Now that we've standardized on the byte-by-byte implementation of CRC32
as the only generic implementation (see previous commit for the
rationale), remove the code for the other implementations.
Tested with crc_kunit.

Make the following simplifications to the kconfig options for choosing
CRC implementations for CRC32 and CRC_T10DIF:
1. Make the option to disable the arch-optimized code be visible only
when CONFIG_EXPERT=y.
2. Make a single option control the inclusion of the arch-optimized code
for all enabled CRC variants.
3. Make CRC32_SARWATE (a.k.a. slice-by-1 or byte-by-byte) be the only
generic CRC32 implementation.
The result is there is now just one option, CRC_OPTIMIZATIONS, which is
default y and can be disabled only when CONFIG_EXPERT=y.
Rationale:
1. Enabling the arch-optimized code is nearly always the right choice.
However, people trying to build the tiniest kernel possible would
find some use in disabling it. Anything we add to CRC32 is de facto
unconditional, given that CRC32 gets selected by something in nearly
all kernels. And unfortunately enabling the arch CRC code does not
eliminate the need to build the generic CRC code into the kernel too,
due to CPU feature dependencies. The size of the arch CRC code will
also increase slightly over time as more CRC variants get added and
more implementations targeting different instruction set extensions
get added. Thus, it seems worthwhile to still provide an option to
disable it, but it should be considered an expert-level tweak.
2. Considering the use case described in (1), there doesn't seem to be
sufficient value in making the arch-optimized CRC code be
independently configurable for different CRC variants. Note also
that multiple variants were already grouped together, e.g.
CONFIG_CRC32 actually enables three different variants of CRC32.
3. The bit-by-bit implementation is uselessly slow, whereas slice-by-n
for n=4 and n=8 use tables that are inconveniently large: 4096 bytes
and 8192 bytes respectively, compared to 1024 bytes for n=1. Higher
n gives higher instruction-level parallelism, so higher n easily wins
on traditional microbenchmarks on most CPUs. However, the larger
tables, which are accessed randomly, can be harmful in real-world
situations where the dcache may be cold or useful data may need be
evicted from the dcache. Meanwhile, today most architectures have
much faster CRC32 implementations using dedicated CRC32 instructions
or carryless multiplication instructions anyway, which make the
generic code obsolete in most cases especially on long messages.
Another reason for going with n=1 is that this is already what is
used by all the other CRC variants in the kernel. CRC32 was unique
in having support for larger tables. But as per the above this can
be considered an outdated optimization.
The standardization on slice-by-1 a.k.a. CRC32_SARWATE makes much of
the code in lib/crc32.c unused. A later patch will clean that up.

When retpolines and IBT are both disabled, the compiler is free to use
jump tables to optimize switch instructions. However, these are emitted
by Clang as absolute references into .rodata:
jmp *-0x7dfffe90(,%r9,8)
R_X86_64_32S .rodata+0x170
Given that this code will execute before that address in .rodata has even
been mapped, it is guaranteed to crash a SEV-SNP guest in a way that is
difficult to diagnose.
So disable jump tables when building this code. It would be better if we
could attach this annotation to the __head macro but this appears to be
impossible.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core and debugfs updates from Greg KH:
"Here is the big set of driver core and debugfs updates for 6.14-rc1.
Included in here is a bunch of driver core, PCI, OF, and platform rust
bindings (all acked by the different subsystem maintainers), hence the
merge conflict with the rust tree, and some driver core api updates to
mark things as const, which will also require some fixups due to new
stuff coming in through other trees in this merge window.
There are also a bunch of debugfs updates from Al, and there is at
least one user that does have a regression with these, but Al is
working on tracking down the fix for it. In my use (and everyone
else's linux-next use), it does not seem like a big issue at the
moment.
Here's a short list of the things in here:
- driver core rust bindings for PCI, platform, OF, and some i/o
functions.
We are almost at the "write a real driver in rust" stage now,
depending on what you want to do.
- misc device rust bindings and a sample driver to show how to use
them
- debugfs cleanups in the fs as well as the users of the fs api for
places where drivers got it wrong or were unnecessarily doing
things in complex ways.
- driver core const work, making more of the api take const * for
different parameters to make the rust bindings easier overall.
- other small fixes and updates

merge conflicts, and the one debugfs issue, which looks to be resolved

Add the const qualifier to all the ctl_tables in the tree except for
watchdog_hardlockup_sysctl, memory_allocation_profiling_sysctls,
loadpin_sysctl_table and the ones calling register_net_sysctl (./net,
drivers/inifiniband dirs). These are special cases as they use a
registration function with a non-const qualified ctl_table argument or
modify the arrays before passing them on to the registration function.
Constifying ctl_table structs will prevent the modification of
proc_handler function pointers as the arrays would reside in .rodata.
This is made possible after commit 78eb4ea25cd5 ("sysctl: treewide:
constify the ctl_table argument of proc_handlers") constified all the
proc_handlers.
Created this by running an spatch followed by a sed command:

