Pull TPM updates from Jarkko Sakkinen:
"Features and Improvements:
- improve tpm_crb behaviour by putting the chip into an idle state
for each transmission. This improves firmware behavior as the
kernel now better cancels its state as if it had never touched it
in the first place.
- Drop a spurious (but harmless) wmb() from tpm_pm_resume().
- tpm_tis_i2c now requests the optional reset control and deasserts
it before communicating with the TPM.
- replace SIMPLE_DEV_PM_OPS with DEFINE_SIMPLE_DEV_PM_OPS across the
whole driver stack.
- Validate during driver initialization that no duplicate banks are
received. It's unlikely corruption but since it happening would
cause oops I decided to retain it as a sanity check.
Bug fixes:
- tpm2_probe() misinterpreted a transport error on TPM2_GetCapability
as the chip not being probed, and the chip was detected as a TPM 1
chip.
This can happen in reality only in the extremely rare case of bus
corruption. Despite the odds, a fix was landed, as it is still
technically a legit bug fix.
- It is not really worth the time and energy to go into details as
tpm_nsc is a somewhat legacy driver, but one null pointer
dereference bug and another causing use-after-free were fixed.
- read() of /dev/tpm{,rm}0 with zero size caused a pending response
to be consumed. Just return immediately"

Pull CXL updates from Dave Jiang:
"The headline item is the first part of support for Dynamic Capacity
Devices (DCD). It covers flagging DCD support in the mailbox, reading
the dynamic capacity configuration from the device, gathering DSMAS
data for the DCD partitions, and configuring the dynamic capacity
interrupts. It also adds a documentation update and a cleanup that
enforces partition ordering. DCD is not enabled yet with these code
changes. Patches are applied to reduce the whole set in order to
relief the burden of very large patch set review.
Zero sized HDM decoders are now allowed, along with cxl_test support
for them. There is also a set of decoder hardening patches for switch
decoder enumeration. Latency calculations now account for link width
and use consistent units. The GPF timeout programming has been
reworked. The pull also has a number of misc patches.
A large number of bug fixes against pre-existing issues make up the
rest of the pull. Many of these were flagged by review of patches
posted to the mailing list by sashiko.
Also adding Richard Cheng as a reviewer (R) to the CXL sub-system"

Pull sh updates from John Paul Adrian Glaubitz:
"Fixes and improvements for various boards as well as the generic sh
kernel:
- help the mach-x3proto and ecovec24 boards get rid off the use of
the old platform data API in the kernel. For the former board,
software nodes are being used for gpio-keys now while for the
latter board, static device properties are used to describe the
touchscreen (Dmitry Torokhov)
- a build fix when CONFIG_BUILTIN_DTB is enabled, and fix an issue
with __get_user_u64() and __put_user_u64() using wrong memory
operands which could cause the kernel build to fail with "invalid
'asm'" or an internal compiler error in GCC's change_address_1
(Florian Fuchs)
- update various default configuration files of several boards to
replace the removed CONFIG_USB_GADGET_M66592 with the new
CONFIG_USB_M66592 Kconfig option (Pengpeng Hou)
- fix two issues with the SH-7785LCR evaluation board: fix a kernel
memory leak which occurred as a result of the prio and sense lists
being sorted too early in register_intc_controller(), and fix the
the registration of the PCA9564 controller so that the RTC works
properly again (Karl Mehltretter)
- fix missing cookies when calling free_irq() in the maple bus driver
which ensures that IRQ handlers can be properly unregistered and
the kernel does not emit a WARN message (Runyu Xiao)
- select BINFMT_FLAT_NO_DATA_START_OFFSET for !MMU configurations
such that there is no gap at the end of text and init runs which
causes the GOT register to point below the real GOT, so every GOT
load reads the neighbouring slot and gets a wrong pointer (Waldemar
Brodkorb)"

