630efee949 drm: Fix object leak in DRM_IOCTL_GEM_CHANGE_HANDLE
Add missing drm_gem_object_put() call when drm_gem_object_lookup()
successfully returns an object. This fixes a GEM object reference
leak that can prevent driver modules from unloading when using
prime buffers.

526aafabd7 drm/tests: Handle EDEADLK in set_up_atomic_state()
Fedora/CentOS/RHEL CI is reporting intermittent failures while running
the drm_validate_modeset test [1]:

    # drm_test_check_connector_changed_modeset: EXPECTATION FAILED at
    # drivers/gpu/drm/tests/drm_atomic_state_test.c:162
    Expected ret == 0, but

Change the set_up_atomic_state() helper function to return on error and
restart the atomic sequence when the returned error is EDEADLK.

Fedora/CentOS/RHEL CI is reporting intermittent failures while running

    # drivers/gpu/drm/tests/drm_atomic_state_test.c:295
    Expected ret == param->expected_result, but

fe27e709d9 drm/tests: hdmi: Handle drm_kunit_helper_enable_crtc_connector() returning EDEADLK
Fedora/CentOS/RHEL CI is reporting intermittent failures while running
the KUnit tests present in drm_hdmi_state_helper_test.c [1].

While the specific test causing the failure change between runs, all of
them are caused by drm_kunit_helper_enable_crtc_connector() returning
-EDEADLK. The error trace always follow this structure:

    # <test name>: ASSERTION FAILED at
    # drivers/gpu/drm/tests/drm_hdmi_state_helper_test.c:<line>
    Expected ret == 0, but
        ret == -35 (0xffffffffffffffdd)

As documented, if the drm_kunit_helper_enable_crtc_connector() function
returns -EDEADLK (-35), the entire atomic sequence must be restarted.

Handle this error code for all function calls.

a585c7ef9c drm/tilcdc: Fix removal actions in case of failed probe
The drm_kms_helper_poll_fini() and drm_atomic_helper_shutdown() helpers
should only be called when the device has been successfully registered.
Currently, these functions are called unconditionally in tilcdc_fini(),
which causes warnings during probe deferral scenarios.

Fix this by rewriting the failed probe cleanup path using the standard
goto error handling pattern, which ensures that cleanup functions are
only called on successfully initialized resources. Additionally, remove
the now-unnecessary is_registered flag.

491adc6a0f drm/ttm: Avoid NULL pointer deref for evicted BOs
It is possible for a BO to exist that is not currently associated with a
resource, e.g. because it has been evicted.

When devcoredump tries to read the contents of all BOs for dumping, we need
to expect this as well -- in this case, ENODATA is recorded instead of the
buffer contents.

This is caused by the i2c encoder modules vendored into nouveau/ now
depending on the equally vendored nouveau_i2c_encoder_destroy
function. Trying to auto-load this modules hangs on nouveau
initialization until timeout, and nouveau continues without i2c video
encoders.

Fix by avoiding nouveau dependency by __always_inlining that helper
functions into those i2c video encoder modules.

PLL_UNLOCK error going active. Analysis suggested the board is unable to
provide the correct DSI clock neede by the SN65DSI84, to which the TI
SN65DSI84 reacts by raising the PLL_UNLOCK, while the display still works
apparently without issues.

On other hardware, where all the clocks are within the components
specifications, the PLL_UNLOCK bit does not trigger while the display is in
normal use. It can trigger for e.g. electromagnetic interference, which is
a transient event and exactly the reason why the error recovery mechanism
has been implemented.

Idelly the PLL_UNLOCK bit could be ignored when working out of
specification, but this requires to detect in software whether it triggers
because the device is working out of specification but visually correctly
for the user or for good reasons (e.g. EMI, or even because working out of
specifications but compromising the visual output).

The ongoing analysis as of this writing [1][2] has not yet found a way for
the driver to discriminate among the two cases. So as a temporary measure
mask the PLL_UNLOCK error bit unconditionally.

The reason this happens is because the fwsec-sb firmware image only
supports being booted from a contiguous coherent sysmem allocation. If a
system runs into enough memory fragmentation from memory pressure, such as
what can happen on systems with low amounts of memory, this can lead to a
situation where it later becomes impossible to find space for a large
enough contiguous allocation to hold fwsec-sb. This causes us to fail to
boot the firmware image, causing the GPU to fail booting and causing the
driver to fail.

