Remove crc32_le_combine() and crc32_le_shift(), since they are no longer
used.
Although combination is an interesting thing that can be done with CRCs,
it turned out that none of the users of it in the kernel were even close
to being worthwhile. All were much better off simply chaining the CRCs
or processing zeroes.
Let's remove the CRC32 combination code for now. It can come back
(potentially optimized with carryless multiplication instructions) if
there is ever a case where it would actually be worthwhile.

The MIPS32r2 ChaCha code has never been buildable with the clang
assembler. First, clang doesn't support the 'rotl' pseudo-instruction:
error: unknown instruction, did you mean: rol, rotr?
Second, clang requires that both operands of the 'wsbh' instruction be
explicitly given:
error: too few operands for instruction
To fix this, align the code with the real instruction set by (1) using
the real instruction 'rotr' instead of the nonstandard pseudo-
instruction 'rotl', and (2) explicitly giving both operands to 'wsbh'.
To make removing the use of 'rotl' a bit easier, also remove the
unnecessary special-casing for big endian CPUs at
.Lchacha_mips_xor_bytes. The tail handling is actually
endian-independent since it processes one byte at a time. On big endian
CPUs the old code byte-swapped SAVED_X, then iterated through it in
reverse order. But the byteswap and reverse iteration canceled out.
Tested with chacha20poly1305-selftest in QEMU using "-M malta" with both
little endian and big endian mips32r2 kernels.

Move the contents of arch/x86/lib/crypto/ into lib/crypto/x86/.
The new code organization makes a lot more sense for how this code
actually works and is developed. In particular, it makes it possible to
build each algorithm as a single module, with better inlining and dead
code elimination. For a more detailed explanation, see the patchset
which did this for the CRC library code:
https://lore.kernel.org/r/20250607200454.73587-1-ebiggers@kernel.org/.
Also see the patchset which did this for SHA-512:
https://lore.kernel.org/linux-crypto/20250616014019.415791-1-ebiggers@kernel.org/
This is just a preparatory commit, which does the move to get the files
into their new location but keeps them building the same way as before.
Later commits will make the actual improvements to the way the
arch-optimized code is integrated for each algorithm.
Add a gitignore entry for the removed directory arch/x86/lib/crypto/ so
that people don't accidentally commit leftover generated files.

Instead of exposing the x86-optimized SHA-512 code via x86-specific
crypto_shash algorithms, instead just implement the sha512_blocks()
library function. This is much simpler, it makes the SHA-512 (and
SHA-384) library functions be x86-optimized, and it fixes the
longstanding issue where the x86-optimized SHA-512 code was disabled by
default. SHA-512 still remains available through crypto_shash, but
individual architectures no longer need to handle it.
To match sha512_blocks(), change the type of the nblocks parameter of
the assembly functions from int to size_t. The assembly functions
actually already treated it as size_t.

Since HMAC support is commonly needed and is fairly simple, include it
as a first-class citizen of the SHA-512 library.
The API supports both incremental and one-shot computation, and either
preparing the key ahead of time or just using a raw key. The
implementation is much more streamlined than crypto/hmac.c.

Add basic support for SHA-384 and SHA-512 to lib/crypto/.
Various in-kernel users will be able to use this instead of the
old-school crypto API, which is harder to use and has more overhead.
The basic support added by this commit consists of the API and its
documentation, backed by a C implementation of the algorithms.
sha512_block_generic() is derived from crypto/sha512_generic.c.

While at it, also sort the include lists alphabetically. (Keep
asm/irqflags.h last, as otherwise it doesn't build on alpha.)
This handles all of lib/crypto/, but not arch/*/lib/crypto/. The
exports in arch/*/lib/crypto/ will go away when the code is properly

Pull RISC-V Fixes for 5.16-rc4
- .rodata is no longer linkd into PT_DYNAMIC.
It was not supposed to be there in the first place and resulted in
invalid (but unused) entries. This manifests as at least warnings in
llvm-readelf
- A fix for runtime constants with all-0 upper 32-bits. This should
only manifest on MMU=n kernels
- A fix for context save/restore on systems using the T-Head vector
extensions
- A fix for a conflicting "+r"/"r" register constraint in the VDSO
getrandom syscall wrapper, which is undefined behavior in clang
- A fix for a missing register clobber in the RVV raid6 implementation.
This manifests as a NULL pointer reference on some compilers, but
could trigger in other ways
- Misaligned accesses from userspace at faulting addresses are now
handled correctly
- A fix for an incorrect optimization that allowed access_ok() to mark
invalid addresses as accessible, which can result in userspace
triggering BUG()s

percpu variable tag->counters
When loading a module, as long as the module has memory allocation
operations, kmemleak produces a false positive report that resembles the
following:
unreferenced object (percpu) 0x7dfd232a1650 (size 16):
comm "modprobe", pid 1301, jiffies 4294940249
hex dump (first 16 bytes on cpu 2):

This is because the module can only indirectly reference
alloc_tag_counters through the alloc_tag section, which misleads kmemleak.
However, we don't have a kmemleak ignore interface for percpu allocations
yet. So let's create one and invoke it for tag->counters.

Currently, the in-kernel kunit test case timeout is 300 seconds. (There
is a separate timeout mechanism for the whole test execution in
kunit.py, but that's unrelated.) However, tests marked 'slow' or 'very
slow' may timeout, particularly on slower machines.
Implement a multiplier to the test-case timeout, so that slower tests
have longer to complete:
- DEFAULT -> 1x default timeout
- KUNIT_SPEED_SLOW -> 3x default timeout
- KUNIT_SPEED_VERY_SLOW -> 12x default timeout
A further change is planned to allow user configuration of the
default/base timeout to allow people with faster or slower machines to
adjust these to their use-cases.

