MEM_ENCRYPT=n build") in this whole
sad saga of conflicting declarations for different situations.

Commit ca5e863233e8 ("mm/gup: remove vmas parameter from
get_user_pages_remote()") removed the vma argument from GUP handling,
and instead added a helper function (get_user_page_vma_remote()) that
looks it up separately using 'vma_lookup()'. And then converted
existing users that needed a vma to use the helper instead.
However, the helper function intentionally acts exactly like the old
get_user_pages_remote() did, and only fills in 'vma' on successful page
lookup. Fine so far.
However, __access_remote_vm() wants the vma even for the unsuccessful
case, and used to do a
vma = vma_lookup(mm, addr);
explicitly to look it up when the get_user_page() failed.
However, that conversion commit incorrectly removed that vma lookup,
thinking that get_user_page_vma_remote() would have done it. Not so.
So add the vma_lookup() back in.

io_uring offloads task_work for cancelation purposes when the task is
exiting. This is conceptually fine, but we should be nicer and actually
wait for that work to complete before returning.
Add an argument to io_fallback_tw() telling it to flush the deferred
work when it's all queued up, and have it flush a ctx behind whenever
the ctx changes.

Handle trailing and leading separators when parsing UNC and prefix

smb3_fs_context::source.
This fixes the following cases
$ mount //srv/share// /mnt/1 -o ...
$ cat /mnt/1/d0/f0
cat: /mnt/1/d0/f0: Invalid argument
The -EINVAL was returned because the client sent SMB2_CREATE "\\d0\f0"
rather than SMB2_CREATE "\d0\f0".
$ mount //srv//share /mnt/1 -o ...
mount: Invalid argument
The -EINVAL was returned correctly although the client only realised
it after sending a couple of bad requests rather than bailing out
earlier when parsing mount options.

All the server credits and in-flight info is protected by req_lock.
Once the req_lock is held, and we've determined that we have enough
credits to continue, this lock cannot be dropped till we've made the
changes to credits and in-flight count.
However, we used to drop the lock in order to avoid deadlock with
the recent srv_lock. This could cause the checks already made to be
invalidated.
Fixed it by moving the server status check to before locking req_lock.

If mas_store_gfp() in the gather loop failed, the 'error' variable that
ultimately gets returned was not being set. In many cases, its original
value of -ENOMEM was still in place, and that was fine. But if VMAs had
been split at the start or end of the range, then 'error' could be zero.
Change to the 'error = foo(); if (error) goto …' idiom to fix the bug.
Also clean up a later case which avoided the same bug by *explicitly*
setting error = -ENOMEM right before calling the function that might
return -ENOMEM.
In a final cosmetic change, move the 'Point of no return' comment to
*after* the goto. That's been in the wrong place since the preallocation
was removed, and this new error path was added.

Pull hardening updates from Kees Cook:
"There are three areas of note:
A bunch of strlcpy()->strscpy() conversions ended up living in my tree
since they were either Acked by maintainers for me to carry, or got
ignored for multiple weeks (and were trivial changes).
The compiler option '-fstrict-flex-arrays=3' has been enabled
globally, and has been in -next for the entire devel cycle. This
changes compiler diagnostics (though mainly just -Warray-bounds which
is disabled) and potential UBSAN_BOUNDS and FORTIFY _warning_
coverage. In other words, there are no new restrictions, just
potentially new warnings. Any new FORTIFY warnings we've seen have
been fixed (usually in their respective subsystem trees). For more
details, see commit df8fc4e934c12b.
The under-development compiler attribute __counted_by has been added
so that we can start annotating flexible array members with their
associated structure member that tracks the count of flexible array
elements at run-time. It is possible (likely?) that the exact syntax
of the attribute will change before it is finalized, but GCC and Clang
are working together to sort it out. Any changes can be made to the
macro while we continue to add annotations.
As an example of that last case, I have a treewide commit waiting with
such annotations found via Coccinelle:
https://git.kernel.org/linus/adc5b3cb48a049563dc673f348eab7b6beba8a9b
Also see commit dd06e72e68bcb4 for more details.
Summary:
- Fix KMSAN vs FORTIFY in strlcpy/strlcat (Alexander Potapenko)
- Convert strreplace() to return string start (Andy Shevchenko)
- Flexible array conversions (Arnd Bergmann, Wyes Karny, Kees Cook)
- Add missing function prototypes seen with W=1 (Arnd Bergmann)
- Fix strscpy() kerndoc typo (Arne Welzel)
- Replace strlcpy() with strscpy() across many subsystems which were
either Acked by respective maintainers or were trivial changes that