list_first_entry() does not return NULL on an empty list; it returns a
bogus pointer computed by container_of() from the list head.
atmel_lcdfb_probe() initializes info->modelist with INIT_LIST_HEAD()
and later takes its first entry with list_first_entry(), assuming
atmel_lcdfb_of_init() populated it. However, atmel_lcdfb_of_init()
drops the return value of fb_add_videomode() — unlike every other
fallible call in the same function — so if fb_add_videomode() fails
(its internal kmalloc can return -ENOMEM under memory pressure or
fault injection), the list stays empty while of_init() reports
success. The probe path then dereferences the bogus pointer in
fb_videomode_to_var(&info->var, &modelist->mode). Because the bogus
pointer lands inside the contiguous fb_info allocation, this may not
fault immediately; instead it silently reads adjacent memory as a
struct fb_videomode and programs garbage timing parameters into the
LCD controller. This was found by code audit; we do not have Atmel
hardware to reproduce it.
Fix this on two levels: check the return value of fb_add_videomode()
in atmel_lcdfb_of_init() so the failure is propagated (root cause),
and use list_first_entry_or_null() in atmel_lcdfb_probe() with a NULL
check that fails probe gracefully with -EINVAL (defense in depth),
consistent with the surrounding error handling which bails out to
stop_clk.

Add struct consw.con_unblank as inverse operation to con_blank.
If implemented invoke con_blank to turn the console from blanked to
unblanked. Also update the semantics of con_blank in this case: The
blank parameter of con_blank receives a VESA blank mode from enum
vesa_blank_mode instead of the hybrid unblank/blank values it has
used so far.
With con_unblank not implemented, invoke con_blank for blanking and
unblanking as before.
The old semantics of con_blank will be removed when all consoles
implement con_unblank.

Pull EFI updates from Ard Biesheuvel:
- Set the LoaderDevicePartUUID EFI variable from the stub to help
systemd discover the file system layout when booting straight into
Linux without GRUB or systemd-boot (Vincent Mailhol)
- Some GUID deduplication work from Vincent
- Remove pointless UTF16->UTF8 and vice versa conversions from the stub
- Some kmap() -> kmap_local_page() conversions in the capsule loader
- Add a runtime control to en/disable EFI runtime services so that
PREEMPT_RT systems can enable them as needed
- Add a 'nostatfs' mount option to efivarfs so that the cost of
querying the EFI variable store (which is already rate limited) can
be avoided entirely on systems where it is disproportionately costly
- Rework the EFI libstub Makefile to align x86 with other
architectures, and inherit/adapt the global CFLAGS variable rather
than reconstruct it from scratch
- Constify attributes of statically allocated sysfs nodes
- Avoid register x18 when building the arm64 EFI stub, in order to
comply with the UEFI spec, and to permit it to execute in a context
where x18 is special

- cfi_cmdset_0002: cap the write-buffer chunk at 256 bytes on an x8 device
Raw NAND:
- Clean up the Qualcomm controller driver again
- Improve / create Arasan and IBM
- Reflect that ESMT and GigaDevice share ID 0xc8, and disable broken
timings feature on GD9FU2G8F3A
- Drop platform data support from the lpc32xx drivers
SPI NAND:

- Winbond: Add support for W25N04LW and W25N08LW
- Support for ISSI SPI NAND flashes
SPI NOR:
- Support for new Macronix and (lots of) Winbond flash devices
- Rewrite the status register handling. There were many small helper
functions to enable quad I/O mode in many different ways. That's
now consolidated in one generic function.
- Rework the SFPD handling. It used to be only parsed for flashes
present in the in-kernel database which had any of the multi-I/O
bit set - or with the addition of generic flash driver for any
unknown flashes. This left a gap where SFDP wasn't handled and it
turns out newer flashes (with SFDP support) will reused IDs of just
these old flashed. With the rework, SFDP is tried to be parsed for
any flashes and will amend the information which is already present
in the in-kernel database.
- Increase SFDP size limit to 16KiB. There are flashes which have
some larger gaps between tables and thus exceeds the former 4KiB
limit.
- Flash fixups are getting more and more common. Due to this, the
fixups are now a separate list (per manufacturer) instead of being
attached to a specific flash. A new .match() callback makes them
more flexible, when one is applied.
- Support 1-1-8 and 1-8-8 modes with larger flashes which need 4byte
addresses
Then there is the load of API updates and misc AI fixes"

