Pull crypto fixes from Herbert Xu:
- A long-standing bug in crypto_engine
- A buggy but harmless check in the sun8i-ss driver
- A regression in the CRYPTO_USER interface
* tag 'v6.4-p2' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: api - Fix CRYPTO_USER checks for report function
crypto: engine - fix crypto_queue backlog handling
crypto: sun8i-ss - Fix a test in sun8i_ss_setup_ivs()

SS_ENCRYPTION is (0 << 7 = 0), so the test can never be true.
Use a direct comparison to SS_ENCRYPTION instead.
The same king of test is already done the same way in sun8i_ss_run_task().

git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
Pull MM updates from Andrew Morton:
- Nick Piggin's "shoot lazy tlbs" series, to improve the peformance of
switching from a user process to a kernel thread.
- More folio conversions from Kefeng Wang, Zhang Peng and Pankaj
Raghav.
- zsmalloc performance improvements from Sergey Senozhatsky.
- Yue Zhao has found and fixed some data race issues around the
alteration of memcg userspace tunables.
- VFS rationalizations from Christoph Hellwig:
- removal of most of the callers of write_one_page()
- make __filemap_get_folio()'s return value more useful
- Luis Chamberlain has changed tmpfs so it no longer requires swap
backing. Use `mount -o noswap'.
- Qi Zheng has made the slab shrinkers operate locklessly, providing
some scalability benefits.
- Keith Busch has improved dmapool's performance, making part of its
operations O(1) rather than O(n).
- Peter Xu adds the UFFD_FEATURE_WP_UNPOPULATED feature to userfaultd,
permitting userspace to wr-protect anon memory unpopulated ptes.
- Kirill Shutemov has changed MAX_ORDER's meaning to be inclusive
rather than exclusive, and has fixed a bunch of errors which were
caused by its unintuitive meaning.
- Axel Rasmussen give userfaultfd the UFFDIO_CONTINUE_MODE_WP feature,
which causes minor faults to install a write-protected pte.
- Vlastimil Babka has done some maintenance work on vma_merge():
cleanups to the kernel code and improvements to our userspace test
harness.
- Cleanups to do_fault_around() by Lorenzo Stoakes.
- Mike Rapoport has moved a lot of initialization code out of various
mm/ files and into mm/mm_init.c.
- Lorenzo Stoakes removd vmf_insert_mixed_prot(), which was added for
DRM, but DRM doesn't use it any more.
- Lorenzo has also coverted read_kcore() and vread() to use iterators
and has thereby removed the use of bounce buffers in some cases.
- Lorenzo has also contributed further cleanups of vma_merge().
- Chaitanya Prakash provides some fixes to the mmap selftesting code.
- Matthew Wilcox changes xfs and afs so they no longer take sleeping
locks in ->map_page(), a step towards RCUification of pagefaults.
- Suren Baghdasaryan has improved mmap_lock scalability by switching to
per-VMA locking.
- Frederic Weisbecker has reworked the percpu cache draining so that it
no longer causes latency glitches on cpu isolated workloads.

flushing.
- David Stevens has fixed several issues involving khugepaged,
userfaultfd and shmem.
- Christoph Hellwig has provided some cleanup work to zram's IO-related
code paths.

MAX_ORDER currently defined as number of orders page allocator supports:
user can ask buddy allocator for page order between 0 and MAX_ORDER-1.
This definition is counter-intuitive and lead to number of bugs all over
the kernel.
Change the definition of MAX_ORDER to be inclusive: the range of orders
user can ask from buddy allocator is 0..MAX_ORDER now.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH:
"Here is the large set of driver core changes for 6.4-rc1.
Once again, a busy development cycle, with lots of changes happening
in the driver core in the quest to be able to move "struct bus" and
"struct class" into read-only memory, a task now complete with these
changes.
This will make the future rust interactions with the driver core more
"provably correct" as well as providing more obvious lifetime rules
for all busses and classes in the kernel.
The changes required for this did touch many individual classes and
busses as many callbacks were changed to take const * parameters
instead. All of these changes have been submitted to the various
subsystem maintainers, giving them plenty of time to review, and most
of them actually did so.
Other than those changes, included in here are a small set of other
things:
- kobject logging improvements
- cacheinfo improvements and updates
- obligatory fw_devlink updates and fixes
- documentation updates
- device property cleanups and const * changes
- firwmare loader dependency fixes.
All of these have been in linux-next for a while with no reported
problems"

driver core: Don't require dynamic_debug for initcall_debug probe timing
firmware_loader: rework crypto dependencies

zram: fix up permission for the hot_add sysfs file
cacheinfo: Add use_arch[|_cache]_info field/function
arch_topology: Remove early cacheinfo error message if -ENOENT
cacheinfo: Check cache properties are present in DT
cacheinfo: Check sib_leaf in cache_leaves_are_shared()
cacheinfo: Allow early level detection when DT/ACPI info is missing/broken
cacheinfo: Add arm64 early level initializer implementation

In the function, qm_get_qos_value(), a struct bus_type * is used, but it
really should be a const pointer as it is not modified anywhere in the
function, and the driver core function it is used in expects a constant
pointer.

