Pull RISC-V fixes from Paul Walmsley:
- Fix a CONFIG_SPARSEMEM crash on RV32 by avoiding early phys_to_page()
- Prevent runtime const infrastructure from being used by modules,
similar to what was done for x86
- Avoid problems when shutting down ACPI systems with IOMMUs by adding
a device dependency between IOMMU and devices that use it
- Fix a bug where the CPU pointer masking state isn't properly reset
when tagged addresses aren't enabled for a task
- Fix some incorrect register assignments, and add some missing ones,
in kgdb support code
- Fix compilation of non-kernel code that uses the ptrace uapi header
by replacing BIT() with _BITUL()
- Fix compilation of the validate_v_ptrace kselftest by working around
kselftest macro expansion issues

In eb_lookup_vma(), the code checks that the context vm matches before
incrementing the i915 vma usage count, but for the non-matching case it
didn't clear the non-matching vma pointer, so it would then mistakenly
be returned, causing potential UaF and refcount issues.

Pull char/misc/iio driver fixes from Greg KH:
"Here are a relativly large number of small char/misc/iio and other
driver fixes for 7.0-rc7. There's a bunch, but overall they are all
small fixes for issues that people have been having that I finally
caught up with getting merged due to delays on my end.
The "largest" change overall is just some documentation updates to the
security-bugs.rst file to hopefully tell the AI tools (and any users
that actually read the documentation), how to send us better security
bug reports as the quantity of reports these past few weeks has
increased dramatically due to tools getting better at "finding"
things.
Included in here are:
- lots of small IIO driver fixes for issues reported in 7.0-rc
- gpib driver fixes
- comedi driver fixes
- interconnect driver fix
- nvmem driver fixes
- mei driver fix
- counter driver fix
- binder rust driver fixes
- some other small misc driver fixes
All of these have been in linux-next this week with no reported issues"

Pull USB/Thunderbolt fixes from Greg KH:
"Here are a bunch of USB and Thunderbolt fixes (most all are USB) for
7.0-rc7. More than I normally like this late in the release cycle,
partly due to my recent travels, and partly due to people banging away
on the USB gadget interfaces and apis more than normal (big shoutout
to Android for getting the vendors to actually work upstream on this,
that's a huge win overall for everyone here)
Included in here are:
- Small thunderbolt fix
- new USB serial driver ids added
- typec driver fixes
- gadget driver fixes for some disconnect issues
- other usb gadget driver fixes for reported problems with binding
and unbinding devices as happens when a gadget device connects /
disconnects from a system it is plugged into (or it switches device
mode at a user's request, these things are complex little
beasts...)
- usb offload fixes (where USB audio tunnels through the controller
while the main CPU is asleep) for when EMP spikes hit the system
causing disconnects to happen (as often happens with static
electricity in the winter months). This has been much reported by
at least one vendor, and resolves the issues they have been seeing
with this codepath. Can't wait for the "formal methods are the
answer!" people to try to model that one properly...
- Other small usb driver fixes for issues reported.
All of these have been in linux-next this week, and before, with no
reported issues, and I've personally been stressing these harder than
normal on my systems here with no problems"

EPROBE_DEFER ensures IOMMU devices are probed before the devices that
depend on them. During shutdown, however, the IOMMU may be removed
first, leading to issues. To avoid this, a device link is added
which enforces the correct removal order.

Add device IDs for the Razer Wolverine V3 Pro controller in both
wired (0x0a57) and wireless 2.4 GHz dongle (0x0a59) modes.
The controller uses the Xbox 360 protocol (vendor-specific class,
subclass 93, protocol 1) on interface 0 with an identical 20-byte
input report layout, so no additional processing is needed.