Pull firewire updates from Takashi Sakamoto:
- Guarantee asynchronous packet and transaction callbacks in process
context
Both the 1394 OHCI driver and the core transaction layer have been
changed to guarantee that asynchronous packet and transaction
callbacks are invoked in process context. In v6.17, the execution
context depended on the transaction destination: callbacks for
transactions destined for remote nodes were invoked from a workqueue,
whereas callbacks for transactions destined for the local node or
terminated due to internal errors were invoked in the transaction
initiator's context.
All such callbacks are now guaranteed to execute in process context,
eliminating the need to account for different execution contexts when
implementing callback functions.
- Fill kerneldoc for transaction layer
The above change guarantees a consistent execution context for packet
and transaction callbacks, making it possible to document their
execution context in kerneldoc.
- Enable compiler-based context analysis for the transaction layer
The core transaction layer is sufficiently complex that
compiler-based context analysis can help detect invalid call paths.
- Fix a reference count leak in the cdev layer
A reference count leak was reported when a user space application
delegated isochronous resource management. This issue has now been
fixed.
- Add KUnit tests for the configuration ROM parser and generator
In recent years, questions have been raised about how the
configuration ROM parser and generator handle boundary conditions and
edge cases. KUnit tests have been added to verify their behavior in
these situations. KUNIT_STATIC_STUB_REDIRECT is used to stub the
transaction responder so that it returns the configuration ROM
contents.
- Misc fixes for kerneldoc and nosy-dump application

Pull staging driver updates from Greg KH:
"Here is the big set of staging driver updates for 7.4-rc1.
The huge majority of changes in here were to the rtl8723bs driver,
which ended up being deleted entirely through the wifi driver tree, so
while the work here was nice to have done to get experience by people,
the overall goal was achieved in that we have a solid working and sane
driver in the real part of the tree now.
Other than that, included in here are:
- some greybus driver removal of broken drivers that no one ever used
- minor coding style cleanups for other staging drivers
All of these have been in linux-next with no reported issues, other
than the merge conflict of the driver being removed, but that's an
obvious one to resolve :)"

Pull SCSI updates from James Bottomley:
"Small number of driver updates (mpi3mr, ufs, scsi_debug).
By far the biggest core change (at 4000+ lines) is the sense code
rework to make our sense handling follow the 16 bit defines in the
SCSI standard rather than our split ASC and ASCQ handling which ends
up being confusing and difficult to grep.

Pull io_uring updates from Jens Axboe:
"The bulk of this is a big robustness pass over cancelation, io-wq,
timeouts, and poll. Outside of that:
- Large series from Josef hardening the cancelation, io-wq, timeout,
poll, and wait paths. Fixes for lost wakeups and lost cancels as
io-wq arms poll/timeouts, work stranding on worker exit, CQE32
resize handling, napi entry timeouts, and a pile of smaller
correctness issues across the board
- Rework of how io-wq posts completions, posting from the last
request reference and dropping the request file before the
completion, and running ring release cancelations synchronously -
canceling and waiting for all in-flight requests and dropping
registered files and buffers at release time
- Don't charge the SQ/CQ rings or provided buffer rings to
RLIMIT_MEMLOCK, which the region API conversion had started doing
- Split io_uring_cmd_set_res() out from io_uring_cmd_done() so a
command can set the result from its ->end_io() handler, used by
nvme
- CQE32 ring fixes for the free entry check, aux CQE big_cqe zeroing,
and the dummy skip CQE
- Timeout fixes for sequence handling and multishot updates
- net fixes for MSG_TRUNC buffer overconsumption and keeping recv
buffer select length within MAX_RW_COUNT

Adjust code which inadvertently perform redundant checks on hugetlb VMAs
and clean them up:
* hugetlb VMAs have VMA_DONTEXPAND_BIT set so a VMA_SPECIAL_FLAGS check
suffices. (migrate_vma_setup() regains an explicit hugetlb test later in
the series, once VMA_SPECIAL_FLAGS is removed.)
* hugetlb VMAs unconditionally set vma->vm_ops, so they are never
anonymous.
* hugetlb VMAs do not set VMA_PFNMAP_BIT so checking for this is redundant.
While we're here also drop a VM_BUG_ON() which the simplified check above
makes unreachable, and use the new VMA flag API.
No functional change intended.