Add test cases for static and dynamic minor number allocation and
deallocation.
While at it, improve description and test suite name.
Some of the cases include:
- that static and dynamic allocation reserved the expected minors.
- that registering duplicate minors or duplicate names will fail.
- that failing to create a sysfs file (due to duplicate names) will
deallocate the dynamic minor correctly.
- that dynamic allocation does not allocate a minor number in the static
range.
- that there are no collisions when mixing dynamic and static allocations.
- that opening devices with various minor device numbers work.
- that registering a static number in the dynamic range won't conflict with
a dynamic allocation.
This last test verifies the bug fixed by commit 6d04d2b554b1 ("misc:
misc_minor_alloc to use ida for all dynamic/misc dynamic minors") has not
regressed.

Add a simple stress test for lib/ratelimit.c
To run on x86:
./tools/testing/kunit/kunit.py run --arch x86_64 --kconfig_add CONFIG_RATELIMIT_KUNIT_TEST=y --kconfig_add CONFIG_SMP=y --qemu_args "-smp 4" lib_ratelimit
On a 16-CPU system, the "4" in "-smp 4" can be varied between 1 and 8.
Larger numbers have higher probabilities of introducing delays that
break the smoke test. In the extreme case, increasing the number to
larger than the number of CPUs in the underlying system is an excellent
way to get a test failure.

With sanitizers enabled, this function uses a lot of stack, causing
a harmless warning:
lib/test_objagg.c: In function 'test_hints_case.constprop':
lib/test_objagg.c:994:1: error: the frame size of 1440 bytes is larger than 1408 bytes [-Werror=frame-larger-than=]
Most of this is from the two 'struct world' structures. Since most of
the work in this function is duplicated for the two, split it up into
separate functions that each use one of them.
The combined stack usage is still the same here, but there is no warning
any more, and the code is still safe because of the known call chain.

Temporarily clear the preallocation flag when explicitly requesting
allocations. Pre-existing allocations are already counted against the
request through mas_node_count_gfp(), but the allocations will not happen
if the MA_STATE_PREALLOC flag is set. This flag is meant to avoid
re-allocating in bulk allocation mode, and to detect issues with
preallocation calculations.
The MA_STATE_PREALLOC flag should also always be set on zero allocations
so that detection of underflow allocations will print a WARN_ON() during
consumption.
User visible effect of this flaw is a WARN_ON() followed by a null pointer
dereference when subsequent requests for larger number of nodes is
ignored, such as the vma merge retry in mmap_region() caused by drivers
altering the vma flags (which happens in v6.6, at least)

ref_tracker: add ability to register a debugfs file for a ref_tracker_dir
For those just joining in, this series adds a new top-level
"ref_tracker" debugfs directory, and has each ref_tracker_dir register a
file in there as part of its initialization. It also adds the ability to
register a symlink with a more human-usable name that points to the
file, and does some general cleanup of how the ref_tracker object names
are handled.

Currently, there is no convenient way to see the info that the
ref_tracking infrastructure collects. Attempt to create a file in
debugfs when called from ref_tracker_dir_init().
The file is given the name "class@%px", as having the unmodified address
is helpful for debugging. This should be safe since this directory is only
accessible by root
While ref_tracker_dir_init() is generally called from a context where
sleeping is OK, ref_tracker_dir_exit() can be called from anywhere.
Thus, dentry cleanup must be handled asynchronously.
Add a new global xarray that has entries with the ref_tracker_dir
pointer as the index and the corresponding debugfs dentry pointer as the
value. Instead of removing the debugfs dentry, have
ref_tracker_dir_exit() set a mark on the xarray entry and schedule a
workqueue job. The workqueue job then walks the xarray looking for
marked entries, and removes their xarray entries and the debugfs
dentries.
Because of this, the debugfs dentry can outlive the corresponding
ref_tracker_dir. Have ref_tracker_debugfs_show() take extra care to
ensure that it's safe to dereference the dir pointer before using it.

A later patch in the series will be adding debugfs files for each
ref_tracker that get created in ref_tracker_dir_init(). The format will
be "class@%px". The current "name" string can vary between
ref_tracker_dir objects of the same type, so it's not suitable for this
purpose.
Add a new "class" string to the ref_tracker dir that describes the
the type of object (sans any individual info for that object).
Also, in the i915 driver, gate the creation of debugfs files on whether
the dentry pointer is still set to NULL. CI has shown that the
ref_tracker_dir can be initialized more than once.

In a later patch, we'll be adding a 3rd mechanism for outputting
ref_tracker info via seq_file. Instead of a conditional, have the caller
set a pointer to an output function in struct ostream. As part of this,
the log prefix must be explicitly passed in, as it's too late for the
pr_fmt macro.

As Thomas Weißschuh points out [1], it is now preferable to use %p
instead of hashed pointers with printk(), since raw pointers should no
longer be leaked into the kernel log. Change the ref_tracker
infrastructure to use %p instead of %pK in its formats.

allocation may exhaust module loader limit on smaller systems
Previous releases - regressions:
- tcp: fix tcp_packet_delayed() for peers with no selective ACK
support
Previous releases - always broken:
- wifi: ath12k: don't activate more links than firmware supports

__kunit_activate_static_stub() works effectively as
kunit_deactivate_static_stub() if `replacement_addr` is NULL.
Add a test case to catch the issue discovered in
commit 772e50a76ee6 ("kunit: Fix wrong parameter to kunit_deactivate_static_stub()").
For running the test:
$ ./tools/testing/kunit/kunit.py run \
--arch=x86_64 \
kunit_stub
