Use disable_work_sync() instead of cancel_work_sync() in ivpu_dev_fini()
to ensure that no new recovery work items can be queued after device
removal has started. Previously, recovery work could be scheduled even
after canceling existing work, potentially leading to use-after-free
bugs if recovery accessed freed resources.
Rename ivpu_pm_cancel_recovery() to ivpu_pm_disable_recovery() to better
reflect its new behavior.

Nouveau has code that when it gets an IRQ with no allowed handler
it disables it to avoid storms.
However with nonstall interrupts, we often disable them from
the drm driver, but still request their emission via the push submission.
Just don't disable nonstall irqs ever in normal operation, the
event handling code will filter them out, and the driver will
just enable/disable them at load time.
This fixes timeouts we've been seeing on/off for a long time,
but they became a lot more noticeable on Blackwell.
This doesn't fix all of them, there is a subsequent fence emission
fix to fix the last few.

This reverts commit 482c7e296e.
The dma_buf field in struct drm_gem_object is not stable over the
object instance's lifetime. The field becomes NULL when user space
releases the final GEM handle on the buffer object. This resulted
in a NULL-pointer deref.
Workarounds in commit 5307dce878 ("drm/gem: Acquire references on
GEM handles for framebuffers") and commit f6bfc9afc7 ("drm/framebuffer:
Acquire internal references on GEM handles") only solved the problem
partially. They especially don't work for buffer objects without a DRM
framebuffer associated.
Hence, this revert to going back to using .import_attach->dmabuf.

Current dma-buf vmap semantics require that the mapped buffer remains
in place until the corresponding vunmap has completed.
For GEM-SHMEM, this used to be guaranteed by a pin operation while creating
an S/G table in import. GEM-SHMEN can now import dma-buf objects without
creating the S/G table, so the pin is missing. Leads to page-fault errors,
such as the one shown below.

In this stack strace, udl (based on GEM-SHMEM) imported and vmap'ed a
dma-buf from amdgpu. Amdgpu relocated the buffer, thereby invalidating the
mapping.
Provide a custom dma-buf vmap method in amdgpu that pins the object before
mapping it's buffer's pages into kernel address space. Do the opposite in
vunmap.
Note that dma-buf vmap differs from GEM vmap in how it handles relocation.
While dma-buf vmap keeps the buffer in place, GEM vmap requires the caller
to keep the buffer in place. Hence, this fix is in amdgpu's dma-buf code
instead of its GEM code.
A discussion of various approaches to solving the problem is available
at [1].

One core change removing the 'w' access flag of attributes that don't
have a set routine (and therefore can't be written to) which should
have no practical impact. The big scsi_debug update is caused by
reformatting lots of arrays and the rest of the bug fixes in drivers

In 32-bit arm, the build fails with:

help: you can convert a `u32` to a `u64`
|
42 | getparam.set_value(value.into());
| +++++++
The reason is that `Getparam::set_value` takes a `u64` (from the UAPI),
but `pci::Device::resource_len()` returns a `resource_size_t`, which is a
`phys_addr_t`, which may be 32- or 64-bit.
Thus add an `into()` call to support the 32-bit case, while allowing the
Clippy lint that complains in the 64-bit case where the type is the same.

7ffeb2fc26 ("x86/sev: Document requirement for linear mapping of guest request buffers")
added a check that requires the guest request buffers to be in the linear
mapping. The get_derived_key() function was passing a buffer that was
allocated on the stack, resulting in the call to snp_send_guest_request()
returning an error.
Update the get_derived_key() function to use an allocated buffer instead
of a stack buffer.

devm_drm_bridge_alloc() returns ERR_PTR on failure instead of a
NULL pointer, so use IS_ERR() to check the returned pointer.
While at it, on failure, return ERR_CAST(dp) instead of
ERR_PTR(-ENOMEM) in order not to depend on devm_drm_bridge_alloc()
error code implementation.

This set of fixes includes a solution for the issue described in the tag
annotation for v6.17 updates.
The issue involved a potential call to schedule() within an RCU read-side
critical section. The solution applies reference counting to ensure that
handlers which may call schedule() are invoked safely outside of the
critical section.

LMEM is partitioned between multiple VFs and we expect that the more
VFs we have, the less LMEM is assigned to each VF.
This means that we can achieve full LMEM BAR access without the need to
attempt full VF LMEM BAR resize via pci_resize_resource().
Always try to set the largest possible BAR size that allows to fit the
number of enabled VFs and inform the user in case the resize attempt is
not successful.