The is_vm_hugetlb_page() predicate is badly named - the mapping can span
more than a page and it is inconsistent with other VMA predicates that
typically are prefixed by vma_.
Rename to vma_is_hugetlb() for consistency, and while we're here update
some VM_BUG_ON_VMA() to VM_WARN_ON_ONCE_VMA() as to avoid unnecessary
oopses.
No functional change intended.

This header really makes little sense - every place it is included mm.h is
also included, and the header itself includes mm.h, so it does nothing to
reduce header size.
It also oddly does an #ifdef around checking VMA_HUGETLB_BIT, however
VMA_HUGETLB_BIT is unconditionally available, and will never be set if
hugetlb is not enabled.
Simply remove the header, eliminate the odd ifdeffery and place the
predicates in mm.h.
The naming of these predicates is odd, but to keep changes separate, we
will address this in a separate patch.
The file was never put into MAINTAINERS so there's no change required
there.
No functional change intended.

Use the mmap_prepare in favour of the deprecated mmap hook as part of the
work to convert one to another.
Since this is simply a refcounted kernel page that has been allocated, it
should not be marked VM_IO and should be inserted using the kernel page
insertion mechanism, so convert it to do this instead.
Use the VMA descriptor's private data field as a scratch buffer to store
the page in - this stays valid throughout the kernel page mapping
operation.

Currently all drivers which use defio allocate system memory. All of them
also set FBINFO_VIRTFB, other than ssd1307fb, however this driver allocates
system RAM, so simply failed to set this flag when it ought to.
This patch sets FBINFO_VIRTFB on ssd1307fb probe, then drops setting VM_IO
in fb_deferred_io_mmap() and instead requires FBINFO_VIRTFB to be set,
erroring out with a kernel warning if not.
The logic requires a page from the driver and since commit 1ecbc7dd2902
("fbdev/deferred-io: Always call get_page() for framebuffer pages") has
always required it to be refcounted, so this was implicitly already the
case.
Finally this patch sets VM_MIXEDMAP, as the logic is mapping
kernel-allocated memory so this is appropriate.

Move from the deprecated mmap hook to the new mmap_prepare hook.
We are mapping kernel pages here, so use the discontiguous kernel mapping
mmap action to do so.
Unwind the rather confusing loop and instead map as many pages as we can at
one time.
Note that we do not need to pay attention to rsv_schp->k_use_sg here, as
the pages are populated for the length of the buffer at
rsv_schp->page_order granularity as compound pages.
The discontiguous kernel page mapping logic handles the compound pages for
us.
sfp->mmap_called keeps the buffer stable for us. As before it is never
cleared, so a failed mmap also leaves it set.
We also remove some useless vma, vma->vm_file NULL checks - these will
always be non-NULL if you reached the mmap hook logic.
We retain log output for consistency, but change what's output on page
mapping to indicate that sg_discontig_get() does the work now.
Note that we drop the VMA_IO_BIT flag for the VMA here. It was never
necessary as we invoke alloc_pages() which gives us refcounted folios that
are fine for GUP to access (VMA_IO_BIT would prevent that).