The module pointer in class_create() never actually did anything, and it
shouldn't have been requred to be set as a parameter even if it did
something. So just remove it and fix up all callers of the function in
the kernel tree at the same time.

The crypt_ctl structure must be exactly 64 bytes long to work correctly,
and it has to be a power-of-two size to allow turning the
64-bit division in crypt_phys2virt() into a shift operation, avoiding
the link failure:
ERROR: modpost: "__aeabi_uldivmod" [drivers/crypto/intel/ixp4xx/ixp4xx_crypto.ko] undefined!
The failure now shows up because the driver is available for compile
testing after the move, and a previous fix turned the more descriptive
BUILD_BUG_ON() into a link error.
Change the variably-sized dma_addr_t into the expected 'u32' type that is
needed for the hardware, and reinstate the size check for all 32-bit
architectures to simplify debugging if it hits again.

caam driver needs to be aware of OP-TEE f/w presence, since some things
are done differently:
1. there is no access to controller's register page (note however that
some registers are aliased in job rings' register pages)
2 Due to this, MCFGR[PS] cannot be read and driver assumes
MCFGR[PS] = b'0 - engine using 32-bit address pointers.
This is in sync with the fact that:
-all i.MX SoCs currently use MCFGR[PS] = b'0
-only i.MX OP-TEE use cases don't allow access to controller register page

Avoiding detecting finely in-place operations with different
scatter lists. Copying the source data for decryption into rctx->lastc
regardless if the operation is in-place or not. This allows in-place
operations with different scatter lists.
This approach takes less resources than parsing both scatter lists to
check if they are equal.

regardless if the operation is in-place or not. This allows in-place
operations with different scatter lists without affecting other
operations.
This approach takes less resources than parsing both scatter lists to
check if they are equal.

Create a separate drivers/crypto/intel/ixp4xx directory and move
drivers/crypto/ixp4xx_crypto.c to it, along with a new Kconfig and
Makefile to contain the config and make bits.
Also add a COMPILE_TEST dependency to CRYPTO_DEV_IXP4XX so it can be
more easily compile-tested.

The PSP IRQ is edge-triggered (MSI or MSI-X) in all cases supported by
the psp module so clear the interrupt status register early in the
handler to prevent missed interrupts. sev_irq_handler() calls wake_up()
on a wait queue, which can result in a new command being submitted from
a different CPU. This then races with the clearing of isr and can result
in missed interrupts. A missed interrupt results in a command waiting
until it times out, which results in the psp being declared dead.
This is unlikely on bare metal, but has been observed when running
virtualized. In the cases where this is observed, sev->cmdresp_reg has
PSP_CMDRESP_RESP set which indicates that the command was processed
correctly but no interrupt was asserted.
The full sequence of events looks like this:
CPU 1: submits SEV cmd #1
CPU 1: calls wait_event_timeout()
CPU 0: enters psp_irq_handler()
CPU 0: calls sev_handler()->wake_up()
CPU 1: wakes up; finishes processing cmd #1
CPU 1: submits SEV cmd #2
CPU 1: calls wait_event_timeout()
PSP: finishes processing cmd #2; interrupt status is still set; no interrupt
CPU 0: clears intsts
CPU 0: exits psp_irq_handler()
CPU 1: wait_event_timeout() times out; psp_dead=true

A platform device's remove callback is only ever called after the probe
callback returned success.
In the case of kmb_ocs_aes_remove() this means that kmb_ocs_aes_probe()
succeeded before and so platform_set_drvdata() was called with a
non-zero argument and platform_get_drvdata() returns non-NULL.
This prepares making remove callbacks return void.

The Crypto API hashing paradigm requires the hardware state to
be exported between *each* request because multiple unrelated
hashes may be processed concurrently.
The stm32 hardware is capable of producing the hardware hashing
state but it was only doing it in the export function. This is
not only broken for export as you can't export a kernel pointer
and reimport it, but it also means that concurrent hashing was
fundamentally broken.
Fix this by moving the saving and restoring of hardware hash
state between each and every hashing request.

The current finup code is unnecessarily convoluted. There is no
need to call update and final separately as update already does
all the necessary work on its own.
Simplify this by utilising the HASH_FLAGS_FINUP bit in rctx to
indicate only finup and use the HASH_FLAGS_FINAL bit instead to
signify processing common to both final and finup.
