Revert "drm/amdkfd: Use partial migrations in GPU page faults"
This reverts commit
dc427a473e5d119232ddb27530920d9796cdea70.
The change prevents migrating the entire range to VRAM because retry
fault restore_pages map the remaining system memory range to GPUs. It
will work correctly to submit together with partial mapping to GPU
patch later.

drm/amd/display: Reduce stack size by splitting function
When compiling with allmodconfig, gcc highlights the following error:
drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c: In function 'dml_core_mode_support':
drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c:8229:1: error: the frame size of 2736 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]

cc1: all warnings being treated as errors
This commit mitigates part of this problem by extracting the prefetch
code to its own function. After applying this commit, the stack size
reduces from 2736 to 2464, however, the stack size issue becomes part of
the new function.

efi/unaccepted: Fix soft lockups caused by parallel memory acceptance
Michael reported soft lockups on a system that has unaccepted memory.
This occurs when a user attempts to allocate and accept memory on
multiple CPUs simultaneously.
The root cause of the issue is that memory acceptance is serialized with
a spinlock, allowing only one CPU to accept memory at a time. The other
CPUs spin and wait for their turn, leading to starvation and soft lockup
reports.
To address this, the code has been modified to release the spinlock
while accepting memory. This allows for parallel memory acceptance on
multiple CPUs.
A newly introduced "accepting_list" keeps track of which memory is
currently being accepted. This is necessary to prevent parallel
acceptance of the same memory block. If a collision occurs, the lock is
released and the process is retried.
Such collisions should rarely occur. The main path for memory acceptance
is the page allocator, which accepts memory in MAX_ORDER chunks. As long
as MAX_ORDER is equal to or larger than the unit_size, collisions will
never occur because the caller fully owns the memory block being
accepted.
Aside from the page allocator, only memblock and deferered_free_range()
accept memory, but this only happens during boot.
The code has been tested with unit_size == 128MiB to trigger collisions
and validate the retry codepath.

tracing/kprobes: Return EADDRNOTAVAIL when func matches several symbols
When a kprobe is attached to a function that's name is not unique (is
static and shares the name with other functions in the kernel), the
kprobe is attached to the first function it finds. This is a bug as the
function that it is attaching to is not necessarily the one that the
user wants to attach to.
Instead of blindly picking a function to attach to what is ambiguous,
error with EADDRNOTAVAIL to let the user know that this function is not
unique, and that the user must use another unique function with an
address offset to get to the function they want to attach to.
