The SoftiWARP Kconfig is missing "select" for CRYPTO and CRYPTO_CRC32C.
In addition, it improperly "depends on" LIBCRC32C, this should be a
"select", similar to net/sctp and others. As a dependency, SIW fails

device_register() always calls device_initialize() so calling device_del()
is safe even if device_register() fails. Implement the following advice
from the comment block above device_register(): "NOTE: _Never_ directly free
@dev after calling this function, even if it returned an error! Always use
put_device() to give up the reference initialized in this function instead."
Keep the kfree() call in the error path since srp_release_dev() does not
free the host.

According to the ib spec:
If the CI supports the Base Memory Management Extensions defined in this
specification, the L_Key format must consist of:
24 bit index in the most significant bits of the R_Key, and
8 bit key in the least significant bits of the R_Key
Through a successful Allocate L_Key verb invocation, the CI must let the
consumer own the key portion of the returned R_Key
Therefore, when creating a mkey using DEVX, the consumer is allowed to
change the key part. The kernel should compare only the index part of a
R_Key to determine equality with another R_Key.
Adding capability in order not to break backward compatibility.

Merge tag 'powerpc-6.0-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc fixes from Michael Ellerman:
- Ensure we never emit lwarx with EH=1 on 32-bit, because some 32-bit
CPUs trap on it rather than ignoring it as they should.
- Fix ftrace when building with clang, which was broken by some
refactoring.
- A couple of other minor fixes.
Thanks to Christophe Leroy, Naveen N. Rao, Nick Desaulniers, Ondrej
Mosnacek, Pali Rohár, Russell Currey, and Segher Boessenkool.

Merge tag '5.20-rc-smb3-client-fixes-part2' of git://git.samba.org/sfrench/cifs-2.6
Pull more cifs updates from Steve French:
- two fixes for stable, one for a lock length miscalculation, and
another fixes a lease break timeout bug
- improvement to handle leases, allows the close timeout to be
configured more safely
- five restructuring/cleanup patches
* tag '5.20-rc-smb3-client-fixes-part2' of git://git.samba.org/sfrench/cifs-2.6:
cifs: Do not access tcon->cfids->cfid directly from is_path_accessible
cifs: Add constructor/destructors for tcon->cfid
SMB3: fix lease break timeout when multiple deferred close handles for the same file.
smb3: allow deferred close timeout to be configurable
cifs: Do not use tcon->cfid directly, use the cfid we get from open_cached_dir
cifs: Move cached-dir functions into a separate file
cifs: Remove {cifs,nfs}_fscache_release_page()
cifs: fix lock length calculation
Enable multipage folio support for the afs filesystem.
Support has already been implemented in netfslib, fscache and cachefiles
and in most of afs, but I've waited for Matthew Wilcox's latest folio
changes.
Note that it does require a change to afs_write_begin() to return the
correct subpage. This is a "temporary" change as we're working on
getting rid of the need for ->write_begin() and ->write_end()
completely, at least as far as network filesystems are concerned - but
it doesn't prevent afs from making use of the capability.