- Remove unneeded cc-option test for UBSAN_TRAP (Nick Desaulniers)
- Add KUnit tests for strcat()-family

- Improve checkpatch to check for strcpy, strncpy, and fake flex

- A SafeSetID patch to correct what appears to be a cut-n-paste typo in
the code causing a UID to be printed where a GID was desired.
This is coming via the LSM tree because we haven't been able to get a
response from the SafeSetID maintainer (Micah Morton) in several
months. Hopefully we are able to get in touch with Micah, but until
we do I'm going to pick them up in the LSM tree.
- A small fix to the reiserfs LSM xattr code.
We're continuing to work through some issues with the reiserfs code
as we try to fixup the LSM xattr handling, but in the process we're
uncovering some ugly problems in reiserfs and we may just end up
removing the LSM xattr support in reiserfs prior to reiserfs'
removal.
For better or worse, this shouldn't impact any of the reiserfs users,
as we discovered that LSM xattrs on reiserfs were completely broken,
meaning no one is currently using the combo of reiserfs and a file
labeling LSM.
- A tweak to how the cap_user_data_t struct/typedef is declared in the
header file to appease the Sparse gods.
- In the process of trying to sort out the SafeSetID lost-maintainer
problem I realized that I needed to update the labeled networking
entry to "Supported".

Pull ordered workqueue creation updates from Tejun Heo:
"For historical reasons, unbound workqueues with max concurrency limit
of 1 are considered ordered, even though the concurrency limit hasn't
been system-wide for a long time.
This creates ambiguity around whether ordered execution is actually
required for correctness, which was actually confusing for e.g. btrfs
(btrfs updates are being routed through the btrfs tree).
There aren't that many users in the tree which use the combination and
there are pending improvements to unbound workqueue affinity handling
which will make inadvertent use of ordered workqueue a bigger loss.
This clarifies the situation for most of them by updating the ones
which require ordered execution to use alloc_ordered_workqueue().
There are some conversions being routed through subsystem-specific
trees and likely a few stragglers. Once they're all converted,
workqueue can trigger a warning on unbound + @max_active==1 usages and
eventually drop the implicit ordered behavior"

- Add support for a new 'non CCA clear key token' with ECC clear keys
supported: ECC P256, ECC P384, ECC P521, ECC ED25519 and ECC ED448.
This makes it possible to derive a protected key from the ECC clear
key input via PKEY_KBLOB2PROTK3 ioctl, while currently the only way
to derive is via PCKMO instruction
- The s390 PMU of PAI crypto and extension 1 NNPA counters use atomic_t
for reference counting. Replace this with the proper data type
refcount_t
- Select ARCH_SUPPORTS_INT128, but limit this to clang for now, since
gcc generates inefficient code, which may lead to stack overflows
- Replace one-element array with flexible-array member in struct
vfio_ccw_parent and refactor the rest of the code accordingly. Also,
prefer struct_size() over sizeof() open- coded versions
- Introduce OS_INFO_FLAGS_ENTRY pointing to a flags field and
OS_INFO_FLAG_REIPL_CLEAR flag that informs a dumper whether the
system memory should be cleared or not once dumped
- Fix a hang when a user attempts to remove a VFIO-AP mediated device
attached to a guest: add VFIO_DEVICE_GET_IRQ_INFO and
VFIO_DEVICE_SET_IRQS IOCTLs and wire up the VFIO bus driver callback
to request a release of the device
- Fix calculation for R_390_GOTENT relocations for modules
- Allow any user space process with CAP_PERFMON capability read and
display the CPU Measurement facility counter sets
- Rework large statically-defined per-CPU cpu_cf_events data structure
and replace it with dynamically allocated structures created when a
perf_event_open() system call is invoked or /dev/hwctr device is
accessed

This reverts commit 6ebe94baa2b9ddf3ccbb7f94df6ab26234532734.
The patch "nios2: Convert __pte_free_tlb() to use ptdescs" was supposed
to go together with a patchset that Vishal Moola had planned taking it
through the mm tree. By just having this patch, all NIOS2 builds are
broken.