Description:
- Commit b82f0759346617b2 ("drm/amd/display: Migrate DIO registers access
from hwseq to dio component") moved DIO_MEM_PWR_CTRL register access
behind the new dio abstraction layer but only created the dio object for
DCN 4.01. On all other generations (DCN 10/20/21/201/30/301/302/303/
31/314/315/316/32/321/35/351/36), the dio pointer is NULL, causing the
register write to be silently skipped.
This results in AFMT HDMI memory not being powered on during init_hw,
which can cause HDMI audio failures and display issues on affected
hardware including Renoir/Cezanne (DCN 2.1) APUs that use dcn10_init_hw.
Call dcn10_dio_construct() in each older DCN generation's resource.c
to create the dio object, following the same pattern as DCN 4.01. This
ensures the dio pointer is non-NULL and the mem_pwr_ctrl callback works
through the dio abstraction for all DCN generations.

On systems with 64K pages, RX queues will be wedged if users set the
descriptor count to the current minimum (16). Fbnic fragments large
pages into 4K chunks, and scales down the ring size accordingly. With
64K pages and 16 descriptors, the ring size mask is 0 and will never
be filled.
32 descriptors is another special case that wedges the RX rings.
Internally, the rings track pages for the head/tail pointers, not page
fragments. So with 32 descriptors, there's only 1 usable page as one
ring slot is kept empty to disambiguate between an empty/full ring.
As a result, the head pointer never advances and the HW stalls after
consuming 16 page fragments.

fastrpc_init_create_static_process() may free cctx->remote_heap on the

frees cctx->remote_heap again if it is non-NULL, which can lead to a

The dt2815 driver crashes when attached to I/O ports without actual
hardware present. This occurs because syzkaller or users can attach
the driver to arbitrary I/O addresses via COMEDI_DEVCONFIG ioctl.
When no hardware exists at the specified port, inb() operations return
0xff (floating bus), but outb() operations can trigger page faults due
to undefined behavior, especially under race conditions:
BUG: unable to handle page fault for address: 000000007fffff90
#PF: supervisor write access in kernel mode
#PF: error_code(0x0002) - not-present page
RIP: 0010:dt2815_attach+0x6e0/0x1110
Add hardware detection by reading the status register before attempting
any write operations. If the read returns 0xff, assume no hardware is
present and fail the attach with -ENODEV. This prevents crashes from
outb() operations on non-existent hardware.

syzbot reported a memory leak [1], because commit 4e1da516debb ("comedi:
Add reference counting for Comedi command handling") did not consider
the exceptional exit case in do_cmd_ioctl() where runflags is not set.
This caused chanlist not to be properly freed by do_become_nonbusy(),
as it only frees chanlist when runflags is correctly set.
Added a check in do_become_nonbusy() for the case where runflags is not
set, to properly free the chanlist memory.

`struct comedi_device` is the main controlling structure for a COMEDI
device created by the COMEDI subsystem. It contains a member `spinlock`
containing a spin-lock that is initialized by the COMEDI subsystem, but
is reserved for use by a low-level driver attached to the COMEDI device
(at least since commit 25436dc9d84f ("Staging: comedi: remove RT
code")).
Some COMEDI devices (those created on initialization of the COMEDI
subsystem when the "comedi.comedi_num_legacy_minors" parameter is
non-zero) can be attached to different low-level drivers over their
lifetime using the `COMEDI_DEVCONFIG` ioctl command. This can result in
inconsistent lock states being reported when there is a mismatch in the
spin-lock locking levels used by each low-level driver to which the
COMEDI device has been attached. Fix it by reinitializing
`dev->spinlock` before calling the low-level driver's `attach` function
pointer if `CONFIG_LOCKDEP` is enabled.

If the driver's COMEDI "attach" handler function (`atmio16d_attach()`)
returns an error, the COMEDI core will call the driver's "detach"
handler function (`atmio16d_detach()`) to clean up. This calls
`reset_atmio16d()` unconditionally, but depending on where the error
occurred in the attach handler, the device may not have been
sufficiently initialized to call `reset_atmio16d()`. It uses
`dev->iobase` as the I/O port base address and `dev->private` as the
pointer to the COMEDI device's private data structure. `dev->iobase`
may still be set to its initial value of 0, which would result in
undesired writes to low I/O port addresses. `dev->private` may still be
`NULL`, which would result in null pointer dereferences.
Fix `atmio16d_detach()` by checking that `dev->private` is valid
(non-null) before calling `reset_atmio16d()`. This implies that
`dev->iobase` was set correctly since that is set up before
`dev->private`.