In cases which map chip memory from vmalloc()'d ranges, the hfi1 infiniband
drivers currently installs a fault handler, and then smuggles the kernel
virtual address of this range in vma->vm_pgoff.
This is exposing KASLR-sensitive internal kernel state in the VMA, and is
entirely unnecessary.
Instead, use remap_vmalloc_range() to remap the VMA to the span, and
eliminate the fault handler altogether.
remap_vmalloc_range() checks that the VMA does not extend beyond the
vmalloc area, and the driver already requires the VMA to exactly match the
span of the memory being mapped, so this has no impact.
The memory is all preallocated so not having a fault handler has no impact
either, other than pre-mapping the ranges which is beneficial.
We also remove the VM_IO flag as it's not appropriate here, and the
VM_DONTEXPAND flag as remap_vmalloc_range() will set it (and also mark the
range correctly as a mixed map).
We also update the vmalloc paths to place the virtual kernel address in
memvirt, rather than overloading the physical address memaddr. We predicate
the vmalloc handling on the vmalloc flag before we check memvirt for the
virtual address-derived PFN remap path, so this works fine.
remap_vmalloc_range() requires that the vmalloc()'d areas were all
allocated using vmalloc_user() - each of cq->comps,
uctxt->subctxt_rcvegrbuf, uctxt->subctxt_rcvhdr_base,
uctxt->subctxt_uregbase and dd->events were allocated this way, so that
requirement is satisfied.
We also remove VM_IO and VM_DONTEXPAND from the STATUS command, as these
are both set on remap.
Finally, we remove VM_DONTEXPAND from the PIO_BUFS, PIO_BUFS_SOP and UREGS
commands, as these are also all set on remap. PIO_CRED retains it, as
dma_mmap_coherent() may map via vm_insert_page() on the IOMMU-DMA path,
which sets only VM_MIXEDMAP. The RCV_HDRQ, RCV_EGRBUF and RTAIL commands
also map via dma_mmap_coherent() and never set VM_DONTEXPAND, so set it for
them for the same reason.
Note that we retain expected behaviour throughout - the vmalloc remapped
ranges set VM_MIXEDMAP | VM_DONTDUMP | VM_DONTEXPAND for each range.
VM_IO was never appropriate as the ranges are explicitly not MMIO, and the
reference to the v3.7 VM_RESERVED semantics map on to VM_MIXEDMAP |
VM_DONTDUMP | VM_DONTEXPAND correctly - no core dump, unmergeable, no
normal vm page for purposes of reclaim/migration/etc.
There is a change in behaviour in that pages mapped using
remap_vmalloc_range() will now have normal GUP-able pages, however this
should have no impact as there is no reason not to allow this.

Replace the deprecated .mmap hook with its replacement .mmap_prepare. As
part of this change, additionally take the approach of mapping pages upon
mmap rather than providing a fault handler.
The page span cannot be mutated when an mmap mapping is in place, so this
is safe to do in advance (the MON_IOCT_RING_SIZE ioctl operation exits
-EBUSY if it's attempted, gated by the rp->mmap_active reference count).
Utilise the newly introduced mmap_action_map_discontig_kernel_pages() to do
this, which allows for iteration over pages in mon_bin_discontig_get().
mon_bin_discontig_init() increments the rp->mmap_active reference count to
stabilise page spans. Should an error arise the core unmaps the VMA and
mon_bin_vma_close() drops the reference again.
The vm_ops->close hook implemented in mon_bin_vma_close() will ensure
correct reference count arithmetic upon unmap (with mon_bin_vma_open()
accounting for splitting).
The existing semantics are all retained, including not mapping past the
range of available pages, with a SIGBUS being raised in a userland process
that attempts to access past this point.
Ultimately insert_page() is invoked to insert each page, which increments
the reference count on each mapped page. This mimics what was being done
previously, only we pre-map the entire range rather than doing so on
demand.
The existing fault handler did nothing that required demand paging, and was
presumably implemented this way for historical reasons.
One behavioural difference: pages are no longer faulted in on demand, so a
page discarded with MADV_DONTNEED is not repopulated and a subsequent
access raises SIGBUS, as with other pre-populated kernel mappings.

All present section iterators run before memory hotplug added any further
memory sections, Therefore, we can simply use the SECTION_IS_EARLY flag by
setting that flag earlier in sparse_sections_init().
Get rid of SECTION_MARKED_PRESENT entirely and rename
for_each_present_section_nr() to for_each_early_section_nr().
Take care of the .clang-format for_each_present_section_nr() handling.
No functional change intended.

read_block_state() formats each entry directly into the buffer supplied by
read(). If the remaining buffer is too small for one complete record,
snprintf() returns the full record length and the function stops without
copying data or advancing the file position. A read from this debugfs
file which is smaller than a record therefore returns zero at a non-EOF
position and cannot make progress.
Convert block_state to seq_file so formatted records are buffered
independently of the userspace read size. Keep dev_lock held across each
seq_file iteration and continue to protect individual entries with their
slot locks.

dma_alloc_coherent() allocates the DMA buffer with the device's
addressing limitation in mind; the DMA core picks the zone from the
device's coherent DMA mask and ignores GFP_DMA passed by the caller.
Use GFP_KERNEL instead so the allocation may reclaim as usual for
probe-time allocations.