Since this firmware can't use non-contiguous allocations, the best solution
to avoid this issue is to simply allocate the memory for fwsec-sb during
initial driver-load, and reuse the memory allocation when fwsec-sb needs to
be used. We then release the memory allocations on driver unload.

eb76d0f555 drm, fbcon, vga_switcheroo: Avoid race condition in fbcon setup
Protect vga_switcheroo_client_fb_set() with console lock. Avoids OOB
access in fbcon_remap_all(). Without holding the console lock the call
races with switching outputs.

VGA switcheroo calls fbcon_remap_all() when switching clients. The fbcon
function uses struct fb_info.node, which is set by register_framebuffer().
As the fb-helper code currently sets up VGA switcheroo before registering
the framebuffer, the value of node is -1 and therefore not a legal value.
For example, fbcon uses the value within set_con2fb_map() [1] as an index
into an array.

Moving vga_switcheroo_client_fb_set() after register_framebuffer() can
result in VGA switching that does not switch fbcon correctly.

Therefore move vga_switcheroo_client_fb_set() under fbcon_fb_registered(),
which already holds the console lock. Fbdev calls fbcon_fb_registered()
from within register_framebuffer(). Serializes the helper with VGA
switcheroo's call to fbcon_remap_all().

Although vga_switcheroo_client_fb_set() takes an instance of struct fb_info
as parameter, it really only needs the contained fbcon state. Moving the
call to fbcon initialization is therefore cleaner than before. Only amdgpu,
i915, nouveau and radeon support vga_switcheroo. For all other drivers,
this change does nothing.

d6732ef4ab drm/bridge: sii902x: Fix HDMI detection with DRM_BRIDGE_ATTACH_NO_CONNECTOR
The sii902x driver was caching HDMI detection state in a sink_is_hdmi field
and checking it in mode_set() to determine whether to set HDMI or DVI
output mode. This approach had two problems:

1. With DRM_BRIDGE_ATTACH_NO_CONNECTOR (used by modern display drivers like
TIDSS), the bridge's get_modes() is never called. Instead, the
drm_bridge_connector helper calls the bridge's edid_read() and updates the
connector itself. This meant sink_is_hdmi was never populated, causing the
driver to default to DVI mode and breaking HDMI audio.

2. The mode_set() callback doesn't receive atomic state or connector
pointer, making it impossible to check connector->display_info.is_hdmi
directly at that point.

Fix this by moving the HDMI vs DVI decision from mode_set() to
atomic_enable(), where we can access the connector via
drm_atomic_get_new_connector_for_encoder(). This works for both connector
models:

- With DRM_BRIDGE_ATTACH_NO_CONNECTOR: Returns the drm_bridge_connector
  created by the display driver, which has already been updated by the
helper's call to drm_edid_connector_update()

- Without DRM_BRIDGE_ATTACH_NO_CONNECTOR (legacy): Returns the connector
  embedded in sii902x struct, which gets updated by the bridge's own
get_modes()

1c2a936edd mm, swap: fix potential UAF issue for VMA readahead
Since commit 78524b05f1 ("mm, swap: avoid redundant swap device
pinning"), the common helper for allocating and preparing a folio in the
swap cache layer no longer tries to get a swap device reference
internally, because all callers of __read_swap_cache_async are already
holding a swap entry reference.  The repeated swap device pinning isn't
needed on the same swap device.

Caller of VMA readahead is also holding a reference to the target entry's
swap device, but VMA readahead walks the page table, so it might encounter
swap entries from other devices, and call __read_swap_cache_async on
another device without holding a reference to it.

So it is possible to cause a UAF when swapoff of device A raced with
swapin on device B, and VMA readahead tries to read swap entries from

issues.

Make VMA readahead try to get the device reference first if the swap
device is a different one from the target entry.

216158f063 selftests/user_events: fix type cast for write_index packed member in perf_test
Accessing 'reg.write_index' directly triggers a -Waddress-of-packed-member
warning due to potential unaligned pointer access:

perf_test.c:239:38: warning: taking address of packed member 'write_index'
of class or structure 'user_reg' may result in an unaligned pointer value
[-Waddress-of-packed-member]
  239 |         ASSERT_NE(-1, write(self->data_fd, &reg.write_index,
      |                                             ^~~~~~~~~~~~~~~

Since write(2) works with any alignment. Casting '&reg.write_index'
explicitly to 'void *' to suppress this warning.

f1d47cafe5 mm/huge_memory: fix folio split check for anon folios in swapcache
Both uniform and non uniform split check missed the check to prevent
splitting anon folios in swapcache to non-zero order.

Splitting anon folios in swapcache to non-zero order can cause data
corruption since swapcache only support PMD order and order-0 entries. 
This can happen when one use split_huge_pages under debugfs to split
anon folios in swapcache.

