Modern compilers are perfectly capable of extracting parallelism from
the XOR routines, provided that the prototypes reflect the nature of the
input accurately, in particular, the fact that the input vectors are
expected not to overlap. This is not documented explicitly, but is
implied by the interchangeability of the various C routines, some of
which use temporary variables while others don't: this means that these
routines only behave identically for non-overlapping inputs.
So let's decorate these input vectors with the __restrict modifier,
which informs the compiler that there is no overlap. While at it, make
the input-only vectors pointer-to-const as well.

In fact, in the kernel, AES-XTS is only used to operate on 4096 or 512

crypto: memneq - avoid implicit unaligned accesses
The C standard does not support dereferencing pointers that are not
aligned with respect to the pointed-to type, and doing so is technically
undefined behavior, even if the underlying hardware supports it.
This means that conditionally dereferencing such pointers based on
whether CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS=y is not the right thing
to do, and actually results in alignment faults on ARM, which are fixed
up on a slow path. Instead, we should use the unaligned accessors in
such cases: on architectures that don't care about alignment, they will
result in identical codegen whereas, e.g., codegen on ARM will avoid
doubleword loads and stores but use ordinary ones, which are able to
tolerate misalignment.

crypto: rsa-pkcs1pad - correctly get hash from source scatterlist
Commit
c7381b012872 ("crypto: akcipher - new verify API for public key
algorithms") changed akcipher_alg::verify to take in both the signature
and the actual hash and do the signature verification, rather than just
return the hash expected by the signature as was the case before. To do
this, it implemented a hack where the signature and hash are
concatenated with each other in one scatterlist.
Obviously, for this to work correctly, akcipher_alg::verify needs to
correctly extract the two items from the scatterlist it is given.
Unfortunately, it doesn't correctly extract the hash in the case where
the signature is longer than the RSA key size, as it assumes that the
signature's length is equal to the RSA key size. This causes a prefix
of the hash, or even the entire hash, to be taken from the *signature*.
(Note, the case of a signature longer than the RSA key size should not
be allowed in the first place; a separate patch will fix that.)
It is unclear whether the resulting scheme has any useful security
properties.
Fix this by correctly extracting the hash from the scatterlist.

Pull ftrace fix from Steven Rostedt:
"Fix s390 breakage from sorting mcount tables.
The latest merge of the tracing tree sorts the mcount table at build
time. But s390 appears to do things differently (like always) and
replaces the sorted table back to the original unsorted one. As the
ftrace algorithm depends on it being sorted, bad things happen when it
is not, and s390 experienced those bad things.
Add a new config to tell the boot if the mcount table is sorted or
not, and allow s390 to opt out of it"

ftrace: Fix assuming build time sort works for s390
Steven Rostedt (Google) [Sat, 22 Jan 2022 14:17:10 +0000 (09:17 -0500)]
ftrace: Fix assuming build time sort works for s390
To speed up the boot process, as mcount_loc needs to be sorted for ftrace
to work properly, sorting it at build time is more efficient than boot up
and can save milliseconds of time. Unfortunately, this change broke s390
as it will modify the mcount_loc location after the sorting takes place
and will put back the unsorted locations. Since the sorting is skipped at
boot up if it is believed that it was sorted at run time, ftrace can crash
as its algorithms are dependent on the list being sorted.
Add a new config BUILDTIME_MCOUNT_SORT that is set when
BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine
if sorting should take place at boot up.

Before said patch:
perf record -c 10000 -e arm_spe_0// -- sleep 1
Would yield an SPE event with period=10000. After the patch, the period
in "-c 10000" was being ignored because the arm-spe code initializes
sample_period to a non-zero value.

already resolved).
- Fix miscalculation of whether there's space available in
cachefiles.
- Make sure a default cache name is set on a cache if the user hasn't
set one by the time they bind the cache.
- Adjust the way the backing inode is presented in tracepoints, add a
tracepoint for mkdir and trace directory lookup.
- Add a tracepoint for failure to set the active file mark.
- Add an explanation of the checks made on the backing filesystem.
- Check that the backing filesystem supports tmpfile.
- Document how the page-release cancellation of the read-skip
optimisation works.
And I've included a change for netfslib:
- Make ops->init_rreq() optional"