The IBRD, IBWRT, IBCMD, and IBWAIT ioctl handlers use a gpib_descriptor
pointer after board->big_gpib_mutex has been released. A concurrent
IBCLOSEDEV ioctl can free the descriptor via close_dev_ioctl() during
this window, causing a use-after-free.
The IO handlers (read_ioctl, write_ioctl, command_ioctl) explicitly
release big_gpib_mutex before calling their handler. wait_ioctl() is
called with big_gpib_mutex held, but ibwait() releases it internally
when wait_mask is non-zero. In all four cases, the descriptor pointer
obtained from handle_to_descriptor() becomes unprotected.
Fix this by introducing a kernel-only descriptor_busy reference count
in struct gpib_descriptor. Each handler atomically increments
descriptor_busy under file_priv->descriptors_mutex before releasing the
lock, and decrements it when done. close_dev_ioctl() checks
descriptor_busy under the same lock and rejects the close with -EBUSY
if the count is non-zero.
A reference count rather than a simple flag is necessary because
multiple handlers can operate on the same descriptor concurrently
(e.g. IBRD and IBWAIT on the same handle from different threads).
A separate counter is needed because io_in_progress can be cleared from
unprivileged userspace via the IBWAIT ioctl (through general_ibstatus()
with set_mask containing CMPL), which would allow an attacker to bypass
a check based solely on io_in_progress. The new descriptor_busy
counter is only modified by the kernel IO paths.
The lock ordering is consistent (big_gpib_mutex -> descriptors_mutex)
and the handlers only hold descriptors_mutex briefly during the lookup,
so there is no deadlock risk and no impact on IO throughput.

There was an issue when you did the following:
- setup and bind an hid gadget
- open /dev/hidg0
- use the resulting fd in EPOLL_CTL_ADD
- unbind the UDC
- bind the UDC
- use the fd in EPOLL_CTL_DEL
When CONFIG_DEBUG_LIST was enabled, a list_del corruption was reported
within remove_wait_queue (via ep_remove_wait_queue). After some
debugging I found out that the queues, which f_hid registers via
poll_wait were the problem. These were initialized using
init_waitqueue_head inside hidg_bind. So effectively, the bind function
re-initialized the queues while there were still items in them.
The solution is to move the initialization from hidg_bind to hidg_alloc
to extend their lifetimes to the lifetime of the function instance.
Additionally, I found many other possibly problematic init calls in the
bind function, which I moved as well.

When cdns3_gadget_start() fails, the DRD hardware is left in gadget mode
while software state remains INACTIVE, creating hardware/software state
inconsistency.
When switching to host mode via sysfs:
echo host > /sys/class/usb_role/13180000.usb-role-switch/role
The role state is not set to CDNS_ROLE_STATE_ACTIVE due to the error,
so cdns_role_stop() skips cleanup because state is still INACTIVE.
This violates the DRD controller design specification (Figure22),
which requires returning to idle state before switching roles.
This leads to a synchronous external abort in xhci_gen_setup() when

f_audio_complete() copies req->length bytes into a 4-byte stack
variable:
u32 data = 0;
memcpy(&data, req->buf, req->length);
req->length is derived from the host-controlled USB request path,
which can lead to a stack out-of-bounds write.
Validate req->actual against the expected payload size for the
supported control selectors and decode only the expected amount
of data.
This avoids copying a host-influenced length into a fixed-size

When device_register() fails, ulpi_register() calls put_device() on
ulpi->dev.
The device release callback ulpi_dev_release() drops the OF node
reference and frees ulpi, but the current error path in
ulpi_register_interface() then calls kfree(ulpi) again, causing a
double free.
Let put_device() handle the cleanup through ulpi_dev_release() and
avoid freeing ulpi again in ulpi_register_interface().

When usb_submit_urb() fails in usbio_probe(), the previously allocated
URB is never freed, causing a memory leak.
Fix this by jumping to err_free_urb label to properly release the URB
on the error path.