In-tree callers do not perform such an illegal operation.  Only debugfs
interface could trigger it.  I will put adding a test case on my TODO
list.

Fix the check.

00fbff75c5 crash: fix crashkernel resource shrink
When crashkernel is configured with a high reservation, shrinking its
value below the low crashkernel reservation causes two issues:

1. Invalid crashkernel resource objects
2. Kernel crash if crashkernel shrinking is done twice

For example, with crashkernel=200M,high, the kernel reserves 200MB of high
memory and some default low memory (say 256MB).  The reservation appears
as:

cat /proc/iomem | grep -i crash
af000000-beffffff : Crash kernel
433000000-43f7fffff : Crash kernel

If crashkernel is then shrunk to 50MB (echo 52428800 >
/sys/kernel/kexec_crash_size), /proc/iomem still shows 256MB reserved:
af000000-beffffff : Crash kernel

Instead, it should show 50MB:
af000000-b21fffff : Crash kernel

Further shrinking crashkernel to 40MB causes a kernel crash with the
following trace (x86):

BUG: kernel NULL pointer dereference, address: 0000000000000038

This happens because __crash_shrink_memory()/kernel/crash_core.c
incorrectly updates the crashk_res resource object even when
crashk_low_res should be updated.

Fix this by ensuring the correct crashkernel resource object is updated
when shrinking crashkernel memory.

39231e8d6b mm: fix MAX_FOLIO_ORDER on powerpc configs with hugetlb
In the past, CONFIG_ARCH_HAS_GIGANTIC_PAGE indicated that we support
runtime allocation of gigantic hugetlb folios.  In the meantime it evolved
into a generic way for the architecture to state that it supports gigantic
hugetlb folios.

In commit fae7d834c4 ("mm: add __dump_folio()") we started using
CONFIG_ARCH_HAS_GIGANTIC_PAGE to decide MAX_FOLIO_ORDER: whether we could
have folios larger than what the buddy can handle.  In the context of that
commit, we started using MAX_FOLIO_ORDER to detect page corruptions when
dumping tail pages of folios.  Before that commit, we assumed that we
cannot have folios larger than the highest buddy order, which was
obviously wrong.

In commit 7b4f21f5e0 ("mm/hugetlb: check for unreasonable folio sizes
when registering hstate"), we used MAX_FOLIO_ORDER to detect
inconsistencies, and in fact, we found some now.

Powerpc allows for configs that can allocate gigantic folio during boot
(not at runtime), that do not set CONFIG_ARCH_HAS_GIGANTIC_PAGE and can
exceed PUD_ORDER.

To fix it, let's make powerpc select CONFIG_ARCH_HAS_GIGANTIC_PAGE with
hugetlb on powerpc, and increase the maximum folio size with hugetlb to 16
GiB on 64bit (possible on arm64 and powerpc) and 1 GiB on 32 bit
(powerpc).  Note that on some powerpc configurations, whether we actually
have gigantic pages depends on the setting of CONFIG_ARCH_FORCE_MAX_ORDER,
but there is nothing really problematic about setting it unconditionally:
we just try to keep the value small so we can better detect problems in
__dump_folio() and inconsistencies around the expected largest folio in
the system.

Ideally, we'd have a better way to obtain the maximum hugetlb folio size
and detect ourselves whether we really end up with gigantic folios.  Let's
defer bigger changes and fix the warnings first.

While at it, handle gigantic DAX folios more clearly: DAX can only end up
creating gigantic folios with HAVE_ARCH_TRANSPARENT_HUGEPAGE_PUD.

Add a new Kconfig option HAVE_GIGANTIC_FOLIOS to make both cases clearer. 
In particular, worry about ARCH_HAS_GIGANTIC_PAGE only with HUGETLB_PAGE.

Note: with enabling CONFIG_ARCH_HAS_GIGANTIC_PAGE on powerpc, we will now
also allow for runtime allocations of folios in some more powerpc configs.
I don't think this is a problem, but if it is we could handle it through
__HAVE_ARCH_GIGANTIC_PAGE_RUNTIME_SUPPORTED.

While __dump_page()/__dump_folio was also problematic (not handling
dumping of tail pages of such gigantic folios correctly), it doesn't seem
critical enough to mark it as a fix.

de90cc610e spi: Fixes for v6.18
A few standard fixes here, plus one more interesting one from Hans which
 addresses an issue where a move in when we requested GPIOs on ACPI
 systems caused us to stop doing pinmuxing and leave things floating that
 we'd really rather not have floating.
