The keywrap (kw) algorithm has no in-tree user. It has never had an
in-tree user, and the patch that added it provided no justification for
its inclusion. Even use of it via AF_ALG is impossible, as it uses a
weird calling convention where part of the ciphertext is returned via
the IV buffer, which is not returned to userspace in AF_ALG.
It's also unclear whether any new code in the kernel that does key
wrapping would actually use this algorithm. It is controversial in the
cryptographic community due to having no clearly stated security goal,
no security proof, poor performance, and only a 64-bit auth tag. Later
work (https://eprint.iacr.org/2006/221) suggested that the goal is
deterministic authenticated encryption. But there are now more modern
algorithms for this, and this is not the same as key wrapping, for which
a regular AEAD such as AES-GCM usually can be (and is) used instead.
Therefore, remove this unused code.
There were several special cases for this algorithm in the self-tests,
due to its weird calling convention. Remove those too.

Remove the vmac64 template, as it has no known users. It also continues
to have longstanding bugs such as alignment violations (see
https://lore.kernel.org/r/20241226134847.6690-1-evepolonium@gmail.com/).
This code was added in 2009 by commit f1939f7c56 ("crypto: vmac - New
hash algorithm for intel_txt support"). Based on the mention of
intel_txt support in the commit title, it seems it was added as a
prerequisite for the contemporaneous patch
"intel_txt: add s3 userspace memory integrity verification"
(https://lore.kernel.org/r/4ABF2B50.6070106@intel.com/). In the design
proposed by that patch, when an Intel Trusted Execution Technology (TXT)
enabled system resumed from suspend, the "tboot" trusted executable
launched the Linux kernel without verifying userspace memory, and then
the Linux kernel used VMAC to verify userspace memory.
However, that patch was never merged, as reviewers had objected to the
design. It was later reworked into commit 4bd96a7a81 ("x86, tboot:
Add support for S3 memory integrity protection") which made tboot verify
the memory instead. Thus the VMAC support in Linux was never used.
No in-tree user has appeared since then, other than potentially the
usual components that allow specifying arbitrary hash algorithms by
name, namely AF_ALG and dm-integrity. However there are no indications
that VMAC is being used with these components. Debian Code Search and
web searches for "vmac64" (the actual algorithm name) do not return any
results other than the kernel itself, suggesting that it does not appear
in any other code or documentation. Explicitly grepping the source code
of the usual suspects (libell, iwd, cryptsetup) finds no matches either.
Before 2018, the vmac code was also completely broken due to using a
hardcoded nonce and the wrong endianness for the MAC. It was then fixed
by commit ed331adab3 ("crypto: vmac - add nonced version with big
endian digest") and commit 0917b87312 ("crypto: vmac - remove insecure
version with hardcoded nonce"). These were intentionally breaking
changes that changed all the computed MAC values as well as the
algorithm name ("vmac" to "vmac64"). No complaints were ever received
about these breaking changes, strongly suggesting the absence of users.
The reason I had put some effort into fixing this code in 2018 is
because it was used by an out-of-tree driver. But if it is still needed
in that particular out-of-tree driver, the code can be carried in that
driver instead. There is no need to carry it upstream.

Pull slab updates from Vlastimil Babka:
- SLAB deprecation:
Following the discussion at LSF/MM 2023 [1] and no objections, the
SLAB allocator is deprecated by renaming the config option (to make
its users notice) to CONFIG_SLAB_DEPRECATED with updated help text.
SLUB should be used instead. Existing defconfigs with CONFIG_SLAB are
also updated.
- SLAB_NO_MERGE kmem_cache flag (Jesper Dangaard Brouer):
There are (very limited) cases where kmem_cache merging is
undesirable, and existing ways to prevent it are hacky. Introduce a
new flag to do that cleanly and convert the existing hacky users.
Btrfs plans to use this for debug kernel builds (that use case is
always fine), networking for performance reasons (that should be very
rare).
- Replace the usage of weak PRNGs (David Keisar Schmidt):
In addition to using stronger RNGs for the security related features,
the code is a bit cleaner.
- Misc code cleanups (SeongJae Parki, Xiongwei Song, Zhen Lei, and
zhaoxinchao)

As discussed at LSF/MM [1] [2] and with no objections raised there,
deprecate the SLAB allocator. Rename the user-visible option so that
users with CONFIG_SLAB=y get a new prompt with explanation during make
oldconfig, while make olddefconfig will just switch to SLUB.
In all defconfigs with CONFIG_SLAB=y remove the line so those also
switch to SLUB. Regressions due to the switch should be reported to
linux-mm and slab maintainers.

This kernel configuration is basically enabling/disabling sr driver quirks
detection. While these quirks are for fairly rare devices (very old CD
burners, and a glucometer), the additional detection of these models is a
very minimal amount of code.
The logic behind the quirks is always built into the sr driver.
This also removes the config from all the defconfig files that are enabling
this already.
