Commit 16ce101db85d ("mm/memory.c: fix race when faulting a device private
page") changed the migrate_to_ram() callback to take a reference on the
device page to ensure it can't be freed while handling the fault.
Unfortunately the corresponding update to Nouveau to accommodate this
change was inadvertently dropped from that patch causing GPU to CPU
migration to fail so add it here.

Commit 8795e182b02d ("PCI/portdrv: Don't disable AER reporting in get_port_device_capability()")
uncovered a bug in amdgpu that required a reordering of the driver
init sequence to avoid accessing a special register on the GPU
before it was properly set up leading to an PCI AER error. This
reordering uncovered a different hw programming ordering dependency
in some APUs where the SDMA doorbells need to be programmed before
the GFX doorbells. To fix this, move the SDMA doorbell programming
back into the soc15 common code, but use the actual doorbell range
values directly rather than the values stored in the ring structure
since those will not be initialized at this point.
This is a partial revert, but with the doorbell assignment
fixed so the proper doorbell index is set before it's used.

__le32 and __le64 types aren't portable and are not available on
FreeBSD (which uses the same uAPI).
Instead of attempting to always output little endian, just use native
endianness in the dumps. Tools can detect the endianness in use by
looking at the 'magic' field, but equally we don't expect big-endian to
be used with Mali (there are no known implementations out there).

Commit 35a3b82f1bdd ("drm/connector: Introduce drmm_connector_init")
introduced the function drmm_connector_init() with a parameter for an
optional ddc pointer to the i2c controller used to access the DDC bus.
However, the underlying call to __drm_connector_init() was always
setting it to NULL instead of passing the ddc argument around.
This resulted in unexpected null pointer dereference on platforms
expecting to get a DDC controller.

The xrgb2101010 format conversion test (unlike for other formats) does
an endianness conversion on the results. However, it always converts
TEST_BUF_SIZE 32-bit integers, which results in reading from (and
writing to) more memory than in present in the result buffer. Instead,
use the buffer size, divided by sizeof(u32).
The issue could be reproduced with KASAN:
./tools/testing/kunit/kunit.py run --kunitconfig drivers/gpu/drm/tests \
--kconfig_add CONFIG_KASAN=y --kconfig_add CONFIG_KASAN_VMALLOC=y \

When booting a kernel compiled with CONFIG_CFI_CLANG on a machine with
an RX 6700 XT, there is a CFI failure in kfd_destroy_mqd_cp():
[ 12.894543] CFI failure at kfd_destroy_mqd_cp+0x2a/0x40 [amdgpu] (target: hqd_destroy_v10_3+0x0/0x260 [amdgpu]; expected type: 0x8594d794)
Clang's kernel Control Flow Integrity (kCFI) makes sure that all
indirect call targets have a type that exactly matches the function
pointer prototype. In this case, hqd_destroy()'s third parameter,
reset_type, should have a type of 'uint32_t' but every implementation of
this callback has a third parameter type of 'enum kfd_preempt_type'.
Update the function pointer prototype to match reality so that there is
no more CFI violation.

This is seen when building i386:allmodconfig with any of the following

gcc (Debian 12.2.0-3) 12.2.0
gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0
The problem is not seen if the compiler supports GCC_PLUGIN_LATENT_ENTROPY