"In this series, there are several major improvements such as folio
conversion by Matthew, speed-up of block truncation, and caching more
dentry pages.
In addition, we implemented a linear dentry search to address recent

get rid of.
Enhancements:
- foilio conversion in various IO paths
- optimize f2fs_truncate_data_blocks_range()
- cache more dentry pages

Pull nfsd updates from Chuck Lever:
"Jeff Layton contributed an implementation of NFSv4.2+ attribute
delegation, as described here:
https://www.ietf.org/archive/id/draft-ietf-nfsv4-delstid-08.html
This interoperates with similar functionality introduced into the
Linux NFS client in v6.11. An attribute delegation permits an NFS
client to manage a file's mtime, rather than flushing dirty data to
the NFS server so that the file's mtime reflects the last write, which
is considerably slower.
Neil Brown contributed dynamic NFSv4.1 session slot table resizing.
This facility enables NFSD to increase or decrease the number of slots
per NFS session depending on server memory availability. More session
slots means greater parallelism.
Chuck Lever fixed a long-standing latent bug where NFSv4 COMPOUND
encoding screws up when crossing a page boundary in the encoding
buffer. This is a zero-day bug, but hitting it is rare and depends on
the NFS client implementation. The Linux NFS client does not happen to
trigger this issue.
A variety of bug fixes and other incremental improvements fill out the
list of commits in this release. Great thanks to all contributors,
reviewers, testers, and bug reporters who participated during this
development cycle"

The enable_uring module parameter allows administrators to enable/disable
io-uring support for FUSE at runtime. However, disabling io-uring while
connections already have it enabled can lead to an inconsistent state.
Fix this by keeping io-uring enabled on connections that were already using
it, even if the module parameter is later disabled. This ensures active
FUSE mounts continue to function correctly.

When the fuse-server terminates while the fuse-client or kernel
still has queued URING_CMDs, these commands retain references
to the struct file used by the fuse connection. This prevents
fuse_dev_release() from being invoked, resulting in a hung mount
point.
This patch addresses the issue by making queued URING_CMDs
cancelable, allowing fuse_dev_release() to proceed as expected
and preventing the mount point from hanging.

On teardown struct file_operations::uring_cmd requests
need to be completed by calling io_uring_cmd_done().
Not completing all ring entries would result in busy io-uring
tasks giving warning messages in intervals and unreleased
struct file.
Additionally the fuse connection and with that the ring can
only get released when all io-uring commands are completed.
Completion is done with ring entries that are
a) in waiting state for new fuse requests - io_uring_cmd_done
is needed
b) already in userspace - io_uring_cmd_done through teardown
is not needed, the request can just get released. If fuse server
is still active and commits such a ring entry, fuse_uring_cmd()
already checks if the connection is active and then complete the
io-uring itself with -ENOTCONN. I.e. special handling is not
needed.
This scheme is basically represented by the ring entry state
FRRS_WAIT and FRRS_USERSPACE.
Entries in state:
- FRRS_INIT: No action needed, do not contribute to
ring->queue_refs yet
- All other states: Are currently processed by other tasks,
async teardown is needed and it has to wait for the two
states above. It could be also solved without an async
teardown task, but would require additional if conditions
in hot code paths. Also in my personal opinion the code
looks cleaner with async teardown.

In contrast to Grace Hopper systems, the HBM training has been moved
out of the UEFI on the Grace Blackwell systems. This reduces the system
bootup time significantly.
The onus of checking whether the HBM training has completed thus falls
on the module.
The HBM training status can be determined from a BAR0 register.
Similarly, another BAR0 register exposes the status of the CPU-GPU
chip-to-chip (C2C) cache coherent interconnect.
Based on testing, 30s is determined to be sufficient to ensure
initialization completion on all the Grace based systems. Thus poll
these register and check for 30s. If the HBM training is not complete
or if the C2C link is not ready, fail the probe.
While the time is not required on Grace Hopper systems, it is
beneficial to make the check to ensure the device is in an
expected state. Hence keeping it generalized to both the generations.
Ensure that the BAR0 is enabled before accessing the registers.

There is a HW defect on Grace Hopper (GH) to support the
Multi-Instance GPU (MIG) feature [1] that necessiated the presence
of a 1G region carved out from the device memory and mapped as
uncached. The 1G region is shown as a fake BAR (comprising region 2 and 3)
to workaround the issue.
The Grace Blackwell systems (GB) differ from GH systems in the following
aspects:
1. The aforementioned HW defect is fixed on GB systems.
2. There is a usable BAR1 (region 2 and 3) on GB systems for the
GPUdirect RDMA feature [2].
This patch accommodate those GB changes by showing the 64b physical
device BAR1 (region2 and 3) to the VM instead of the fake one. This
takes care of both the differences.
Moreover, the entire device memory is exposed on GB as cacheable to
the VM as there is no carveout required.