Pull more random number generator updates from Jason Donenfeld:
"This time with some large scale treewide cleanups.
The intent of this pull is to clean up the way callers fetch random
integers. The current rules for doing this right are:
- If you want a secure or an insecure random u64, use get_random_u64()
- If you want a secure or an insecure random u32, use get_random_u32()
The old function prandom_u32() has been deprecated for a while
now and is just a wrapper around get_random_u32(). Same for
get_random_int().
- If you want a secure or an insecure random u16, use get_random_u16()
- If you want a secure or an insecure random u8, use get_random_u8()
- If you want secure or insecure random bytes, use get_random_bytes().
The old function prandom_bytes() has been deprecated for a while
now and has long been a wrapper around get_random_bytes()
- If you want a non-uniform random u32, u16, or u8 bounded by a
certain open interval maximum, use prandom_u32_max()
I say "non-uniform", because it doesn't do any rejection sampling
or divisions. Hence, it stays within the prandom_*() namespace, not
the get_random_*() namespace.
I'm currently investigating a "uniform" function for 6.2. We'll see
what comes of that.
By applying these rules uniformly, we get several benefits:
- By using prandom_u32_max() with an upper-bound that the compiler
can prove at compile-time is ≤65536 or ≤256, internally
get_random_u16() or get_random_u8() is used, which wastes fewer
batched random bytes, and hence has higher throughput.
- By using prandom_u32_max() instead of %, when the upper-bound is
not a constant, division is still avoided, because
prandom_u32_max() uses a faster multiplication-based trick instead.
- By using get_random_u16() or get_random_u8() in cases where the
return value is intended to indeed be a u16 or a u8, we waste fewer
batched random bytes, and hence have higher throughput.
This series was originally done by hand while I was on an airplane
without Internet. Later, Kees and I worked on retroactively figuring
out what could be done with Coccinelle and what had to be done
manually, and then we split things up based on that.
So while this touches a lot of files, the actual amount of code that's
hand fiddled is comfortably small"

Move the brace within the #ifdef so that the file can be built with or
without CONFIG_DEBUG_FS.

If our HSM clock has not been properly initialized, any register access
will silently lock up the system.
Let's check that this can't happen by adding a check for the rate before
any register access, and error out otherwise.

This is a revert of commit fd5894fa2413 ("drm/vc4: hdmi: Remove clock
rate initialization"), with the code slightly moved around.
It turns out that we can't downright remove that code from the driver,
since the Pi0-3 and Pi4 are in different cases, and it only works for
the Pi4.
Indeed, the commit mentioned above was relying on the RaspberryPi
firmware clocks driver to initialize the rate if it wasn't done by the
firmware. However, the Pi0-3 are using the clk-bcm2835 clock driver that
wasn't doing this initialization. We therefore end up with the clock not
being assigned a rate, and the CPU stalling when trying to access a
register.
We can't move that initialization in the clk-bcm2835 driver, since the
HSM clock we depend on is actually part of the HDMI power domain, so any
rate setup is only valid when the power domain is enabled. Thus, we
reinstated the minimum rate setup at runtime_suspend, which should
address both issues.

The VC4 HDMI controller driver relies on the HDMI codec ASoC driver. In
order to set it up properly, in vc4_hdmi_audio_init(), our HDMI driver
will register a device matching the HDMI codec driver, and then register
an ASoC card using that codec.
However, if vc4 is compiled as a module, chances are that the hdmi-codec
driver will be too. In such a case, the module loader will have a very
narrow window to load the module between the device registration and the
card registration.
If it fails to load the module in time, the card registration will fail
with EPROBE_DEFER, and we'll abort the audio initialisation,
unregistering the HDMI codec device in the process.
The next time the bind callback will be run, it's likely that we end up
missing that window again, effectively preventing vc4 to probe entirely.
In order to prevent this, we can create a soft dependency of the vc4
driver on the HDMI codec one so that we're sure the HDMI codec will be
loaded before the VC4 module is, and thus we'll never end up in the
previous situation.

When the module is unloaded or a GPU is unbound from the module it is
possible for device private pages to still be mapped in currently running
processes. This can lead to a hangs and RCU stall warnings when unbinding
the device as memunmap_pages() will wait in an uninterruptible state until
all device pages have been freed which may never happen.
Fix this by migrating device mappings back to normal CPU memory prior to
freeing the GPU memory chunks and associated device private pages.

nouveau_dmem_fault_copy_one() is used during handling of CPU faults via
the migrate_to_ram() callback and is used to copy data from GPU to CPU
memory. It is currently specific to fault handling, however a future
patch implementing eviction of data during teardown needs similar
functionality.
Refactor out the core functionality so that it is not specific to fault
handling.

Since 27674ef6c73f ("mm: remove the extra ZONE_DEVICE struct page
refcount") device private pages have no longer had an extra reference
count when the page is in use. However before handing them back to the
owning device driver we add an extra reference count such that free pages
have a reference count of one.
This makes it difficult to tell if a page is free or not because both free
and in use pages will have a non-zero refcount. Instead we should return
pages to the drivers page allocator with a zero reference count. Kernel
code can then safely use kernel functions such as get_page_unless_zero().
